WARNING
Non-compliance can result in serious injuries or
death!
The current consumption of the remaining consumers
is to be limited so as to ensure that power is supplied
to the internal consumers (e.g. fuel pumps, ECU etc.)
at all times.
The battery and all loads in the aircraft must be di-
mensioned so, that even if one of the generators fails,
a safe flight is ensured.
See the performance diagrams of the internal and ex-
ternal alternators as a function of engine speed.

Fuel pump (additional pump) min. 10 A
