Each contestant will be allowed three
official flights In each event. A fight of
less than five seconds will be a delayed
flight" and will not be scored. If the
contestant desires, fight accidentally
interfered with by officials or others or
checked by being caught in the ceiling
lights at Mcfarland will be considered
a delayed flight" Three delayed flights
will count as an official fight. The
same or different planes may be used.
The best flight only scores for points,
except in case of tie. when second fight
will determine winner
All planes must be made and operated
by the contestant. If, in the opinion of
the judges, special conditions warrant,
substitute may be allowed to operate
a plane. In addition to raw materials,
contestants are allowed to purchase, in
finished form only, bearings, propeller
shaft, small metal fittings and wheels.
For planes with power other than rub
Der (dynamic), contestants are allowed
to purchase spring motors, compressed
air motors. tank outfits and other motor
devices. All floats and propellers must
be made by contestant.
Dynamic models must be equipped
with one or more propellers, wings and
fuselage. This requirement is intended to
eliminate entries that are obviously not
aircraft. Rockets are especially barred.

A|RPLANE STUDY
Automotive Technicians viii
Take Up Plane Problems
at Chicago Meet.

Some of the most important problems
facing the aeronautical industry today
will be taken up for discussion during
six technical sessions of the Society OF
Automotive Engineers to be held Au-
gust rs, q and % in Chicago IN con-
nectiOn with the National Air Races, II
has been announced here. Omclals OF
the National Advisory Committee for
Aeronautics from this city will take
prominent part in the sessions.
One OF the sessions will be devoted
to airplane spins in all their phases,
causes and methods of prevention. DR.:
George w. Lewis, research director OF
the N. A. G. A. will preside and papers
will be presented by such we'll known
engineers as Paul. z. Hovgard OF the
Keystone Aircraft Corporation: Harry
A. Sutton of the Aviation Corps; Gar
land P. Reed, jr., we'll known test pilot;
Temple Joyce Of the Berliner-Joyce
Aircraft Corporation, and Fred E.
Weick of the National Advisory Com
mittee for AeronauticS.
Similarly, q session will be devoted to
the discussion of the essential charac-
teristics of aircraft fuels. This subject
is today a moot question on which au-
thorities differ and will be treated by
representatives of air transport lines, en-
CINE manufacturers and fuel producers.
1t is anticipated that from this discus
sion will come much information that
will enable definite steps to be taken
to assure progress.
Aircraft engines will be discussed in
two papers from the angles of cost and
design, particularly as compared with
automobile powerplants. j. w. Crowley,
jr., of the National Advisory Committee
for Aeronautics, will present a paper on
Flight Research" which will give the
results of the work done by this organ
ization in recent months. The remainder
of the program will treat of aerodyna-
mic matters and problems Of structural
design.

TWO-WAY RADIO PHONES USED

Installation Of two-way radio tele-

has disclosed many novel uses for this
latest form of communication, accord

Pilots are In communication with
ground stations for out of every Is
minutes, exchanging messages dealing
with weather conditions and nayiga-

messages compose 80 per cent Of the
radio traffic.
Five per cent of the messages consist
of operating orders to the pilots and 4
per cent deal with traffic movements.
The remaining per cent consists Of
personal messages of passengers.

SOAP BUBBLES HELP

Physicists Method.

termine the amount of twisting a wing
beam Of an airplane viii undergo be-
fore crumpling.
A German physicist discovered that
a slightly inflated, soap bubble over q
cross section of the beam might be
made direct measure of the beams
twist resistance.
Engineers spent months developing a
bubble material that would not break
easily. Instead of breaking expensive
model beams by applying twist pressure,
they used aluminium plates, the same
shape and size and with the same holes
as a cross section of the wing beam to
be tested
They swept the bubble Aim over the
holes, inflated them slightly, then meas
ured the volume of each bubble down
to ne-thousandth of an inch. Resist
ance of each shape of wing beam has
been determined to within per cent.

production.
A ''featherweight" of $50 pounds, it is
powered with a two-cylinder motor
weighing as pounds which burns ordi-
nary motor car gasoline.
Fuel and fabrication oil are mixed
and carried in single tank built into
the cowiing ahead of the pilot.
The plane has a speed of so miles an
hour, carrying one person with the two
cylinder motor and pilot and passen-
ger with a three-cylinder engine.
It Is called the American Eaglet and
was designed by D. H. Weber. chief
engineer of the. American Eagle Co.,
"for backyard aviators."
Scaled down from full size airplane,
the tiny ship has wing span of "a
feet inches, length of 81 u feet, and
a height of 78 inches.
Its landing gear has two air wheels,
IL inches in diameter. The landing
speed Is Is miles an hour, and the plane

43,9)2 PILOTS GET
TEST DURING YEAR
Physical Examinations Top
Total for Four Previous
Years Combined.

# the number of physical examina-
lions of airplane pilots made under the
air commerce regulations is any critic
rion, aviation in the United States Is in
an exceedingly active period Of ex-
pansion.
Authorized medical examiners of the
aeronautics branch Of the Department
of Commerce conducted more physical
examinations for pilot licenses during
| the fiscal year 1880, just closed, than in
all other years combined since the or
ganization of the branch In 1926, Clar-
| ence M. Young Assistant Secretary of
Commerce for Aeronautics, announced
last night.
In the fiscal year which closed June
80 these examiners gave 43,902 physical
examinations. The total of all years
since 1926 is 81,349 The number Of
examinations made last year was 81 per
cent greater than in the 1929 fiscal
year, Mr.. Young said, only 20, 478 hav-
ing been given in that year.
A total of 22,606 students received
their first physical examinations for
pilot licenses during the fiscal year just
ended.
Examinations made by physicians of
the aeronautics branch" 1t was ex-
planned by Dr. L. H. Bauer, chief Of the
medical section of the branch, ARE di-
vided into three types-those for trans
port and limited commercial pilots,
those for industrial pilots and those for
private pilots Students may take either
the private or transport type as they
elect
For the purpose Of compiling statis-
tics DR.. Bauer said, the examinations
are divided into groups, as follows:
Original examinations of student pilots,
re- denominations of students and pilots
for higher grades or for renewal OF same
grades of licenses, and original exami-
nations Of pilots who have flown before
but were unlicensed.
1885 Are Re-examined.
In addition to the total of 1905 stu
dents examined, there were 1885 pilots
who underwent denomination. Under
this classification also came students
whose examinations had expired before
the completion of the course, as well as
the examination Of licensed pilots for
renewal Of licenses. Original physical
examinations were given to 2,435 indi-
viduals who had been flying as un-
licensed pilots.
"Of the total of 4S,902 examinations
made in the fiscal year $780," DR.. Bauer
explained, "25, 041 were OF individuals
taking their first examinations for pilots
licenses, including both students and
trained pilots. OF 22.606 original phys
ical organizations of students, l,435 were
disqualified.
"The number Of pilots and students
re-examined for the same grade OF
license which they held prior to the
time of examination totaled IL, 402. Out
of this number, 100 were disqualified.
OF the total of 6,193 denominations
for higher grade Of license, 10 were
DISQUALIFIED"
