equipped with an external alternator. This is a
state-of-the-art, electromechanical three-phase
generator (compact generator) with small outer
dimensions. It has the task of supplying the elec-
tric consumers with energy and charging the
starter battery with the least possible fuel con-
sumption and low noise levels during operation
of the aircraft.
DRIVE
Drive is provided by the engine by means of a V-
belt.
