Precautionary Descent
1.
Power ................................................................ IDLE
2.
Carburettor Heat ................................................ ON
3.
Airspeed............................................................75 KIAS
4.
Flaps..................................................................UP
5.
Bank Angle........................................................30
o
NOTE
This descent gives moderate vertical speeds. It allows good airspeed control & is suited to a
descent in a confined area (such as a hole in a cloud layer).
Alternator Failure
1.
Non-essential electrical equipment....................OFF
2.
Land.......................................................................AT NEAREST AIRPORT
NOTE
The Jabiru Engine does not require external power to run: the engine will not stop if the aircraft
battery runs flat.
Overvoltage
1.
Electrical equipment..........................................ALL ON
– MONITOR VOLTAGE
2.
RPM..................................................................REDUCE
– MONITOR VOLTAGE
3.
Land..................................................................AS SOON AS PRACTICAL
If the voltage cannot be controlled below 15.5V it is necessary to turn off items such as avionics to
prevent damage to them. Items with a high current draw, like landing lights, should be left on.
Inadvertent Spin
Intentional spins are prohibited in this aircraft. Should an inadvertent spin occur, the following
recovery procedure should be used:
1. Retard the throttle to idle
2. Centralise ailerons
3. Apply and hold full rudder opposite to the direction of rotation
4. Move stick progressively forward far enough to break stall
5.
Hold these control inputs until rotation stops
6.
As rotation stops, centralise rudder and make a positive, smooth recovery from
the resulting dive
WARNING
If the spin is encountered with flaps extended, DO NOT retract flaps until rotation ceases.
Premature flap retraction will delay recovery.
Inadvertent Icing Encounter
1.
Carburettor heat................................................ON
2.
Altitude..............................................................REDUCE IF SAFE
3.
Aircraft position / heading.................................TURN BACK
4.
Aircraft Performance.........................................MONITOR
