RULE FREEZE FOR THIS VOLUME
With reference to paragraph A.10.2 of CIAM General Rules:
In all classes, the two-year rule for no changes to model aircraft/space model specifications, manoeuvreschedules and competition rules will be strictly enforced. For Championship classes, changes may be
proposed in the year of the World Championship of each category.
For official classes without Championship status, the two-year cycle begins in the year that the Plenary
Meeting approved the official status of the class. For official classes, changes may be proposed in thesecond year of the two-year cycle.
This means that in Volume F5:(a) changes to F5J can be next agreed at the Plenary meeting 2025 for application from January
2026;(b) changes to F5B can be next agreed at the Plenary meeting 2024 for application from January
2025;(c) provisional classes are not subject to this restriction.

is measured, this shall be done at the moment the preparation time for the pilot starts. Afterthe measurement has been taken, the pilot is allowed 5 minutes preparation time as per
5.5.2.4.
b) Battery specifications in F5B, F5E and F5J are written in the special rules of these classes.
c) Mechanical or chemical modification of the individual cells, e.g. to reduce their weight, is notallowed except that insulation sleeves of individual cells may be changed.
d) Electronic systems allowed are:
- Augmented stability systems.
- Systems that limit the energy used during climbs.
e) Electronic systems that are prohibited are:- Autonomous or pre-programmed flight.
- GPS or similar positioning systems or waypoint navigation.
Further exceptions are written in the specific class rules.
5.5.1.4

Energy Limiter/Logger
The energy limiter/logger is located in the electric circuit between the battery and the motor. In thecase of a limiter, the interruption must persist for a defined period of time. Logger data must be
retrieved immediately after the flight. The contest organiser may supply a “real time radio
telemetry logger” that transmits logged data to the ground. The energy data and motor-run data
shall be made available to the pilots.

5.5.1.5

Procedure for Limiter and Logger Checking
The limiters and loggers must be approved by the EDIC (ELECTRONIC DEVICES INCOMPETITIONS WORKING GROUP).
a) The general procedure of limiter and logger checking follows Section C.12, Model Processing,in CIAM General Rules.

CONTEST RULES

5.5.2.1

Definition of an Official Flighta) During a two (2) minute starting period, the competitor is allowed an attempt which starts whenthe model aircraft is released by the competitor or his helper. After two minutes, no further
launching or take off is allowed and the flight is scored with 0 points. The pilot may repeat asecond two minute starting period only if:b) The competitor cannot perform a flight due to outside interference verified by the organiser.
c) No scoring was made for reasons outside the control of the competitor. In such cases, theflight may be repeated at any other time decided by the Contest Director.

5.5.2.2

Cancelling of a Flight and Disqualification
The flight is annulled:a) If the pilot uses a model aircraft that does not conform to the FAI rules. In the case of
intentional or flagrant violation of the rules, in the judgement of the Contest Director, thecompetitor may be disqualified.
b) If the model aircraft loses any part during the flight time. The losing of a part during landing (ie.
contact with the ground or another obstacle) during the flight due to a collision with anothermodel is not taken into account;c) If the model aircraft was already used by another competitor at the same contest;d) If the pilot uses more than two helpers;e) If any part of the model aircraft does not come to rest and remain at rest within 100 metresfrom the landing spot. For powered gliders, this rule applies only after the duration andlanding task has started.
f)

If for powered gliders the duration and landing task has not been started and also the landing
does not occur on the designated flying side of the security line and within 100 m from theintersection of that line with Base A or B.

The amount of energy in one flight must be stored by a logger.
c) Loggers can be provided by the event organisers and will be drawn by the competitor before
the flight. If loggers are provided by the organisers then this is the logger that will be used by
the competitor for the flight/event.
Once drawn, the competitor will have at least 15 minutes to fit the logger into the plane(s).
Immediately after landing, the W*min consumed will be read from the logger which was usedduring the flight, either by means of telemetry or direct cable connection to the logger.
d) The competitor must return the logger(s) after their flight - max 15 minutes.
e) The competitor is responsible for ensuring the logger device is installed correctly. In the eventof an installation failure the competitor will not receive a reflight.
f) The organisers will check each logger prior to it going out to a new competitor to ensure that it
is in full working order.
g) With the logger, 1 (one) point is deducted for every 3 (three) watt-min used over the limit.
h) Starting order for World and Continental Championships: the starting order for the first roundwill be established by random draw. For the next rounds the starting order will follow thereversed ranking list. Frequency will not follow frequency and team member will not follow
team members.
i)Starting order for other competitions:
Before starting the first round the contest director will inform the pilots which mode of startingorder will be established.
Mode A:The starting order for the first round will be established by random draw.
The number of pilots is then divided by the number of rounds giving “x” result.
For each subsequent round, the first number “x” of pilots in the starting order moves to theend of the starting order
Example:Given that there are 24 pilots and four rounds then the calculation results in 6.

SC4_Vol_F5_Electric_24

5.5.4.5

Distance Taska) This task begins when the model aircraft is hand-launched and ends after 200 seconds. Timeof release is to be taken by one timekeeper.
This task must be carried out with at least two climbs with motor running however no morethan ten climbs with the motor running are allowed. No points will be awarded for the legs
completed after an eleventh or more climb with motor running.
The competitor has to decide how much time he will use for each climb (motor run) and how
much for gliding.
b) When after stopping the motor the model aircraft first crosses the Base A in the direction ofBase B, counting of the legs begins. The model aircraft must complete as many legs as
possible from the starting point Base A to the Base B and return;c) Restarting the motor stops counting the legs, as does the expiration of the 200 seconds.
d) A timekeeper or electronic device (if approved by EDIC) announces to the competitor when
his model aircraft crosses the Base A and Base B. The absence of a signal will indicate thatthe model aircraft has failed to correctly cross the base. The instruments used to check thecrossing of the vertical plane must assure the parallelism of such planes.
During the scoring in this task, flying with any part of the model aircraft on the forbidden sideof the safety plane will give ZERO points for the whole flight, distance and duration.
Circumstances beyond the control of the pilot (malfunction of the scoring equipment,interruptions etc) do not permit crossing of the safety plane. A reflight is not permitted if thesafety plane is crossed without the permission of the contest director.
e) The competitor, his helper(s) and the team manager must remain at Base A until the distancepart of the flight is completed. Nobody, other than the Base B signal operator, may stay in the
B line and give signals.
f)Every completed leg will be awarded 10 points. When the model aircraft fails to complete atleast one leg after either of the first two climbs, 30 points will be deducted from the score ofthis task; after 200 seconds of this task, which will be indicated by an audio signal, theduration task begins immediately.

g) Flying out of the distance course at Base A the signal only needs to be given when the model
aircraft is coming directly from Base B.
5.5.4.6

Duration and Landing Taska) This task must be completed within 600 seconds from the moment the audio signal is given.
b) The competitor has to decide how much and how often he will switch on the motor.
c) The duration task score-keeping device keeps track of the motor run time as well as the glide
time. Duration task scoring ends when the model aircraft comes to rest after landing.

Class F5B - Electric Powered Multi Task Glidersd) Duration time is cumulative and one point will be awarded for each full second the model
aircraft is flying. 3 points will be deducted for each 1 second of motor running time.
e) One point will be deducted for each full second flown in excess of 600 seconds.
f) Additional points will be awarded for landing; when the model aircraft comes to rest in the 30
m circle, 10 points will be given while coming to rest in the 20 m circle gives 20 points, andwhen coming to rest in the 10 m circle 30 points will be given. The distances are measured
from the centre of the circle to the nose of the model aircraft.
g) No additional points will be awarded if the landing occurs more than 630 seconds after
beginning of this task (as per 5.5.4.6.a)).
h) Flying through or close to the distance course in a manner that interferes with anothercompetitor’s distance task flight will result in a penalty of 100 points deducted from theoffending competitor’s score of this round. This penalty can be applied by the contest director
or a designated official.
5.5.4.7

Site
The competition must be held at a site having reasonable level terrain with a reasonable low
probability of slope or wave soaring.

5.5.7.1

Definitiona)This is a closed-course energy accumulation, total distance, and landing event for radiocontrolled electric-powered model aircraft using a combination of silicon solar cells andbatteries. The flight shall begin and conclude with a measured state of battery energy. A
penalty shall be applied for finishing with less than the starting battery energy. In thismanner, the battery shall serve primarily as a buffer for solar energy.

b)Model Aircraft Specifications
General Specifications: See paragraph 5.5.1.3.
Solar Array: The solar array must be composed solely of silicon solar cells on the top
surface of the model having area between 21 dm2 and 43 dm2.
Propulsion/Receiver Power Source: See paragraph 5.5.1.3 a) Maximum 42 volts.
The model’s RC control system will use the same power source as is used for propulsion.
No separate battery is allowed for the radio control system.
Either the battery’s balance port or an extension of the battery’s balance port must beaccessible to a 2.54 mm spaced male header connector with model inverted. Alternatively
an approved telemetry based system maybe used to determine the battery voltage.

c)

Model Aircraft Telemetry and Electronics
Model aircraft must be equipped with either GPS telemetry to demonstrate the model’s
position relative to Base A and Base B planes to contest officials, or contest organizers may
provide Base judges to document bases made, communicating this to the contestant’s
helper via flags or “walkie-talkie” radios or other suitable signaling devices.
All other forms of telemetry are specifically allowed.

5.5.7.2

Course Layout and Organisationa)

The course shall be (2) parallel planes 150 meters apart per 5.5.4.2 except that there is no
Safety Plane and contestants may fly on one or both sides of the sighting devices if the fieldboundaries permit it. Contestants shall be spaced 3 or more meters apart having the sun
azimuth to their backs (if possible). At least 1 set of landing circles shall be provided at a
comfortable walking distance from the distance course for each pilot.

b)

Each round will start with model aircraft in the flight group placed inverted at the launchlocations. The energy state of each model will be ascertained by measuring and recording
the open circuit voltage at the battery balance port. The contest director will announce
launch times at 5 to 15 second intervals for each pilot in the group so as to avoid midair
collisions. A timer shall be used to mark the launch time for each pilot. The helper shallupright and launch the contestant’s model to begin a 400 second thermal loiter and energy
accumulation task. The model may be flown anywhere within the boundaries of the fieldwithin visual line of sight of the pilot/helper. The model may not be flown beyond visual lineof-sight at any time.

c)After the thermal loiter, a distance task is automatically started. The task starts at the Baseclosest to the pilot and concludes 600 seconds after launch. When the model crosses thefirst base after 400 seconds elapses in the direction of the other Base, counting of legs
begins. The model aircraft must complete as many legs as possible from the starting Base to
the other Base and return. There is no restriction on use of motor during this task.

d)After the distance task, a 60-second precision landing task will automatically start. The
objective of the task is to come to rest within the 10-meter circle precisely 660 seconds after
launch. Once the model comes to rest, it must be inverted by the helper within 10 seconds to
end solar accumulation. The battery balance port should be measured in place or the model
removed to a safe location shielding the solar array from additional energy accumulation. If
the model comes to rest in a position/location such that it cannot be inverted within 10
seconds, the flight is scored 0. Alternatively, an approved telemetry-based system may be

SC4_Vol_F5_Electric_24

Effective 1st January 2024

Page 16

Class F5E – Solar Powered Motor Gliders

used to determine the battery voltage at the end of the flight making inverting of the model
unnecessary.
e) The flying order must be arranged in rounds sub-divided into groups. The flying will be arrangedin groups with up to 6 pilots in each group with the number in each group to be determined by
the CD. The general direction of the launch and landing approaches may be set by the Contest
Director prior to launch.
5.5.7.3

Scoringa)Every completed Distance leg will be awarded 10 points.

b)

Precision duration points shall be awarded at the rate of one point/second after 630
seconds. Precision duration points shall be subtracted from 30 at the rate of one
point/second after 660 with no precision points awarded if the total flight time is greater than690 seconds.

c)

An additional 30/20/10 points for landing shall we awarded if the model comes to rest inwithin 30-20-10 meter diameter circles as defined by a tape.

d)

Points shall be subtracted from the score if system energy at the conclusion of the flight isless than at the beginning of the flight at a rate of 1 point per net 3 watt-minutes consumed
according to the formula: (net open circuit voltage loss)*(battery pack nameplate capacity inAh)*20.

e)

The pilot with the most points in each flight group will be awarded 1000 points. The otherpilots will be awarded points according to the formula: (Individual Score/Winning Flight
Group Score)*1000.

General Rules

5.5.11.1.1.

Definition of a Radio Controlled Glider with Electric Motor
A model aircraft which is equipped with an electric motor to provide propulsion only for the
purposes of launching, and in which lift is generated by aerodynamic forces acting on
surfaces which remain fixed (except control surfaces). Model aircraft with variable geometryor area must comply with the specification when the surfaces are in maximum and minimum
extended mode. The model aircraft must be controlled by the competitor on the ground,using radio control. Any variation of geometry or area must be actuated at distance by radio
control. Any airborne device that uses airborne sensors to actuate any control surface areprohibited. Stability systems as allowed in the F5 General Rules 5.5.1.3.e are prohibited.

5.5.11.1.2.

Prefabrication of the Model Aircraft
There is no requirement for the competitor to be the builder of the model. Refer C.5.1.2. in
CIAM General Rules.

5.5.11.1.3.

Characteristics of Radio Controlled Gliders with electric motor and altimeter/motor
run timer (AMRT).
a) Maximum Surface Area 150 dm2
Maximum Flying Mass
5 kg
Maximum wingspan4m
Loading
12 to 75 g/dm2
Type of battery
Any type of rechargeable batteries
Type of motor
Any type can be usedb) Radio equipment not using Spread Spectrum technology to International Standards
must be able to operate simultaneously with other equipment at 10 ΚHz spacing below
50 MHz and at 20 KHz spacing above 50 MHz. When the radio does not meet thisrequirement, the working bandwidth (max. 50 KHz) shall be specified by the competitor.
c) To ensure randomness of the starting order among the successive rounds, competitors
not using Spread Spectrum technology equipment must enter three different transmitter
frequencies with 10 KHz minimum spacing. The Organiser is entitled to use any of thesethree frequencies for setting the flight matrices. Once the competitor is allocated one ofthese three frequencies, he must not change to another frequency for all flights during
the whole of the preliminary rounds other than for re-flights. In case of a re-flight thecompetitor can be called to use any of these three frequencies for this re-flight only, as
long as the call is made at least 1/2 hour prior to the beginning of the re-flight in written
form to the competitor (or team manager where applicable). The content of thisparagraph (c) is not applicable, if the competitor uses a Spread Spectrum technology
system.
d) Any device for the transmission of information from the model aircraft to the competitor
is prohibited. A Spread Spectrum technology receiver that transmits information back to

SC4_Vol_F5_Electric_24

Effective 1st January 2024

Page 20

Class F5J – Electric Powered Thermal Duration Gliders

the competitor-operated transmitter, is not considered to be a “device for thetransmission of information from the model aircraft to the competitor”, provided that the
only information that is transmitted, is for the safe operation of the model aircraft;
i.e. signal strength and voltage of the receiver battery but not any positioning or height
information.
e) The competitor may use no more than three (3) model aircraft in the contest. The
competitor may combine the parts of the model aircraft during the contest, provided theresulting model aircraft conforms to the rules and the parts have been checked before
the start of the contest.
f)

All ballast must be carried internally and fastened securely within the airframe.

g) The underside of the model aircraft must not have any protuberances or arresting
devices (eg bolt, sawtooth-like protuberance, etc) that will cause the model aircraft toslow down on the ground during landing. A folding prop or the tail, including the fin, is
not considered a protuberance or arresting device.
h) Each model must be fitted with an approved AMRT in accordance with the Technical
Specification published in F5J Altimeter/Motor Run Timer Technical Documentation.
The essential functions of the AMRT are:i) To record and display the maximum height attained (Start Height), above aground level reference between the instant of motor start and 10 seconds after
the motor is stopped andii) To restrict the operation of the motor by the competitor to a single continuous
run not exceeding 30 seconds.
iii) To reset the start height displayed to “---” if the motor is restarted at any time
during the flight. In this case (start height displayed to “---”, the result of theflight is 0 and this 0 result can be dropped from total score.
This rule can be used as a local rule at FAI World Cup and Open International
events, but not at Category One events.
i)

Installation of the AMRT in a competitor’s model shall be in accordance with therequirements as detailed in the Technical Guidance Documentation.

j)

Proper operation of the AMRT including any associated display and its compatibility withother control equipment installed in the model is the responsibility of the individualcompetitor.

k) To facilitate initial technical processing, all AMRTs must be easily removable forcompliance checking.
The receiver command signal connection to the AMRT must be easily accessible so thatat any time during the competition the Organisers have the option of installing amonitoring AMRT via a branching Y lead.
To enable the timekeeper to record data required for scoring purposes there must be
easy access to the display or the connector for a plug in display. It must not benecessary to disconnect the AMRT from the receiver and/or the ESC (Electronic Speed
Controller) or to remove it from the model,
The use of an additional extension cable is permitted for connecting the display. It is the
responsibility of the competitor to ensure that any incorrect connection does not result indamage to the AMRT or the display.
l)

5.5.11.2.

Any device other than an approved AMRT which is carried in or on the model and whichenables total or partial independent control over the model’s electric drive motor
operation, is prohibited. Receivers and ESCs are not affected by this rule.

Competitors and Helpersa) The competitor must operate his radio equipment himself.
b) Each competitor is allowed one helper. At World and Continental Championships, whena team manager or assistant team manager are allowed, they are permitted to help thecompetitor.
c) Any use of telecommunication devices (including transceivers and telephones) in the

Page 22

Class F5J – Electric Powered Thermal Duration Glidersb)

To claim a re-flight the competitor must ensure that the timekeeper has noted thehindering condition and must land his model as soon as possible after the event.
If the competitor continues to launch or continues to fly, after the hindering condition
affected the flight, he is deemed to have waived his right to a new Working Time.

c)

A Working Time is to be granted to the competitor according to the following order ofpriorities:i) in an incomplete Group, or in a complete Group on additional launching/landing
spots; orii) in a new Group of minimum six (6) re-flyers. The new Group of re-flyers can bemade up by other competitors selected by random draw. If the frequency orteam membership of the drawn competitor does not fit or the competitor will not
fly, the draw is repeated; oriii) If this is not achievable, then with the original Group at the end of the ongoinground.
iv) In priority-cases ii) and iii), for the competitors allocated the re-flight, the result of
the re-flight is the official score. For the other competitors, the better of theirscore in the ongoing round and the re-flight score will become their official score
Any competitor of this Group who was not the competitor to whom the newattempt was allocated will not be entitled to another Working Time in case ofhindering during the re-flight.

5.5.11.7.

Cancellation of a flight and/or disqualification
The Flight is cancelled and recorded as a zero score if:a) the competitor used a model aircraft not conforming to any item of rule 5.5.11.1;b) the model aircraft loses any part during the launch or the flight, except when thisoccurs as the result of a mid-air collision with another model aircraft. Except thatthe loss of any part of the model aircraft during the landing (coming into contact
with the ground) is not taken into account;c) the model aircraft is piloted by anyone other than the competitor;d) during landing, the nose of the model aircraft does not come to rest within 75
meters of the centre of the competitor's designated landing spot;e) the AMRT does not record any Start Height data.

be awarded a corrected score of one thousand (1000) points for that Group.

m) The remaining competitors in the Group will be awarded a corrected score based on theirpercentage of the Group winner's total score before correction (ie before being
normalised for that Group) and calculated from their own total score as follows:
Competitor’s own score multiplied by 1000
Highest points total scored in the Group before correctionn) Penalties shall be listed on the score sheet of the round in which the infringement(s)occurred. All penalties are cumulative and will be deducted from the competitor’s total
score at the end of the preliminary rounds. Penalties earned in the preliminary rounds
are not carried forward into the fly-off rounds. In case the total score after deduction of
the penalties is negative, a zero (0) score will be recorded. The same total score will be
used for individuals and team classifications.
5.5.11.13.

Final Classificationa) If four (4) or fewer qualifying rounds are flown, the aggregate score achieved by thecompetitor, will be the sum of his scores for all rounds flown. If more than four (4) rounds
are flown, then his lowest score will be discarded before determining his aggregate
score.
b) The CD may elect not to have a fly off. This decision is announced in the invitation or
before the start of the competition.
c) At the end of the qualifying rounds 30% (rounded down) of competitors with the highest
aggregate scores will be placed together in a single Group comprising a minimum of six(6) and maximum of fourteen (14) for the fly-off rounds. For operational reasons the CD
may set a lower maximumd) A minimum of three (3) or maximum of four (4) fly-off rounds should be flown.
Exceptionally the CD may reduce to two (2) in the case of bad weather or poor visibilitye) The Working Time for the fly-off rounds will be fifteen (15) minutes duration. An audible
signal must be given at the start of the Group Working Time and at exactly thirteen (13)minutes and at exactly fifteen (15) minutes. Additionally, the final ten (10) seconds must
be indicated audibly by a countdown.
f)

The scoring of the fly-off rounds shall be as in section 5.5.11.12.

g) Final placing of the competitors who qualify for the fly-off, shall be determined by theiraggregate scores in the fly-off rounds; their scores in the qualifying rounds being
discarded.
h) In the event that two or more competitors have the same aggregate fly-off score, final
positions of those competitors shall be determined by their respective position in thequalifying rounds; the higher positioned competitor being awarded the higher final
position.
i)

The national team classification is established after the completion of the championshipby adding the aggregate scores of qualifying rounds of the three members of the team
together. In the case of a national team tie, the team with the lower sum of placenumbers, given in order from the top, wins. If still equal, the best individual placing
decides.

F5K – RC THERMAL DURATION GLIDERS FOR MULTIPLE TASK COMPETITION WITH
ELECTRIC MOTOR AND ALTIMETER / MOTOR RUN TIMER (AMRT) (PROVISIONAL)
F5K Introduction
The F5K event is a multitask contest where the RC gliders must start and land in a specific“Pilot Area” and perform different flight tasks. The motor stop is controlled by the
Altimeter/Motor run timer device (AMRT: 60 meters, 7 seconds) or by the pilot. A reference
launch altitude is defined before the contest and depends on the wind strength. Goal is to getfair launch altitude for all pilots. However, pilots can gain additional launch bonus points forlaunching lower than the reference altitude. The reference altitude is called the “Nominal
Launch Height” and is 60 or 70 meters.
Each launch is scored with points made up of:• flight time in seconds (may be zero)• launch altitude bonus or penalty points• other penalties (if applicable)
One point will be awarded for each full second of flight within the Working Time. If the total of
all points is negative, the score is zero (0). The score is the accumulation of the flight times,
adjusted for penalties and bonuses for launch altitude and any other penalties (if applicable).

5.5.10.2

Task overview
General: test flying is only allowed before the contest and during the break.
Task A: 1, 2, 3, 4 minute flights in any order• All pilots must launch simultaneously at the start of the signal• Four launches maximum• 1, 2, 3 and 4 minutes target times, flown in any order within a 10 minute window• Each flight counts even if the target time is not achieved• Maximum total flight time used for scoring: 9.59 min.
• After 10 minutes the pilot will have 15 seconds to land
Task B: Last Flight 5 out of 7 minutes• All pilots must launch simultaneously at the start of the signal• Three launches maximum• Working time is 7 minutes• Only the last flight counts• The maximum flight time is limited to 5 minutes. Any subsequent launch of the model glider
annuls the previous time. It is allowed to overfly the 5 minutes target time
• There will be a launch penalty in case a pilot uses more than 1 launchFirst launch: no launch penalty – zero penalty points
Second launch : launch penalty is 10 points
Third launch: additional launch penalty of 10 points (20 points total penalty)
The number of flights is registered on the scorecard• After 7 minutes the competitor will have 15 seconds to land.
Task C: All up, 4 minutes maximum (3x)• All pilots must launch simultaneously at the start of the signal• Working time is 4:01 minutes• Three flights of 4 minutes maximum. The maximum measured flight time is 4 minutes
during each All-Up task.

Task D: 3, 3, 4 minute flights in any order• All pilots must launch simultaneously at the start of the signal• Three launches maximum within a 10 minute window• 3, 3 and 4 minutes target times, flown in any order within a 10 minute window• Each flight counts even if the target time is not achieved• Maximum total flight time used for scoring: 9.59 min.
• After 10 minutes the competitor will have 15 seconds to land.
Task E: Poker• All pilots must launch simultaneously at the start of the signal• Working time is 10 minutes• Each competitor has a maximum of three launches to achieve up to three self-nominatedtarget times within the working time
• The target and maximum allowable flight time is 9 minutes and 59 seconds• The pilot can announce “all in” for his first launch. Only one launch is then allowed.
• Before the first launch of any new target, each competitor announces a target time to thetimekeeper. The timekeeper records the nominated target time on the score card
• The pilot can any use remaining launches to try to reach his target time up until the end ofworking time
• If the target is reached (or exceeded) the timekeeper will mark the flight with “Y” (timeachieved). The pilot is credited with the target time. Any time over the target time is notcounted• The launch altitude bonus or penalty only applies only where the target time is achieved. If
the pilot has unused launches, before launch he must announce the next target time (less,more or “end of working time”) to the timekeeper• The timekeeper writes this against the next flight number on the scorecard and the pilot
takes his new launch• Only one attempt is allowed if the pilot announces “end of working time”• If the target time is not reached, the timekeeper will mark the flight with “N” (not achieved).
The launch bonus or penalty does not apply where the target time is not achieved. While
the pilot has unused launches, the target time remains the same for the next launch. The
timekeeper writes this target time against the next flight number and the pilot takes his
new launch• Flights with achieved target times are scored, adjusted for height, bonus or penalty,
landing out of the pilot area and any flight penalties• Launch penalty applies whenever a launch is made. The launch penalty applies even if theflight fails to achieve the target timeFirst launch: no launch penalty – zero penalty points
Second launch : launch penalty is 10 points
Third launch: additional launch penalty of 20 points(30 points total penalty)
The number of flights is registered on the scorecard• After 10 minutes the competitor will have 15 seconds to land
5.5.10.3

Nominal Launch Height (NLH)
The Nominal Launch Height is the reference launch altitude (NLH) in which there are nobonus or penalties applied and is set in a competition software program (for example
Gliderscore). Pilots can gain bonus points and launch under the NLH or get launch penalty
points by launching over the NLH. The NLH is related to the strength of the wind. For lightbreeze wind the NLH is 60 meters. For moderate wind speed the NLH is 70 meters. One day
before the start of the competition, the Contest Director will announce the Nominal Launch
Height for the competition day. For this he will take the average wind strength between 11h
and 17h.

Launch points related to the NLH
The launch altitude is the highest altitude reached from launch until 10 seconds after the
motor is stopped. There will be no bonus points for flights shorter than 30 seconds, penalty
points still apply.
Penalty or bonus points only apply to valid flights.
Bonus and penalty table:
For each meter under the NLH: 0.5 points per meter bonus applies.
For each meter from 1 to 10 meter over the NLH: 1.0 points per meter penalty applies.
For each meter from 11 meter over the NLH: 3.0 points per meter applies.
The bonus or penalty points are always calculated with reference to the announced NLH.
Launch altitudes are shown on the AMRT (fe Altis nano). The NLH bonus and penalty table
are set in the competition software (fe Gliderscore), which translates the launch altitude tobonus or penalties points.

5.5.10.5

Launch and Start flight time:a) The Contest Director will announce the preferred direction of launch. Pilots always need tolaunch against the wind direction, even if this is not the preferred announced launch
direction. However, it is not allowed to launch over the pilot area of other pilots. Thereforlaunches are in the preferred launch direction or 180 degrees other than the preferred
launch direction.
b) The AMRT is activated before the start of the working time with the model glider still on the
ground to set the zero meter offset correct.
The AMRT records and displays the maximum altitude attained (Launch Height), above aground level reference between the instant of motor start and 10 seconds after the motor is
stopped. It restricts the operation of the motor by the competitor to a single continuous run
not exceeding 7 seconds. It resets the start height displayed to “---” if the motor is restarted
at any time during the flight. Each model must be fitted with an approved AMRT in
accordance with the Technical Specification published in F5J/F5K Altimeter/Motor Run
Timer Technical Documentationc) The flight time starts at launch, meaning the moment the model glider is released withmotor running from the helper or competitor’s hands, not at the start of the acoustic signal.

Reflight
In case of a mid-air collisions of two or more model gliders the competitors will not be granted
refights nor will penalties be applied.
The competitor is entitled to a re-flight if:i) if his attempt could not be performed correctly due to organizers fault. The new working timeis to be granted to the competitor according to the following order of priorities: a) in a following
group; b) if this is not achievable, then in a new group of a minimum of 4 re-flyers. The newgroup of re-flyers can be completed by other competitors selected by random draw. If thefrequency or team membership of the drawn competitor does not fit or the competitor will not
fly, the draw is repeated; c) if this also is not achievable, then with his original group at the endof the ongoing round. In b) and c) above the better of the two results of the original flight andthe re-flight will be the official score, except for the competitors (re-flyers) who are allocatedthe new attempt. For those, the result of the re-flight is the official score. A competitor of thisgroup who was not allocated the new attempt will not be entitled to another working time incase of an organizer’s faultii) the launch altitude was not recorded in the AMRT and / or the associated external AMRT
software could not determine the launch altitudeiii) the attempt has not been judged by the timekeeper, provided that the helper or the pilot
has informed the timekeeper about the position of the model a reasonable time before
landing; if this is not done, the competitor is not entitled to a re-flight if his attempt has notbeen judged by the timekeeper.

5.5.10.14

Preparation timeFor each round, the competitors receive at least 5 minutes of preparation time.

5.5.10.15

Scoring
The scores are normalized within each group, 1000 points being the basis for the best scoreof the winner of the group. The result of a task is measured in points and truncated down to
the whole points. The normalized scores within a group are calculated by using the following
formula: normalized score (points) = competitor’s result (points) / best competitor’s result(points) x 1000.
The normalized scores are rounded to whole numbers (points).

5.5.10.16

Final score
The final score is the sum of the normalized scores of all rounds. If seven (7) or more rounds
are flown then the lowest score is dropped. Basepoint to determine the final results are thescorecards signed by pilot and timer. Rectification of the final result is only possible if theorganization has incorrectly processed the approved score cards (flight time, launch altitude
and other bonuses and/or penalties). Other data than signed scorecards will not be accepted
to determine the score result.

5.5.10.17

Resolution of a tie
In the case of a tie, the best dropped score defines the ranking. If the tie still exists, a separate
fly-off for the relevant competitors will be flown to achieve a ranking. In this case the contest
director will define one task that will be flown for the tie-break fly-off.

5.5.10.18

Fly-off
The organizer may announce a fly-off prior to the beginning of the event. For World andContinental Championships, the fly-off is mandatory for seniors. The fly-off should consist of atleast three (3) rounds with a maximum of six (6) rounds. If less than three (3) fly-off rounds
can be completed, the result of the preliminary rounds determine the final ranking. A junior flyoff may be held with the maximum number of competitors being 2/3 of the seniors fly-off. A
separate junior fly-off is not mandatory. If a fly-off is flown, the points of the previous rounds
are not considered for the final score.

5.5.10.19 Team Classification
To establish the ranking for international team classification, the final individual scores of thethree best members of the team are added together. Teams are ranked according to the highest
numerical score to lowest. In the case of a national team tie, the team with the lower sum of theplace numbers, given in order from the top, wins. If still equal, the best individual placing decides.

5.5.12 CLASS F5L – RADIO CONTROLLED THERMAL GLIDERS RES WITH
ELECTRIC MOTOR AND AMRT (PROVISIONAL)
5.5.12.1

General Rules
F5L is a class for radio-controlled 2-axis gliders with an electric motor and a logger.
F5L class is similar to F3L one and differs only by the starting procedure with an electric motor
instead of a bungee.
The models feature a maximum two (2) meter span, are primarily of wooden construction andare controlled by rudder, elevator and spoiler(s). For launching, the electric motor may run 30
sec. Due to the restrictions on construction and equipment, it will be possible to participate incompetitions at low costs and with average skills. One key aspect of this class is to inspireyoung modellers and integrate them into the sport. The rules that follow shall be understoodand interpreted with this in mind.

5.5.12.2

Definition of a Radio-Controlled Glider
A model aircraft whose lift is generated by aerodynamic forces acting on surfaces remaining
fixed. In F5L class, the electric motor serves only for the launch.
The competitor must control the model from the ground using radio control.

5.5.12.3

Model Specifications for Radio Controlled Thermal Gliders F5L
A model typically consists of wings, fuselage and tail. Flying wing models that do not have afuselage and rudder or vertical stabilizer or none of these components are also allowed if they
have only two (2) control surfaces. Each of these surfaces has to be actuated by only one
servo. Otherwise, the construction rules for conventional models described herein are
applicable.

5.5.12.3.1 The model is built mainly with wooden parts. The following methods are permitted:a)Wings built with ribs, open or covered by wood, „D-box“, solid wood wings or a
combination of solid wood and ribs.

b)

All parts must be made from wood except for the leading edge, spar(s) and connecting
parts of the wing panels and the motor mount frame.

c)

The surface of the wings may be covered by film, silk, paper or polyester fabric.
Specifications a) to c) are applicable to the tail planes too.

d)

The space between the rear edge of the spoilers and the trailing edge must be at least 5
cm. One or two servos may activate the spoilers.

e)

The fuselage must be made entirely from wood or with a tail boom made fromfiberglass/carbon (GRP/CFRP), Kevlar tube, or profile. The tube/profile must not extend
the front half of the wing area.

f)

The wooden surface of the fuselage may be covered with fiberglass/carbon (GRP/CFRP)
or Kevlar, but not more than a maximum of 1/3rd of the total area. The surface may beprotected with varnish or like described in c).

g)

Hinges and control rods are exempted from the GRP/CFRP constraint.

h)

The selection of the electric motor is free.

g)

The selection of battery is free

5.5.12.3.2 Not allowed is the use ofa)positive or negative molds for construction of the fuselage or wings or the surface
treatment.

b)a fixed or retractable arresting device (i.e. bolt, sawtooth-like protuberance, etc.) to slow
down the model on the ground during landing. The underside of the model must not haveany protuberances.

e)

any telemetry except for radio signal strength, receiver temperature and battery voltage.
No variometer is permitted.

f)

any telecommunication between competitors and helpers, including mobile phones orwalkie-talkies.

5.5.12.4 Description of the Competitiona)

In competition, at least four (4) qualifying rounds shall be flown. For each qualifying round,participants shall be divided into flight groups. The results of each flight group shall benormalized to arrive at comparable scores between the flight groups. The highest scorewithin each flight group will be assigned 1000 points, and the remaining scores within thatgroup shall be proportional to each participant’s raw flight score relative to the best raw
flight score within that group. The group size in the “Fly-Off” shall be the same as in the
preliminary rounds. Participants flying with the highest total normalized scores from thepreliminary round will compete in a “fly-off” (minimum 2 rounds) to determine the finalclassification.

b)

The competitor may use three (3) models in the contest. The competitor may change
models at any time, but within a round only if the model used first is placed within a radiusof 15 meters of the assigned landing spot.

c)

The competitor may use up to two (2) helpers. These assist him in launching and retrieving
the model, informing him of weather conditions and flight time and managing the start.

d)

The organizer should have official scorekeepers/timekeepers available. If this is not thecase, the pilot’s helper will keep time, and the organizer will regularly sample the flighttimes. Deviations of more than three (3) Seconds in favour of the participant shall lead to azero-score flight.

5.5.12.5 The Flying Sitea)

The competition must be held on a site having reasonably level terrain, which will minimise
the possibility of slope and wave soaring.

b)

There must be marked start/landing spots for each competitor at least eight (8) metersapart. Take-off should happen within two (2) meters of the assigned start/landing point.
This rule also applies when starting again.

c)

The distance between the fuselage nose and the landing point will be measured by a tapeor string, which may be fixed at the landing point.

d)

The Contest Director shall determine the landing boundaries. Landing outside theboundary shall result in a zero score for that flight. (see also 8.2).

5.5.12.6 Interruptions

5.5.12.7a)

The contest director can interrupt the competition and reset the start/landing points.

b)

The contest shall be interrupted by the contest director if the weather conditions for themodels are no longer reasonable.

Launching
Starting is after the beginning of the working time with the electric motor running.
For designs that do not permit a safe start with the motor running (e.g., wing-mounted aircraftwith rear-mounted motor), the motor is switched on as soon as possible after the launch, andthe time begins when the motor is switched on.
The motor runtime (30 sec) and the starting height (90m) are limited by an EDIC-approved elogger (e.g., Altis V4, Altis V4+, Altis Micro, Altis Nano etc). The organizer should check thesettings of the AMRT before the competition. The organizer can check the AMRT at any timeafter a flight. The flight is recorded as a zero score if the settings differ from the pre-sets.

The competitor is entitled to at least four (4) official flights.

b)

The competitor is entitled to unlimited attempts during the working time.
Before restarting, the flight battery must be briefly disconnected from the controller to reset
the AMRT.

c)

An official attempt begins when the model leaves the hand of the competitor or his helperwith the electric motor running.

d)In case of multiple attempts, the result of the last flight will be the official score.

5.5.12.9 Re-flights
The competitor is entitled to a new working time if:a)his model in flight or in the process of being launched collides with another model flying or
being launched.

b)

When his flight is hindered or aborted by an event beyond his control.

To claim a re-flight considering the conditions mentioned above, the competitor has to makesure that the official timekeepers have noticed the hindering conditions and land his model assoon as possible after this event.
Note that if the competitor continues to launch or fly after hindering conditions affecting his flightor does a re-launch after clearing the hindering condition(s), he is deemed to have waived his
right to a new working time.
5.5.12.10 Landinga)Each competitor will be assigned a start/landing spot before each flight. The competitor
shall be responsible for using the correct assigned landing spot.

b)

During the landing process, only the pilot and his assistant are allowed within 10 meters of
the landing spot. Any other helpers and timekeepers shall stay at a distance.

c)After landing, competitors may retrieve their model aircraft before the end of their working
time, providing they do not impede other competitors or model aircraft in their group. A
model thus retrieved may be relaunched during the working time. No landing score may berecorded for a model touched before scoring the landing.

The maximum flight time is 6 minutes and 30 seconds (390s) within nine (9) minutes (540s)
working time. The flight time will be recorded in full seconds. If the flight is longer than (6:30)
minutes (390s), the overflying time will be deducted from (6:30) minutes (390s). Each second offlight time will be scored two (2) points. The highest score within each flight group will beassigned 1000 points, and the remaining scores within that group shall be proportional to eachparticipant's raw flight score relative to the best raw flight score within that group.

c)the model is overflying the group's working time.

d)the model touched the competitor or helper during the landing.

e)the competitor or helper touched the model before the official scorekeeper made thedistance measuring.

Zero points for the entire task (flight and landing) are awarded if:a)

The model rests outside a landing area as defined by the organizer. Within the working
time, the competitor may launch for another attempt.

b)the model is overflying the working time for more than 30 seconds.

5.5.12.12 Final Classification
If five (5) or fewer qualifying rounds are flown, the aggregate score achieved by the competitor
will be the sum of his scores for all rounds flown. If more than five (5) rounds are flown, hislowest score will be discarded before determining his aggregate score.
For competitors who qualified for the fly-off, the final ranking is determined by the ranking at the
fly-off; for other competitors, the ranking is done by the ranking at the qualifying rounds.
