INSTALLATION MANUAL
Flight test example:
Calculated values (maximum values found for coolant temperature and cylinder
head temperature. Refer to the current specification of the FAA and/or EASA):
Coolant temperature.....................102 °C (216 °F)
Cylinder head temperature...........110 °C (230 °F)
The cylinder head temperature is 8 °C higher than the coolant temperature.
Thus:
Coolant temperature limit...............................................120 °C (248 °F)
Difference cylinder head and coolant temperature..........+
8 °C ( 46 °F)
= 128 °C (262 °F)
The highest cylinder head temperature permitted is 128 °C (262 °F), so that the max.
coolant temperature is kept.
With this special application, safe operation of the engine that prevents boiling of the
coolant is possible up to a cylinder head temperature of 128 °C (262 °F).
■ CAUTION:
This cylinder head temperature with the limit found for this type
must be displayed constantly in the cockpit.
The indicating instrument and the manuals must be changed to
cylinder head temperature max. 128 °C (262 °F).
The design of the radiator installation must be changed (example:
cowl modifications), such that the operating temperature will not
exceed the specified limits.
