b. Speeds of 950 km/hr (590 mph) are reported to have been attained

in a shallow dive 20° to 30° from the horizontal. No vertical

dives were made. At speeds of 950 to 1000 km/hr (590 to 620 mph)

the air flow around the aircraft reaches the speed of shound, and

it is reported that the control surfaces no longer effect the

direction of flight. The results vary with different airplanes;

some wing over and dive while others dive gradually. It is also

reported that once the speed of sound is exceeded, this condition

disappears and normal control is restored.

SPEED AND RANGE

Flight Condition

Max speed, 20° to 30° dive

Take-off with full fuel load

(no bombs)

Cruising speed

Max speed, level flight

Landing approach

Stalling speed with full fuel load,

landing gear and flaps down

True Air Speed (Indicated)

950 km/hr (590 mph)

180 to 202 km/hr (112 to 127mph)

750 km/hr (465 mph)

830 km/hr (515 mph)

250 km/hr (155 mph)

202 km/hr (125 mph)

The flight duration of the aircraft varies from 45 to 90

min. Time of flight at low altitudes (below 10,000 to 12,000

ft.) is 45 to 50 min. At altitudes above 12,000 ft the time of

flight is 60 to 90 min. The increased efficiency with altitude

is a result of decreased air pressure.

TO TURN OFF JET UNIT DURING FLIGHT

a. Training or test flights:

(1) Close throttle to idling position.

(2) Turn off fuel pump, allowing rpm to decrease.

(3) Fuel selector valve off.

(4) Throttle closed.

(5) Press ignition button throttle for five seconds.

TO START DURING FLIGHT

a. Do not start above 4 km (13,100 ft) because of fire hazard.
