Ecu/Fuel Pumps Test Sequence; Under 7500 Ft - Diamond DA 62 Flight Manual

DA 62 AFM

ECU/fuel pumps test sequence

The following test sequence can be executed for both engines
simultaneously, or in sequence.
The engine/gearbox oil temperatures have to be in the green
range before starting the test sequence. Efficient engine
warm up may require higher power settings (max. 50% engine
power).
During the test sequence the engines will produce thrust
therefore the parking brake must be set.
A. Under 7500 ft
If the L/R ECU A/B FAIL indicators do not illuminate during
the test sequence there is a malfunction in the engine control
system. Terminate flight preparation.
The whole test procedure must be completed without any
error (L/R ECU A/B FAIL extinguished after test completion).
In case the test procedure aborts with an error indication (one
or both ECU A/B FAIL indicators remain ON) terminate flight
preparation, even if the engine seems to run smoothly after
the test procedure.
