FLIGHT CHECKS (CONT)
e. While maintaining no greater than
75% torque on the non-test engine
increase collective as required to
reach a TGT Limiter Setting and a
2% Nr/Np droop, or a single engine
torque limit, whichever comes first.
f. Record TGT and torque (allow 10
seconds for indications to stabilize).
Indicated TGT must be between 851 - 869
, 857 - 875 C
g. Collective Reduce until the
combined torques of both engines
is less than the torque of the test
engine when TGT limiting was
Failure to reduce collective to less than
the value noted in step g. could cause
Nr/Np droop when step h. is completed.
h. PWR lever, non test engine
Retard to IDLE.
i. Collective Increase as required to
reach a TGT indication of
approximately 10 C above the
TGT limiter setting determined in
