Airplane Description DA 62 AFM
In accordance with the received signals and a comparison with the programmed
characteristic diagrams, the necessary inputs are calculated and transmitted by the
following signal lines to the engine:
- Signal for propeller governor pressure valve
- Signal for the rail-pressure regulation valve
- Signal for each of the 4 injection nozzles
- Activation of the glow plugs
- Signal for the waste gate valve
The following alerts are displayed on PFD of the G1000:
- Glow sparks active
- Status ECU A
- Status ECU B
- Low fuel pressure
The electronic ECU consists of two ECUs per engine. A VOTER switch is integrated in
the electronic ECU and proposes (if set to AUTO) an ECU to control the engine regarding
the ECU operating hours or - in case of a failure - the ECU with better engine control
capability. If the VOTER switch is set to A or B, the related EECU is forced to control the
corresponding engine with ECU A respectively ECU B.
A fault detected by the ECUs is indicated by a caution message on the PFD
(L/R ECU A/B FAIL). Two types of faults are known:
- Faults which lead to a latched caution indication
- Faults which lead to a non-latched indication
In case of a latched caution, unscheduled maintenance is necessary and Austro Engine
GmbH has to be informed.
