TAKE-OFF & LANDING CONSIDERATIONS
See TAKE-OFF & LANDING CONSIDERATIONS, Section 8-1.
TRAFFIC PATTERN
Enter the traffic pattern at the proper traffic pattern altitude. Maintain traffic pattern altitude and adjust power
(between 3800 to 4000 RPM) so as to arrive on downwind opposite the target touch-down point at 80 KIAS and
target altitude. Smoothly reduce power to idle, maintaining target altitude until airspeed decays to 65 KIAS. Lower
flaps to ½ deflection and trim the stabilator. Maintain the target airspeed by trimming and allowing altitude to decay.
If able, choose a point for base turn that will allow arriving at the target touch-down point while maintaining engine
power at idle. Vary descent rate by lowering flaps to full deflection. Allow airspeed to decay to 60 KIAS and trim
control pressure off.
Choose point for the turn to the final approach leg so as to make ground contact at the target touch-down point at
minimum airspeed while maintaining engine power at idle.
Descent rate may be increased by slipping the aircraft at idle while maintaining airspeed.
Descent rate may be decreased by addition of engine power.
NORMAL LANDING
See POH Checklist
Once established on final approach, maintain 55 KIAS until the main wheels are approximately 5 feet off the
runway. Fully close the throttle if any power had been added. Smoothly raise the nose to a landing attitude without
gaining altitude or "ballooning." If the aircraft gains altitude, the transition to landing attitude is being made too
quickly.
Once the aircraft is in the landing attitude, continue to smoothly move the stick aft while allowing the aircraft to
slowly descend until the main wheels contact the runway.
With main wheels on the runway, maintain nose-high attitude (nose wheel held slightly off runway surface) by
continuing to hold back pressure on the control stick while nose wheel slowly lowers to the runway due to reduced
airspeed. Hold control stick full aft as speed decays and stabilator effectiveness diminishes.
Apply brakes if/as required to stop before the end of the runway or to make the next runway turn-off. For maximum
brake effectiveness after all three wheels are on the ground, retract the flaps, hold stick full aft and apply maximum
possible brake pressure without sliding the tires.
SOFT-FIELD LANDING
The best technique for use on soft or rough fields is to fly the landing approach at minimum speed carrying some
power into the landing flare and using an exaggerated nose-high landing attitude so as to touch down with
minimum airspeed.
To avoid unnecessary nose gear loads, it is especially important that the nose wheel is held off the ground and
lowered gently to the runway after speed has diminished.
