RPM. Check maximum power lever position as follows:
The only requirement of the maximum power lever position
check is to verify that it is possible to obtain maximum
allowable gas generator RPM (N1) with the power levers in the
full forward position. If during the test the TGT temperature
limit or N1 limit is obtained prior to reaching maximum N1, the
check is completed.
Altitude - 25,000 feet pressure altitude.
Propeller levers - Set 2000 RPM.
Ice vanes - Retracted.
Bleed air valve switches - OPEN.
Airspeed - As required.
Power levers - Full forward (do not exceed TGT and/or N1 limits). Maximum N1 is 101.5%. Maximum
TGT is 750°C.
*D. SPEED CHECK AT MAXIMUM CR UISE POWER.
A new or rebuilt engine operated at the torque value presented
in the cruise power charts will show a TGT margin below the
maximum cruise limit for the torque value presented in the
charts. With ice vanes retracted, cruise torque settings shown
on the cruise power charts should be obtained without
exceeding TGT limits.
Speed-power runs shall be made in smooth air to determine consistency with performance figures. Torque
settings, fuel flow, and airspeed to be achieved will be
