WARNING
The MAIN fuel pump is no longer supplied with electricity in case alternator 2 (ALT2) has failed
and the fuel pump is separated from the remaining on-board power supply by turning ALT2
switch off. In this case the AUX fuel pump is the only fuel supply for the engine.
NOTE
The remaining Alternator 1 (ALT1) is delivering up to 42A into the on-board power supply and a
properly maintained and fully charged battery alone is able to supply all necessary systems
with electricity for at least 30 minutes.
Despite the pilot turned off the audio panel it is still possible to radio with COM1 via the headset
because the audiopanel is establishing a connection even if it is turned off (failsave design).
Intercom functionality ist not possible anymore!
WARNING
Before returning the aircraft to service, problems must be investigated and damages must be
resolved.
