INSTALLATION MANUAL
The oil cooler has to be installed with connections upwards i.e. in
positive direction on z-axis. This will prevent an unintentional draining
of the oil cooler at longer engine stop.
This will prevent an unintentional draining of the oil cooler at longer
engine stop.
operating temperatures are maintained and the max. values are
neither exceeded nor fall below.
This state has to be warranted for "hot day conditions" too!
If need be, take appropriate measures like changing size of cooler,
partial covering of cooler etc.
EASA has to be conducted by the aircraft manufacturer.
The oil cooler has to be designed to dissipate approx. 10 kW
(8,5 BTU/s) heat energy at take-off power.
From years of experience we recommend an oil cooler size of at least
160 cm 2 (25 in 2 ), provided that air flow is adequate.
The oil cooler must not restrict oil flow. Test system as per sec. 13.3.
