FLIGHT CHECKS (CONT)
f. If a 2% droop is not achieved, do
(1) Increase collective pitch while
maintaining approximately 60%
torque on the non-test engine
until a reduction of 2%
ENG-RTR RPM is observed.
(2) Maintain a constant pressure
altitude by adjusting forward
airspeed as necessary.
g. If a 2% droop is still not achieved,
go to step 8.1.
When the engine is TGT limited, the TGT
may momentarily exceed the normal dual
engine TGT limiter setting.
h. Observe TGT on the test engine. If
TGT does not stabilize at the
normal dual engine TGT limit in 10
to 15 seconds after the last
collective pitch or PWR lever input,
discontinue the maximum power
i. Slowly reduce collective pitch or
advance the PWR lever on the
non-test engine to re-establish
ENG-RTR RPM at 100%
j. Wait 30 seconds and record
airspeed (KIAS), NG (%),
TGT (C), torque (%), OAT (C),
and pressure altitude (ft).
