4.5.7.2 Extension and starting the engine in flight
1. With the engine extended but not running the rate of sink at 90 km/h (49
kts) increases to 1.7 m/sec. (340 ft/min.).
Therefore restarting the engine should only be done over landable terrain
and not below 400 m (1320 ft) above ground. But it is better to restart
the engine at 200 m (660 ft) over a landable field rather than at 400 m
(1320 ft) over a forest or unlandable scrub.
Should a flight be conducted over a wide expanse of unlandable terrain,
the engine should then be restarted at 1000 m (3300 ft) above ground
level so that if the engine does not start, all the emergency starting
procedures can be followed unhurriedly including retraction of the
engine if necessary.
2. In a normal restarting situation the loss of altitude from starting the
extension procedure until the engine is running is only about 20 m (70
ft).
3. Extension: Fly at 85-95 km/h (46-51 kts).
Check if the fuel cock is open.
Throttle on idle, switch on the ignition. The engine will extend by itself.
You may press the starter button before the engine is extended
completely. The starter motor will start the engine as soon as the
powerplant is extended.
When the engine fires, release the starter button and move the throttle
slowly to full throttle.
Warning: If after starting the engine the failure message "Starter Run" will be
displayed, the starter motor didn't disengage and is producing electric power,
stop the engine immediately to prevent damage of the control unit.
