## Introduction

WARNING : To avoid injury, read all operating instructions and watch all online training videos before flying

A small unmanned aircraft is defined in the ANO as any unmanned aircraft weighing not more than 20 kg. A set of conditions are included at Articles 166 a nd 167 of the ANO subject to which small aircraft may be flown without complying with airworthiness or flight crew licensing requirements or with the Rules of the Air. These conditions include a prohibition on flight in controlled airspace or within an aer odrome traffic zone unless in either case the permission of the air traffic control unit has been obtained, a normal maximum height of 500ft above the surface and a prohibition on flight for the purposes of aerial work without the specific permission of CA A. Article 167 specifically covers the use of small unmanned aircraft for surveillance or data gathering.

All Lehmann Avi ation L

- A Series drones are classed as light Unmanned Aerial System (UAS) for capturing low level aerial images. They must be operated in accordance with the Civil Aviation Authority regulations of your country. All L

- A Series drones are certified by the French Aviation Authorities (DGAC) for the flight scenario S2+.



## Setting up aircraft

WARNING : Do not mount the Electronic part to the wing before the 5 seconds BEEP signal,
that will confirm s that GPS satellites have been correctly fixed by the auto

- pilot

WARNING : Always be careful with the propeller while manipulating the aircraft with the battery connected . Make sure you keep the propeller far enough from your own fingers or from any person around7

WARNING : Never use L

- A Series aircraft without mounting a GoPro camera in oblique or vertical position (Hero3 and upper only) . Wh ile using the vertical position mount for GoPro,

Canon or MicaSense camera, it is compulsory to mount a 50grams weight at the place of the oblique camera mount (upper front of the wing), for balance purpose

WARNING : Always use a fully charged battery before each flight of L

- A Series aircraft . Do not accomplish 2 take

- off with the same battery without re

- charging it

F ollow this p rocedure to set up your aircraft (quick launch procedure):

How to assemble the aircraft

1 . Mount the camera in oblique or vertical position

- in vertical position, the balance weight should be in place in t he front upper part of the wing (at the place of the oblique GoPro mount):

2 . Put your gloves on (right or left) to p rotect your fingers from the propeller at take

- off8

3 . Connect on board battery : battery cable must be positioned as shown on the photo
below. N ever mount the battery on the opposite side (with the cable going initiall y to the front of the aircraft). Here is the good position of the battery and battery cable:

Once the battery is connected , the black part must be always kept horizontal

. Do not move it
too fast till take

- off in order to let the sensors calibration.

We strongly recommend to let the part on a stable place after you connect the battery (like the ground or any table) where it will not move during OperationCenter connection and test procedures.

4 . Connect your aircraft WiFi (LA200 or LA300 network) to your Tablet :

- go on the “Settings” options o n the right side of your screen9

- and then click on the WiFi connexion icon. Default password is “ password ”

5 . Open OperationCenter software

6 . Click on the “Enable WiFi” button ( “ Connexion Successful ” should appear . If not try again )

7 . Go to the SYSTEMS page to check the aircraft systems (artificial horizon, GPS fix, date and time) :10

Before going to the next step, wait for the GPS Fix (a 5s BEEP will come from the aircraft, the red circle will disappear from the artificial horizon and GPS coordinates will appear on the screen) . GPS fix will be possible outside only . It will not fix inside offices, houses or
apartments.

- double check if the artificial horizon is moving well in the same direction when you are moving the black part. You can also check the heading at this point.

8 . Go to the NAV page and upload your flight path to the drone by pushing on the “Import/Export” and “Send by WiFi” buttons (you can create a new one if needed):11

9 . Go to the FLY page

10 . Mount the aircraft to the wing : be careful to put the battery cable inside the wing, and
do not let it outside as it may result in a poor efficiency of the Velcro attachment

- correct mount :

- incorrect mount :12

- to have the black part and the wing assembled, you should “mount” the wing on the black part. That means while always keeping the black part horizontal, you must place the wing on top of the black part and not vice versa

- after “mounting” the wing on the black part, make sure that they are well aligned (keep the aircraft horizontal during this process).

- correct alignment:

- incorrect alignment :

11 . Check the 2 ailerons by tilting the aircraft 60° DOWN: the 2 ailerons must move in opposite directions on a continuous basis. Your aircraft is now ready for take

- off

WARNING : If 1 aileron doesn’t move correctly, you will have to do again all the setup sequence. If the aileron is still not working after few attempts , then you will have to change your wing. NEVER fly with an aileron malfunction.13



## Drone U pdate procedure

WARNING : Don’t update your system just before an important operational mission. Always make a test flight after updating your drone before launching an operational mission.

WARNING : Always make an update with a fully charged battery. Don’t disconnect the battery during the update process as it could needs your drone to be shipped back to the factory to make it run again.

Update procedure

1

## Flight Preparation

WARNING : Pre

- flight preparation is essential in ensuring a safe flight

Flight preparation:

 Require specific authorizations if needed (from field owner and /or Aviation Authorities)

 Check weather conditions (1 to 3 days before operations and again the day of flight)

 Charge all batteries (aircraft

, camera , t ablet /PC ) and check all system s before leaving

Pre

- Flight planning 1. Select a safe operation area (tall objects like trees or antennas must not be on the way of
take

- off and landing)

2. Sele ct a safe landing area (L

- A S eries aircraft can land on most of the surfaces but it is best to avoid rough surface to prevent damage . Do not land on water)

3. Check wind direction and always take

- off and land FRONT WIND . Otherwise, L

- A S eries
aircraft might not have enough power to climb properly during take

- off, or can be damage d at landing18



## Before Take

- off

WARNING : Those checks are absolutely imperative in order to fly safely

Before tak e off

1. Connect the battery and let the aircraft horizontal and stable until take

- off 2. Switch ON your Windows8 .1 device and connect to the aircraft via the Wi

- Fi connection. Your aircraft network should appear with its model version identification (LA200 or LA300)

. Enter the default Password: “password” 3. Open OperationCenter and then activate the “Enable Wi

- Fi” button

4. When you have seen the PopUp “Connexion Successful”, g o to the “ SYSTEMS ” page and

w ait for a 5 second s BEEP (that will indicate that GPS satellites have been fixed. During this phase, always keep the aircraft horizontal). The BEEP can come between 20s and 3 minutes.

5. C heck all your aircraft systems : Artificial horizon (should move with the aircraft), GPS (should be in GREEN, 3D), and Date and Time (UTC)19

6 . Go to the “ NAV ” window, prepare or load a saved flight path and then “ Send via Wi

- Fi” the flight path to the aircraft

. By pushing few times on the NAV button, you will change from “Free flight” to “Mapping” mode (only for LA300 and LA300AG)

7 . Always double check the flight path in the Drone by “Clear Path” and “Confirm”, then “Import/Export” and “Load from WiFi” the flight path that is in the drone memory20

8 . Go to the “ FLY ” page

9

. Mount the aircraft to the wing, as shown on the training video (see also the Getting Started section of this Manual)

10

. Before launching the aircraft, c heck again the Artificial Horizon ( muqt move with the aircraft) and the battery level ( must be full). Click on the Battery icon to see the precise voltage of the battery (should be more than 12.5V)21

11

. When ready, t ilt the aircraft 60° DOWN. You should observe the 2 ailerons moving on the opposite direction

WARNING : If 1 aileron doesn’t move correctly, you will have to do again all the setup sequence. If the aileron is still not working after few attempts, then you wil l have to change your wing. NEVER fly with an aileron malfunction.



## Take

- off

WARNING : Never take off with the battery not totally charged

WARNING : In order to avoid finger injury, always wear the protection glove and keep

concentrate d during the launch process. The initial straight impulsion must be a s shown on the training videos

L

- A series aircraft are hand

- launched aircraft (watch the online training video s ).

Take off procedure

1. Hold the aircraft with your 2 fingers in the h o l e s of the black part , with a straight arm

2. Tilt the a ircraft 60° UP

. You will hear a BEEP and after 10s the engine will be started 3. Check that ailerons are coming automatically to neutral position (just after tilting the
aircraft 60° UP ) , and stop moving continuously22

4

. Before the engine start s , prepare the aircraft with nose 1 0 / 15° UP
5. Launch the aircraft by transmitting energy to it (like shown in the training video) , keeping your arm straight

WARNING : You can stop the process any time by tilting the aircraft DOWN 90°



## During the flight

WARNING : Always monitor the aircraft during the flight in order to be able to recover it easily in case of aborted flight . If the aircraft for any reason goes below 50 meters of height,
it will make a BEEP and the engine will stop for security reason (15m when “Allow low Altitudes” is selected in the General Settings option)

After the launch you will have around 4

- 5 minutes before the aircraft will land automatically if you don’t activate the mission ( LA200/LA300) . During this time L

- A Series aircraft follows a

set

- up trajectory at 100 meters height and around 200m radius to capture the best footage around you.



## Launching the mission

For security reasons, if you are not doing any action after take

- off , LA200 and LA300 will automatically follow the LA100 flight path, with a 200m radius circle, and land automatically
after 4 minutes 50 seconds of flight time.

To enable the aircraft to activate its flight path ( the one that is on the NAV screen of Operat ionCenter) and let it go to the first waypoint, follow this procedure:

Go mission procedure

1. Always be on the FLY page when launching the aircraft.

2. At any time between the take

- off and the 100m altitude, you can CANCEL the mission INSTANTLY by clicking on LEFT AND RIGHT “CANCEL MISSION” button s AT THE SAME TIME. If you are cancelling the mission, the aircraft will stop its engine and will come back to land by gliding near t he take

- off point. If you are clicking only on one button (left or right), the
mission will not be cancelled.23

2. When the aircraft reach es 100m height, the “GO / CANCEL MISSION” butt ons will appear on the FLY page

3

. To launch the mission, just click on the “GO / CANCEL MISSION” buttons AT THE SAME

TIME ON BOTH SIDE S of the screen (quick click)

4 . You can also CANCEL the mission anytime by clicking 2 seconds (continuously) the “GO /

CANCEL MISSION” buttons AT THE SAME TI ME ON BOTH SIDE S of the screen.24

WARNING : Once you confirm the mission, you will not be able to interact with the aircraft anymore until the end of the flight , unless you have a long range antenna



## Landing

L

- A series aircraft can land by circling over the landing point, or by flying a straight in approach. To choose between the 2 landing options, just follow this procedure:

Landing option procedure

1

. Default landing option is by Circling and gliding over the Landing point. In that case, the landing point is showed on the NAV page by a “L” indication. Your aircraft will stay at the Altitude of the last waypoint and fly overhead the “L” waypoint before s topping the engine and glide until reaching the ground

2. If you want to choose a straight in approach, click 2 seconds on the “L” point. There will be a new waypoint appearing on your screen at the same time. The 2 waypoints will be named “LS” (begin ning of approach point) and “LE” (landing point)25

3. Move the “LE” waypoint to land precisely where you want (usually done just on the field when you see your exact position on the screen) and then move the “LS” waypoint on the

circle to define the direction of the straight in approach (the direction will be defined both by obstacles and by the wind direction the day of your flight). Always land front wind (same

as take

- off)

WARNING : Make sure that the landing area is safe before aircraft touches the ground , with no people around



## After landing

After landing checks

1 . Monitor the whole aircraft for possible damage (wing, propeller, protection foam, etc...)

2

. Disconnect the battery 3. You can also upload the flight path information to compare the real flight path with the

prepar ed flight path of the aircraft 4. To proceed, close OperationCenter and re

- connect the aircraft battery 5. Open OperationCenter again and activate the “Enable Wi

- Fi” button

6. Go to the LogBook page26

7. Upload the Real Fl ight Path via Wi

- Fi and save it (you must have create d a pilot name before) 8. Erase Memory to accelerate future uploads (if you don’t RESET MEMORY after uploading data, you will have to upload all flights data after your next flight, which will take more time) 9. When launching the Erase Memory procedure, always wait 2 minutes (or when the PopUp confirmation will appear on the screen) before disconnecting the battery

In case of damage, m ake sure to properly fix them before flying again.27



## Sensors calibration

WARNING : Sensors are essential for autopilot and you will have to re

- calibrate them when needed. At set up, aircraft will make a 1s series of BEEP when calibration have to be done

. You can also do it on a regular basis when heading accuracy is becoming low.

WARNING : In order to get a good pre

- flight sensors accuracy, it is essential to keep the aircraft as horizontal and stable as possible from the battery connection and up to take

- off.

WARNING : In order to avoid any in

- flight sensors perturbation, it is essential to place the battery and battery cable in the good position, as shown in the “Getting Started” section of

this Manual.

WARNING : For magnetometers only, calibration should be made outside, in a flying area, with wing in place and camera ON (aircraft ready to fly).

Sensors calibration is done in 3 steps:

 Accelerometers calibration (aircraft must be perfectly stable and horizontal)

 Gyroscope calibration (aircraft must be perfectly stable during the process)

 Magnetometers calibration (aircraft must be moved in all 3D directions during the process)28

Sensors calibration procedure 1. Connect the battery to the drone

2 . Open OperationCenter and then activate the “Enable Wi

- Fi” button

3 . When you have seen the PopUp “Connexion Successful”, go to the “SYSTEMS” page

4 . Then you can engage the sensors calibration, one by one. Follow the procedure that will appear in a PopUp menu for each calibration29

## GeoRef images

The GeoRef page will enable you to Geotag images when necessary if not already done in the camera during the flight.

GeoRef will enable you to save GPS data (ALT/LONG/LAT) in EXIF file s (directly in the photo files) and also the attitude information (YAW/ P ITCH/ROLL) in an external file usable with Agisoft or Pix4D.

GEOTAG procedure before processing images in a DEM software

1

. Before opening OperationCenter, put in the same folder all your images AND the flight data file (.lal file).

2. Erase ALL the images taken before take

- off . As the synchronization is done when the ENGINE is going full power at take

- off , you have to erase all images taken before that. Usually, it will only stay few images showing your hand on it, just before releasing the
aircraft for take off 3. Open OperationCenter 4. Open the GeoRef page and select the folder with both images and flight data file 5. Export to “EXIF” first

After exporting data to EXIF, you can proceed with a photo selection in order to erase all

unn ecessary images. That will save you a lot of post treatment time, and increase the accuracy
of the final result.30

Selecting images

1

. Push on the “ Photo Selection ” button (appears only when you have already done the Export to EXIF) :

2. Select manually the photos to erase (just by touching them on the screen) 3. You can block the selection to move the map when necessary by clicking on the “Enable map control” button:

4. Then confirm the Erase of the images that will be erased only from the “Georeferenced” image folder (note that all un

- geotaged images will be still available for future treatment if necessary)

.31



## Replay a flight and data analysis

You can replay a flight with a .lal file in the Replay page, or directly in the LogBook when the flight has already been saved.

Replay a flight in the Replay page

1

. Open OperationCenter 2. Go to the Replay page32

3. Load a flight data file

3. Add a scenario to compare the real flight to scheduled flight33

4. Check the battery level: by clicking a second time on the Alt Graph icon, you will see the battery level evolution during your flight. That can be useful to analyse your battery life and potential:



## LogBook Management

Using the LogBook will enable you to manage your flight time as drone operator, manage your
batter y life and your aircraft.

It will also allow you to instantly get all information on one specific flight: flight data and scenario, remarks and all other useful information (date, location, aircraft, flight time, etc...).

WARNING : Save a backup of your LogBook on a regular basis in order to avoid any data loss.

Importing flight data

1

. Connect a battery to your drone and connect the WiFi network

2. Open OperationCenter and “Enable WiFi”

3 . Go to the LogBook page34

4. OperationCenter will automatically propose you to import flight data (only if you have already created an Operator)

5. When reaching 100%, just save your .lal file on your computer

6. When proposed you can save other flight inf ormation or “Close” the windows (i f you “Close” the windows without saving information, you will have to use the Replay page to open your flight data file )

7 . Op erationCenter will propose you to Delete the drone memory after the import. You can also “Erase memory” later in the SYSTEMS page.35 

# Emergency Procedures 

# 6

Read this chapter to learn about L

- A Series aircraft emergency procedures

.



## Introduction

WARNING : In case of emergency during a flight , always report to the manufacturer in order

to take needed corrective actions



## Cancel Mission procedure

In case of possible conflict with any other aircraft or technical problem

, the CANCEL mission button(s) will allow you to stop the engine immediately and let the aircraft glide in the direction of the launching point.

To activate the CANCEL mission option, just proc eed as follow:

- During the Take

- off or Landing phases: press once on the CANCEL mission button(s) and the procedure will be engaged immediately

- As soon as the Mission become available and until the Landing phase: push the CANCEL mission button(s) for 2s a nd the aircraft will stop its flight



## Horizontal Distance Failsafe procedure

In case the aircraft is pushed by the wind outside the No Fly Zone , the engine automatically

shut s down and the aircraft engage s an Auto

- Return mode , in order to take the direction of the launching point.

WARNING : If the aircraft come s back with engine OFF, it will mos t probably land before the
take

- off point. In that case, take a visual landmark (tree, antenna, house, etc...) to find your
aircraft quicker

. The aircraft will keep beeping until the battery is too low . The use of an external GPS tracker is also recommended in case of long range flight.36



## Height Failsafe procedure

If the aircraft for any reason goes below 50 meters of height (in reference to the launching point) , it make s a BEEP and the engine stop s for security reason

. This safety is 15m when the “Allow Low Altitudes” option is activated in the General Settings options.

This safety is unavailable when the “Allow Negative Al titudes” option is activated in the General Settings options.

If the aircraft for any reason goes above 150m of height (in reference to the launching point), it makes a BEEP and the engine stops for security reason. It will continue to follow the mission when the aircraft will go down the safety height. The safety height will be 1,0 00m when the “Allow High Altitudes” options is activated in the General Settings options.



## GPS Failsafe procedure

In case the GPS is not p ossible to be fix ed before launching the aircraft, it will be impossible
to activate the take

- off mode.

In case of loss of GPS signal during the flight, the autopilot aut omatically shuts the engine off
and the aircraft glides in circles till landing
