COOLING SYSTEM
General note The shape, size and position of the radiator(s) depends mainly on the
space available in the aircraft.
When correctly installed in the aircraft, the optionally available BRP-Pow-
ertrain radiator has enough cooling capacity to keep within the standard
specified operating limits. The flow resistance of the radiator coolant is
correctly adjusted to the cooling system. The tube size must be sufficient.
The size , shape, orientation of all cooling components must not compro-
mise the engine cooling under all operation conditions.
