two and one fourth hours' basic fuel capacity. The three-fourths hour fuel supply, is is understood, will be in field removable tanks.

If possible, gas tanks should be placed on the main wing on multi-motored machines.

MOTOR MOUNTS.

All motor mountings should be of the easily demountable type with a minimum number of connections so as to facilitate the changing of motors in the field.

LANDING GEARS.

Oleo landing gear development should be pushed vigorously and the purchase of several of these Oleo gears for adaptation to some of our existing types, will overcome inertia at least in the development of this type. Our designers and engineers in the field would see the practicable adaptation and feasibility of such types as exist abroad.

On large bombardment multi-motored types, the main chassis wheel should be placed as near the center of gravity as possible to facilitate handling on the ground by ground crew; and auxiliary wheels to prevent nosing over should be installed immediately forward but not carrying the load of the airplane while taxi-ing.
