Figure 2-3. Engine Operating Limits
1
1. Per the Maximum Engine Torque For Takeoff figure of Section
5.
2. For every 10°C (18°F) below -30°C (-22°F) ambient temperature,
reduce maximum allowable
Ng by 2.2%.
3. Normal oil pressure is
85
to 105 PSI at gas generator speeds
above 72% with oil temperature between 60" and 70°C (140" and
158°F). Oil pressures below
85
PSI are undesirable and should
be tolerated only for the completion of the flight, preferably at a
reduced power setting. Oil pressures below normal should be
reported as an engine discrepancy and should be corrected
before the next flight. Oil pressures below 40 PSI are unsafe and
require that either the engine be shut down or a landing be made
as soon as possible using the minimum power required to sustain
flight.
