the N. A. A. this country's organization
could have kept its own official records
of parachute jumps or other events
which it deemed Of importance to
aeronautics or of sufficient interest to
justify making them of permanent
record.
1t is the policy of the National Aero
nautic Association to sponsor only such
competitions as will further the de-
velopment OF aeronautics, 1t was ex.
planned in announcing the decision oil
the Contest Committee.
Not only has the Contest Committee
as a result of its latest meeting a few
days ago, branded parachute records
as unworthy of recognition; it also has
voiced the opinion that solo endurance
flights are dangerous and that 1t Is
unWise to encourage them.
Such flights" it was stated. "are be-
lieved to be largely test Of the pilots
ability TO keep awake, whereas endur-
ance flights with a crew, with or with
out refueling, as now recognized, are
tests Of the airplane and engine.
Radio Chain Advanced.
Installation OF radio communication
facilities on all American airnlail routes
now is 80 per cent complete, after two
wears of work, and two-way radio-tele-
phone service between ground ano
planes has been provided on virtually
all the major air routes.
One Of the final links In the chain oi
aviation radio stations was forged by
virtue Of a shift in wave-length allo-
cations ordered by the Federal Radio
Commission effective on February l, &C
cording TO Paul Goldsborough, head OF
the public utility subsidiary Of the or
ganized airmail operators.
In the switching of assignments
which affects all radio wave lengths
other than broadcasting. new bands OF
cial aviation. Aeronautical radio sta
tions have been established in 90 cities
by the industry, apart from those sci
up by the Department Of Commerce
AeronauticS Branch. These stations are
the dispatching units of the various ali
transport lines and are used to main.
tain communication with planes ir
flight and between ground stations and
for the routing OF passenger and mai
planes.
The industry has set up, as a sub
sidiary OF the organized air transport
lines, its own radio outfit, known as
Aeronautical Radio, Inc. Herbert
Hoover. jr., eldest son of the President
was one Of the founders and first presi-
dent Of this organization which nov
is headed by Mr. GoldsbOrough.
The organization, in setting up its sc
stations, serves all commercial aviation
rather than individual air lines and Sc
is able to maintain a Co-ordinated
service with minimum OF stations anc
Of interference.
Service Is Explained.
The two-Way contacts between the
planes and the ground" Mr.. Colds
borough explained, all are by tele.
phone. The radiophone installation /,
as simple to operate as the ordinary
desk phone. This is necessary because
many of the aircraft carry only pilot
who has no time to manipulate tele-
graph key and the other accessories
common to the older types Of radio
communication. These new installa
tions are entirely self-contained, and
it is possible to communicate at al
times. The normal range of the air
craft set is about $50 miles but it is
not at all unusual to get contacts at
ranges we'll over 1000 miles.
Radio is serving as the eyes and ears
OF commercial aviation" Goldsborough
