*D. Speed Check at Maximum Cruise 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 re-
tracted, if cruise torque settings shown on
the cruise power charts should be obtained
without exceeding TGT limits.
Sped-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 power
and speed charts (figure 9 through 14).
1. Record the following:
*a. Engine serial number
*b. Engine hours since new
*c. Engine hours since overhaul
* 2. Airspeed - Refer to chart.
* 3. Altitude - Refer to chart.
* 4. FAT - Refer to chart.
5. Power setting - Refer to chart.
6. Propeller RPM - Refer to chart.
7. Ice vanes - Retracted.
8. Aircraft weight - Refer to chart.
For engines that exceed 730°C TGT, engine
acceptance at maximum cruise power, must
