*8. Maximum power check Perform as
follows:
WARNING
A safe AGL altitude must be maintained
to allow sufficient reaction time if the en-
gine being tested fails, or if other emer-
gency situations occur.
CAUTION
To avoid torque oscillations when mak-
ing performance checks, a torque split of
at least 10% will be held between en-
gines.
a. Establish a climb at 100% dual
engine torque. Periodic collective
control increase will be required
throughout the climb to maintain
100% torque. Continue climb at
100% torque until one of the three
following conditions occur:
