THE major problems that have arisen
to date In the search for the solu-
| ton of fog flying are:
/. The improvement Of airplanes and
instruments, assuring a safe flying atti-
tude in fog.
2. Maintenance of course and the 10
cation of landing fields while flying
through fog.
g. The development of instruments
TO show accurately the height OF an air.
plane above the ground. replacing the
| barometric instruments now in general
use to show the height above sea level
4. The penetration of fog by light
rays.
5. The dissipation OF fog.
6. The perfection Of communication
systems between airplanes and the
ground
Valuable contributions 10 this develop
ment have been made by the Army Air
Corps at Wright Field, by the Navy at
the Navy Aircraft Factory In Philadel-
phia and the Naval Air Station at Lake
hurst and the Bellevue Laboratory, by
/ the Department Of Commerce at the
Bureau of Standards and by the Ma
| tional Advisory Committee for Aero
nautics at its laboratory at Langley
| Field. In addition. the aeronautical
