LANDING WITH A FLAT NOSE TIRE
CAUTION
Do not attempt to taxi airplane with flat main or nose gear tire.
1. Approach Speed.................................................................... 65 KIAS
2. Flaps................................................NO MORE THAN 10 DEGREES
3. Touchdown ...............................................................ON MAIN GEAR
(Hold nose wheel off the ground as long as possible)
4. Elevator.................................................MAINTAIN FULL AFT STICK
(After nose wheel touches down)
5. Brakes.....................................................USE MINIMUM REQUIRED
6. Ignition Switch...............................................................................OFF
(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.
1. Throttle................................................................................. REDUCE
2. Trim............................................................ NOSE UP, SLOW TO VFE
3. Flaps..................................................................................FLAPS UP
4. Approach Speed.....70 KIAS, USE TRIM AND POWER TO ADJUST
5. Throttle......................................AS REQUIRED FOR GLIDE ANGLE
