Engine Limitations

T5 limits :

≤ 925°C            = no time limits

925°C - 980°C   = 10 seconds

980°C - 1090°C = 2 seconds

> 850°C            = should be reported and investigated for cause

T5 limit : 660°C, if the T₅ temperature approaches the 660°C idle limit, either increase N_G or reduce engine loads (for example, turn off the generator) to stay below the idle temperature limit

Oil pressures limit : On the ground , 40-80 PSI are acceptable

Oil pressures limit : In flight, 80-100 PSI at NG >72% if the oil temperature is >60°C




Oil pressures limit : <80 PSI, reduce power setting and complete the flight

Oil pressures limit : <40 PSI is unsafe, minimum power required or shutdown the affected engine
