Notes: 1. The engine operating time at take off power should not exceed
10% of the total operating time throughout the TBO, allowed time
of continuous operation is 6 minutes.
In case of necessity it is allowed to run the engine continuouslyfor
15 minutes at takeoff power provided the summed operating time
in these conditions does not exceed 1,25% of allowed operating
time throughout the TBO (included in 10%). In case of failure (shut
down) of one of the engines it is allowed to run the other engine at
take off power for 30 minutes within 0,5% per TBO.
2. The engine contingency power is used only in case of failure of one
of the engines.
The engine operating time at contingency power should not exceed
0,1% of total operating time throughout the TBO. It is allowed to
run the engine continuously at contingency power for 2,5 minutes
without any limitations within the mentioned operating time.
3. The gas generator rotor speed oscillation at steady power settings is
allowed within ±0.5%.
4. With the engine running at steady ratings oscillation of the TGT indi-
cator pointer within ±25 °C is allowed providing the maximum limit
TGT is not exceeded.
5. The difference in the gas generator rotor speeds during simultane-
ous operation of both engines should not exceed the following lim-
its:
2% at normal power and cruising power 1.
3% with the TGT regulator operating.
6. The oil pressureoscillation within ±0.25kgf/cm
2
read on the indicator
are allowed at all steady power settings provided the established
limits are not exceeded.
7. The engine oil pressure should not exceed 4.8 kgf/cm
2
at oil tem-
peratures of less than 70°C during the engine warming up at idle.
