ONLY:
"Never exceed 60 in Hg. in a climb above 25,000 feet.
GENERAL FLYING CHARACTERISTICS
a. Due to the counter-rotating propellers, there is no noticeable torque effect in any two engine flying
with this airplane. Rudder and aileron trim tab settings do not require adjustment as a result of
changes in airspeed and power.
b. TO INCREASE POWER IN FLIGHT
1. Move throttles to the new manifold pressure.
2. Move propeller controls to the new RPM.
3. Move the throttles to the new manifold pressure.
c. TO DECREASE POWER IN FLIGHT
1. Move the throttles to the new manifold pressure.
2. Move prop controls to the new RPM.
3. Re-adjust the throttles
4. Move mixture controls to AUTO LEAN is permissible.
d. The turbo superchargers are controlled by the same levers which operate the throttles. Rated
supercharger speed is 24000 rpm allowable for five minutes and overspeed is 26400 rpm. The
warning lights start to flicker at 25,600 rpm and burn continuously at 26,400 rpm.
e. On P-38J aircraft the intercooler flap should be open for take-off and climbs and nearly closed at
all other times. Carburetor air temperature should not be allowed to exceed 45 degrees cent.
f. The airplane is stable at all normal speeds. The airplane becomes slightly nose heavy when the
flaps and landing gear are extended. Release of drop tanks causes no noticeable change. Two-engine
