Prior to take-off
•
Make sure the fuel valve is open.
•
Fasten and check seat belts engagement. WARNING: Safety belts should be placed at hip
level and tightened correctly. The strap loops under the seats are positioned to ensure
correct safety belt positioning. Never remove safety belts from the strap loops under the
seats: Safety belts fastened at abdominal level may cause internal injury in the event of
violent shock.
•
When aircraft is equipped with shoulder's strap, pull the buckle to release the winding
system and fix it on the locating lug provided for this purpose, on the belt's side.
•
Check ignition switch by rapidly switching OFF and then ON with engine operating.
•
Check that the switch selector is on the central position 1+2.
•
Check that the control bar moves freely in roll and pitch axis.
•
Release the parking brake by a short pression of the brake pedal.

Take-off
Use progressively full throttle when carrying a passenger. Throttle back slightly after having
climbed 300 ft (100 m) to reduce engine wear. When flying solo, 3/4 throttle will suffice for
take-off and climbing. Only use full power under critical conditions (short take-off runs,
obstacles, high-altitude flight). In that case
never reduce or cut the engine
below the 300 ft
(100 m) altitude to avoid dynamic stalling. For safety reasons, use the throttle lever rather than
the foot pedal at take-off on rough terrain.
Never take-off with less than 2.5 gallons petrol
(10 l).
The recommended speed for initial climb is indicated in the wing’s manual.
−
Cruising
Keep the aircraft level with the throttle between 1/4 and full depending on given airspeed.
Avoid repeated and sudden power climbs and idle dives to prevent sudden engine temperature
changes, which could damage the engine by thermal shock. Fuel tank contents are easy to
check as the tank is translucent and one can easily see it from both pilot and passenger seats.
Landing shall be considered before tank contents has reduced to 1.5 gallons (5 liters). This
allows approximately 30 minutes reserve of flight at low cruising speed. (This level
corresponds to the upper part of the metallic tank bracket).
−
Landing
The landing approach is best executed using the foot throttle pedal and both hands on the
control bar. At maximum load, keep the throttle at 1/4 of full power when on final to facilitate
flare-out. Throttle back when the wheels touch the ground.
−
Parking
•
Place the aircraft across the wind and place the extremity of the half-wing in the wind on
the ground.
•
Stop the engine with the ignition switch.
•
Block the parking brake with the rack on the right side of the throttle.
•
Block the control bar on the front strut of the trike using a Velcro.
•
Leave the trike, pilot first, and always on the left side.
