NOTE
Engine operations which exceed 740" C ITT may reduce
engine life.
To achieve maximum flat-rated horsepower, use a
minimum of 1800 RPM.

If an obstruction dictates the use of
a
steep climb angle, climb with flaps
retracted and maximum continuous power at
72
KIAS.
CRUISE
Normal cruising is performed using any desired power setting up to the
maximum cruise power (observe
ITT, torque, and
N
cruise limits). Do
not exceed the maximum cruise torque shown
in?Section
5
for the
particular altitude and temperature. Normally, a new engine will exhibit
I
an ITT below 710'C when set to the maximum cruise torque.

The Sample Cruise Performance Table, Figure
4-4,
illustrates the
advantage of higher altitude on both true airspeed and nautical miles
per pound of fuel. In addition, the beneficial effect of lower cruise power
on nautical miles per pound at a given altitude can be observed. Charts
are Drovided in Section 5 to assist in selectina an efficient altitude
based on ava
lable winds aloft nformat~on for a gken trip. The selection
of cruise altitude on
the basis of the most favorable wind condit~ons and
the use of low power settings are significant factors that should be
considered on every trip to reduce fuel consumption.
