Always start the engine on a flat and clean surface, without stones or sand. During all
phases in which the engine is kept running near the ground (such as heating, take off,
landing) it is necessary to maintain a safe distance from the engine. A good safety
distance is 100 meters in every direction.
The following engine speed limits must be respected to avoid engine failures, to keep the
warranty valid and to have a correct maintenance scheduling according to the Vittorazi
program:
•
Do not keep the engine at full revs for more than 60 seconds.
•
Do not keep revs higher than 6.500 RPM during long cruising flights or long climbs.
The average power delivered by the engine during a flight should remain below the
indicated threshold. Contact the aircraft manufacturer for further clarification.
For the proper engine operation, the coolant temperature measured by the head sensor
must be within the limits indicated below. In case of a temperature outside the indicated
thresholds (Min; Max), contact the aircraft manufacturer.
•
Max
90 °C.
•
Min
65 °C.
The temperature limit of EGT is 650° Celsius. Do not persist above this temperature
threshold, engine overheating and irreversible damage could occur.
