1. Maximum
Continuous
Power
(MCPC)/Maximum Power Check (MPC):
a. Stabilize airspeed at 120 KIAS. with RRPM
100%.
b. Pilot’s or Copilot’s altimeter set to 29.92.
c. Determine required minimum TRQ for
Maximum Continous Power Check (MCPC)
from figure 5-11. (not to exceed 123%) and
the maximum continuous N1 speed from
figure 5-14 (Refer to Section V.) for MCPC.
d. Determine required minimum TRQ for
Maximum Power Check (MPC) from figure
5-12. (not to exceed 123%) and the
maximum N1 speed from figure 5-14 (Refer
to Section V.) for MPC.
e. ENG COND lever of engine not being
checked — Slowly retard towards GND until
the predetermined minimum required
torque (from step c - above) is attained.
Ensure that ENG PTIT for engine being
checked does not exceed the MCPC
temperature limit from figure 5-13 (Refer to
Section V.) or the maximum continuous N1
speed. If MCPC temperature limit or
maximum continuous N1 speed is reached
prior to required minimum TRQ being
attained, stop the PAC on this engine, and
proceed to step j.
f. Raise THRUST CONT lever once the ENG
COND lever is in the GND position, if
required, to obtain minimum TRQ while
ensuring the maximum PTIT or maximum
continuous N1 limits of figures 5-14 and
5-13 respectively (Refer to Section V) are
not exceeded.
