3. Emergency procedures
3.1. Introduction
Section 3 provides checklist and amplified procedures for coping with
emergencies that may occur relevant to the Jet System.
3.2. Engine failure in flight
If an engine failure occurs during flight, the engine can be restarted or
retracted. Retraction will only be initiated after the cooling down cycle
has been completed.
Procedure to restart engine in flight
1. Restore normal flight attitude and stabilize airspeed at a safe
flying speed (100km/h (54 kts) to 120km/h (65 kts)).
2. Ensure that the fuel shut off valve is open and that sufficient
fuel is available.
3. Cycle the Jet Control toggle switch from “RUN” to “EXT” and
back to “RUN”.
4. Observe the start-up screen for sufficient battery voltage, and
normal EGT and RPM increase or other error messages.
5. Once the engine runs normally, the throttle may be adjusted
to the required setting.
NOTE:
If a restart is not possible, the engine may be retracted
and the soaring flight continued, or a landing may be
performed with the engine extended.
