7) System Description

This chapter of the Operators Manual (OM) contains
information about the general engine specification as well as a
description of cooling system, fuel system, lubrication system,
electric system and the propeller gearbox.
The system description refers only to the engine and not to a
specific application in a particular aircraft. The aircraft
manufacturer's Operators Manual (OM) is therefore definitive in
terms of the operation of the engine, as it contains all the
aircraft specific instructions.
The design shown in this chapter does not represent a
specified execution but should support the understanding of the
system.
