SPEED CHECK AT MAXIMUM CRUISE
A new or rebuilt engine operated at the
torque value presented in the engine accep-
tance table will show a TGT margin below
the maximum cruise limit for the torque val-
ue presented in the table. With ice vanes re-
tracted, cruise torque settings shown on the
engine acceptance table should be obtained
without exceeding TGT limits.
Speed-power runs shall be made in smooth air to de-
termine consistency with performance figures. Torque
settings, fuel flow, and airspeed to be achieved will be
determined by reference to maximum cruise speed/
engine acceptance chart (figure 4).
1. Record the following:
*a. Engine serial number
*b. Engine hours since new
*c. Engine hours since overhaul
2. Airspeed - Refer to table.
3. Altitude - Refer to table.
4. FAT - Refer to table.
5. Power setting - Refer to table.
6. Propeller RPM - 1500 RPM.
7. Ice vanes - Retracted.
8. Aircraft weight - Refer to chart.
9. Allow conditions to stabilize for one minute
then record the following for each engine being
b. *Pressure altitude
