Example:
A Maximum Continuous Power Check / Maximum Power
Check were performed under Ambient Conditions of
Altitude — 4,000 feet; Temperature = +10_C.
NOTE
Engine No. 2 defines an engine failing the Maxi-
mum Continuous Power Check.
FAT = +10_C
PA = 4,000 feet

The above example illustrates the minimum acceptable
torque for the MCPC is 97% and the minimum accept-
able torque for MPC is 111%. The recorded datum
shows both Engine #1 and Engine #2 were at the mini-
mum torque required.
