What is the aircraft wingspan?

9.11 m

What is the prop diameter?

2.39 m

How is directional control of the aircraft on the ground achieved?

Through differential braking or nose wheel steering or both.

Can the aircraft be turned on a locked main wheel? If so, how? Is it recommended.

Yes. Through moderate braking and engine power. Not recommended due to excessive engine wear.

Which direction is turning radius larger and why is that the case?

Larger to the right due to propeller slipstream and torque effects.

500 NM at 10,000 ft 620 NM at 20,000 ft 660 NM at 25000 ft

When should the seat pin only be removed?

After the aircrew is correctly strapped in and the canopy is closed and latched.

How is the ejection seat made live?

By removing the pin, which is then inserted into the stowage in the left hand side of the glare shield.

What must the flight crew observed before closing the canopy with the CFS pin removed?

1. Visually verify that the CFS striker plate is unobstructed, and the MDC trip lever has no yellow area visible. 2 Wear gloves, helmet and mask with at least one visor lowered. 3. There are no personnel within CFS blast area
