Take Off
AirBorne trike wings have a neutral static balance allowing a safe take off that is controllable under all
suitable flying conditions.
Take off should be made on full power with only the foot activated throttle used during take off.
The take off run is the measured ground distance covered until the aircraft reaches a height of 50 feet
above the average elevation of the runway used. Refer to Section 5 for details of take off performance.
During the take off run, the wing should be held in the trim position with the wings level. Accelerate
smoothly to the take off safety speed. If the aircraft is fully loaded you will require full power.
When the aircraft reaches the take off safety speed the control bar should be pushed steadily forward
until the trike lifts and rotates quickly on the main wheels. As the aircraft leaves the ground the control bar
must be eased back to maintain take off safety
speed.
Maintain your engine in top condition and assume
it’s going to stop running at any time. Leave
yourself a way out for an unexpected engine
failure.
Never fly your aircraft at locations, airspeeds, altitudes, or under any circumstances from which a
successful engine off landing cannot be attempted.
4.8.15
Climb
Initial climb out should be made on full power for
maximum take off weight. Approximately 2/3 of
maximum take off power is considered comfortable
for a minimum weight take off. Take off distance
will be extended at reduced power.
Once climb is established, power should be
reduced to below maximum continuous power of
5500 rpm. A minimum of take off safety speed
should be used. At this speed the aircraft would
round out nicely into a glide should the engine fail.
Avoid pitching the nose of the wing up more than
45 degrees to the horizon. Very steep climbs are dangerous and can result in a stall followed by a severe
pitching of the nose forward. Professional training is required for the correct procedures of unusual
attitude recovery.
4.8.16
Cruise
When the desired flight altitude is reached the aircraft may be levelled out and throttle reduced to that
required to maintain level flight.
The hand-operated throttle on the right side of the seat frame can be used to set engine rpm. Once the
hand throttle is adjusted the pressure on the foot pedal may be removed. When the hand throttle is
actuated increased power can still be achieved with the use of the foot throttle. The rpm will always return
to the cruise setting when foot pressure is removed. If the hand throttle is set a reduction in RPM is not
achievable using the foot throttle. The hand throttle must be in the off position to achieve low RPM.
CAUTION
HIGH-ANGLE
CLIMB-OUTS
NEAR
THE
GROUND SHOULD BE AVOIDED.
WARNING
AT LOW ALL UP WEIGHTS, THE TAKE OFF
CLIMB OUT AT THE TAKE OFF SAFETY
SPEED CAN RESULT IN HORIZONTAL PITCH
INCLINATIONS
IN
EXCESS
OF
THE
PLACARDED 45 DEGREES MAXIMUM. THE
PILOT MUST BE AWARE OF THIS AND
SHOULD KEEP WITHIN THE PLACARDED
LIMITATIONS
BY
LOWERING
THE
ATTITUDE OR REDUCING ENGINE POWER.
WARNING
REDUCED POWER TAKE OFFS WILL EXTEND TAKE OFF DISTANCE. IT IS THE PILOTS
RESPONSIBILITY TO ENSURE THAT THERE IS SUFFICIENT RUNWAY AVAILIABLE TO CLEAR
ALL OBSTACLES WHEN CONDUCTING REDUCED POWER TAKE OFFS.
