6. ULTRALIGHT FLYING
6.1 Starting the engine
All controls should be checked with the ignition OFF. Passengers should have seat belts secure and be
briefed for the flight.
CAUTION
REMEMBER TO CLEAR PROP!
The engine should be started with the pilot in the front seat.
The following procedure should be used:
- Park Brake is locked in the on position
- Hand and foot throttle off
- Turn the key switch on.
- Switch both ignitions ON.
- Apply full choke unless the engine is hot.
- Check visually that the propeller area is clear and call “Clear Prop” out loud.
- Depress start button. If the engine refuses to start switch off the ignition before investigation.
- When the engine starts, increase the engine RPM to a little above idle and release the chokes.
- Oil pressure should indicate within 10 seconds.
- Warm up the engine. Minimum Temperature should be reached before take off. Operate for 2 min at 2000 rpm
continue at 2500 rpm until minimum temperature of 50 deg C is reached
.
Keep an ultralight log and enter any unusual engine behavior. Do not fly unless you have corrected a
given problem and recorded the correction in the log.
6.2 Taxiing
Taxiing in normal conditions is fairly easy.
With the engine idling the brake lever should be depressed which will disengage the park brake. The control
frame should be positioned so that it is in the approximate position for normal trim speed. The pilot’s feet actuate
steering on the ground. Left turn occurs when the right footrest is pushed forward.
Right turn occurs when the left footrest is pushed forward.
NOTE
Control sense for turning is opposite to that of a conventional three axis ultralight.
When taxiing in strong wind conditions the following procedures apply:
· Head Wind conditions requires the nose of the wing to be lowered just below the trim position.
· Down Wind conditions requires the nose of the wing to be raised just above the trim position.
· Cross wind conditions requires the upwind tip to be lowered.
6.3 Before take off
Before flight a full-throttle check is to be carried out. During this operation the pilot must be seated in the
cockpit and prepared to switch off the ignition at very short notice if an emergency should arise.
The two ignition circuits should be tested with the engine running at 4000 rpm. Ignition one should be
switched off and the RPM drop should not exceed 300 rpm. Both ignitions should be in the on position
and ignition two should be turned off and the RPM drop should not exceed 300 rpm. Ensure both
switches are in the on position after ignition circuit testing.
WARNING
NEVER LEAVE YOUR ULTRALIGHT UNATTENDED WHILE THE ENGINE IS RUNNING.
CAUTION
BEWARE OF LOOSE STONES IN THE RUN UP AREA. LOOSE STONES CAN BE SUCKED UP BY
THE PROPELLER AND CAUSE SEVERE PROPELLER DAMAGE IN A VERY SHORT TIME. RUN
UPS ARE BEST CONDUCTED ON A CLEAR SEALED SURFACE OR ON GRASS, NEVER ON
GRAVEL
