Landing - P&M Aviation QUIK GT450 Operating Instructions Manual

Hand Throttle
The engine RPM can be set with the cruise control lever and then the pressure on the foot pedal may be
removed until an increase in RPM is required. Thereafter, the RPM will always return to the cruise setting
when foot pressure is removed. To obtain the full RPM range on the foot pedal, the hand throttle lever must
be in the fully-off position.
Stall characteristics
Fully loaded, the stall occurs at approximately 33 mph Min. AUW, 37 mph Max. AUW, and is clean and easily
handled. As the speed is reduced, aft bar pressure increases, noticeably so immediately prior to the stall.
You will also notice a slight nodding tendency and a stiffening of roll response. As the wing stalls, the nose
pitches down and corrective action is to bring the bar back slightly to prevent the aircraft re-entering the stall
state. Pulling the bar violently in to the chest and holding it there will result in an unnecessary rapid nose-
down rotation and consequent steep nose-down attitude. The quickest stall recovery will result if the bar is
allowed to come back no further than the trim position, then as soon as the trike nose drops below the
horizon, power should be applied to check the nose down rotation, and then the pitch adjusted to resume
normal flight.
At the stall, a light wing drop may be found but is easily corrected. If necessary, hold the bar firmly to counter
any tendency for the nose to pitch up excessively during the recovery. The Quik and Quik GT450 wings are
remarkably stable, and even if stalled in a turn will not spin, but pitch down, increase air speed and roll out
into a shallow turn or straight flight. On brand new wings, which have the least wash-out, if any wing drop
tendency is found, rotate both tips up 2 divisions. See tuning section.
Stall recovery is fastest with the trimmer set slow, as the trimmer pitching moment applied to the wing will
quickly pitch it out of the dive. It is recommended that stalling exercises are done with the trimmer in the
middle position (approximately 65 mph).

WARNING
!
Applying or removing power suddenly when
near the ground can be dangerous.
WARNING
!
Do not use the hand throttle for engine control
on the ground or on take-off or landing.
WARNING
!
Whip stalls and accelerated stalls producing
steep nose-up attitudes at low airspeeds are
very dangerous and absolutely forbidden.
These manoeuvres can lead to loss of control
and/or in flight structural failure that could
result in injury or death.
