ENGINE FAILURE IN FLIGHT
CAUTION
DO NOT SHUT DOWN AN ENGINE DURING TAKE-OFF OR LANDING
BECAUSE OF SUSPECTED ENGINE FAILURE UNLESS AN ENGINE
MALFUNCTION IS DEFINITELY DETERMINED.
WARNING
DO NOT ATTEMPT TO RE-START AN ENGINE, IF THE ENGINE FAILURE
WAS THE RESULT OF A TECHNICAL PROBLEM.
NOTE
For a power off landing establish the best glide speed, which should be
not less than 75 knots IAS.
AIR START
An engine flame-out will be noticed by an indicated drop in ITT, torque
pressure, Ng and Np.
The recommended air start technique is to initiate the Immediate
Relight procedure immediately after the flame-out occurs, always
assuming the flame-out was not the result of an engine malfunction
and the aircraft’s altitude does not allow the crew to perform a Normal
Relight Procedure.
If the Ng is less than 46%, a Normal Relight should be initiated.
The relight envelope for successful air starts covers all operational
altitudes and airspeeds. When restating above 20,000 ft, starting
temperatures may tend to be high.
