Caution: The airflows shown in this table will provide acceptable cooling for an open power unit operating in ambient temperatures of up
to 53 °C (46 °C if a canopy fitted). If the power unit is to be enclosed totally, a cooling test should be done to check that the engine cooling
is acceptable. If there is insufficient cooling, contact Perkins Technical Service Department.
