TAXIING

a. Caution must be used in taxiing because the rudder is

ineffective and steering by engine thrust is difficult as

thrust builds up too slowly. Brakes are the only means of

control, and taxiing should be done with jet units running at

4000 to 6000 rpm. The tail of the ship must not be turned

toward inflammable objects.

TAKE-OFF

(1) Hold aircraft with main wheel brakes and open throttles

very slowly to 7000 rpm.

(2) Release brakes and open throttles fully. Make direction

al corrections with brakes only. After flying speed (approx-

imately 112 to 125mph (180 to 202 km/hr)) has been attained,

pull gently back on stick to raise nose wheel and make the

take-off.

(3) Apply brakes and retract gear when airborne. Landing

gear signal light should indicate wheels in "up" position.

(4) Retract flaps - airplane will not drop through.

Note: By opening throttles too fast up to 7000 rpm there is danger

of causing cavitation in one of the compressor stages, that is,

by running up too quickly the compressor is overloaded and the

smooth air flow breaks up just as it does on a stalled wing. If

take-off is continued, insufficient air flows through but the

same amount of fuel is injected, resulting in insufficient

power.

ENGINE FAILURE DURING TAKE-OFF

a. If the speed of the aircraft is low, close the throttles and

apply the brakes. (Main wheel brakes are foot-operated, nose

wheel brake is hand-operated).

b. If already airborne, retract the landing gear as soon as

possible, keep the nose down, and use the rudder as necessary

to maintain direction until the rudder trim can be adjusted.

Continue around the pattern, turning in the direction of the

good engine. Minimum single engine speed is 260 km/hr (160

mph).

CLIMB

a. The best climbing speeds are given in the take-off and climb

chart in Appendix 1.
