開車前檢查

Installation on board and starting engine

When sit in the cockpit, it’s IMPERATIVE to make ALL the following controls:

- Stick back => elevator up

- Stick forward => elevator down

- Stick left => left aileron up and right aileron down

- Stick right => right aileron up and left aileron down

- Push right foot => rudder right

- Push left foot => rudder left

-Fasten the safety harness

-Check the doors are locked

Before any engine starting action, it is essential to check there is nobody around the aircraft,

especially in the propeller area.

5-2.1 : Start engine cold

- check open tank vent

- give the squeeze bulb a few pumps, or start the electric pump (optional), to fill the

carburetor bowl

- check switch is "OFF"

- pull the propeller through 10 -15 turns (20 to 25 in very cold weather)

- choke lever "ON", throttle : closed

Note: fitting the optional priming set spares you this procedure.

- turn ignition "ON", clear all spectators from front and sides of propeller

- pull starter rope or push on electric starter button

This may be done while seated. Place left foot on rudder bar and hold starter handle in both hands.

If this feels inconvenient, start from outside but make sure you have a competent

helper in the cockpit, ready to keep the aircraft from moving forward.

- as soon as engine is running, throttle to half-RPM and warm up for a few minutes,

moving choke to "OFF" gradually.

5-2.2 Start engine hot

- if the engine has been running quite recently, simply turn ignition "ON", choke "OFF", throttle closed, and start. The engine will start instantly.

- if more than 15 minutes have passed since the engine was stopped, start same as just above, but with choke "ON".

Move choke to "OFF" immediately when engine starts.

CAUTION! NEVER TAKE OFF WITH CHOKE "ON":

This would make the engine lose power very quickly and might result in engine

stoppage on take off, with foreseeable consequences!

 

起飛前檢查

Check:

- altimeter set

- check controls move freely and to the stops

- trim tab : centered

- both seat belts fastened

- parachute: control box plugged and tested (optional)

- enough fuel in tank: never take off with less than 10 liters (2,64 US gals, 2,2 Imp.)

- Clearance: approach and runway clear

- radio check if required

 

起飛程序

- Runway clear, and of sufficient length

- Run up at half RPM, check temperatures

- Check both ignition circuits at half-RPM. Drop should not exceed 300 RPM

- electric fuel pump "ON" (option)

- brake "ON" for full throttle test. (less if aircraft moves forward)

- throttle closed all the way : engine should not stop

- apply full throttle gradually

- stick slightly back to ease nosewheel up

- check you are tracking straight

- slowly rotate at about 70 km/h

- maintain 90 km/h through climb-out

- maintain full throttle to 150 m (500 ft )

- electric fuel pump "OFF" ("ON" may cause excess fuel consumption)

- to use the flaps on take off allows a reduction of minimum speed of:

5 km/h (approx 3 mph) in the first position (do not exceed 120 km/h with flaps in

the first position)

10 km/h (approx 6 mph) in the second position (do not exceed 110 km/h with flaps

in the second position)

爬升程序

- maintain air speed at 90 km/h

- check temperatures

- do not exceed specified limits

The aircraft enters turns easily and without much adverse yaw.

Control your angle of bank at all times, and at first, use little amounts of bank: 10° in final to

begin with.

Never forget that stall speed increases with bank.

You will soon come to enjoy the aircraft's excellent maneuverability.

However, always keep in mind that aerobatic flight in ultralights is PROHIBITED!
