engine operation table -- Chapter 5.7
to Cruise index on the PFD’s
As indicated in lower part of these tables, reduce propeller RPM is
possible (without touching power lever), in order to improve sound
comfort without significant performance change (speed,
consumption). However, at the time of this setting, limit permitted by
torque limiter may be reached. This limit is 110 % at sea level and
drops to about 100 % at 30000 ft. Therefore, any propeller RPM
reducing performed in altitude from a torque close to 100 % (if ITT
limit permits it) will be followed by a non--negligible power (and
performance) decrease owing to torque limiter.
CAUTION
OBSERVE TRQ / Ng / Np / ITT / T
°
AND OIL PRESSURE LIMITATIONS
USE OPTIMUM TORQUE AND / OR REFER TO
TABLES IN CHAPTER 5.7
Engine operation tables (Chapter 5.7) give torque to be applied
according to OAT, in order not to exceed authorized maximum
power.
When ”INERT SEP” switch is OFF, a more accurate setting of
power must then be performed according to cruise performance
tables presented in Chapter 5.10.
