7) Description of systems
Introduction This chapter of the Operator Manual contains the description of
cooling system, fuel system, lubrication system, electric system
and the propeller gearbox.
Table of content As already mentioned in the preface, the system descriptions only
apply to the engine, not to a specific application in a particular air-
craft. The aircraft manufacturers Operators Manual is therefore
definitive in terms of the operation of the engine, as it contains all
the aircraft specific instructions.
