(If operational considerations permit)

LANDING WITHOUT ELEVATOR CONTROL

Manipulating the electric pitch trim and throttle provides attitude control

should primary elevator control be lost. Make small adjustments to trim and

throttle to adjust pitch attitude and airspeed for best glide angle for landing.

Choose the longest available runway. The final power reduction after the

landing flare will cause a nose-down pitch and a possible nose wheel first

touchdown. Make a gradual power reduction while simultaneously selecting

nose-up elevator trim.

NOTE

To relieve control stick forces, if trim has runaway nose down, land with

flaps up (0°) ; if trim has runaway nose up, land with flaps (30°).

TAKEOFF

Power check: check the full-throttle engine operation early in the takeoff run.

The engine should run smoothly and all engine instruments should

read in the green. Abort takeoff at any sign of rough engine operation, slug-

gish acceleration, or abnormal annunciation.

Flap setting: the only approved flap setting for takeoff is 10°. Takeoff data is

only presented for flaps 10°.

Soft or rough field takeoffs are performed by lifting the airplane off the

ground as soon as practical. For takeoff on gravel or other rough surface

apply throttle slowly to allow for debris to be blown behind the propeller

rather than pulled up into it.
