Engine Management – Ground Running
The 3300A engine fitted to the J230-D is cooled by air flowing over the engine and oil cooler.
During ground running care must be taken to ensure that there is adequate airflow and that safe
engine temperatures are maintained. The guidelines presented below will assist in controlling
temperatures.
•
Minimise ground running times – especially in hot weather

.
•
Carry out as many checks as possible before starting the engine.
•
Always carry out engine run-up tests with the aircraft pointing into wind.
•
In hot weather, after performing run-up checks, leave the aircraft pointing into wind and
idling at 1200rpm for 30 seconds to aid cooling.
•
If the aircraft is required to wait – such as for runway clearance – temperatures must
be monitored, and if they approach ground running limits (listed in Section 3 of this
flight manual & displayed as yellow markings on engine gauges) the aircraft must be
turned into wind or shut down to prevent any further temperature increase.
•
Wind must be coming from within approximately 45° of the aircraft heading to be
effective in aiding engine cooling.
•
If there is no wind or low wind the engine must be shut down if ground-running
temperature limits are reached.
