CRUISE
The cruising altitude should be selected based on a
consideration of trip length, winds aloft, and the airplane's
performance. A typical cruising altitude and the expected wind
enroute have been given for this sample problem. However, the
power setting selection for cruise must be determined based on
several considerations. These include the cruise performance
characteristics presented in Figure 5-9, the range profile chart
presented in Figure 5-10, and the endurance profile chart presented
in Figure 5-11.
The relationship between power and range is illustrated by the
range profile chart. Considerable fuel savings and longer range
result when lower power settings are used. For this sample
problem, a cruise power of approximately 60% will be used.
The cruise performance chart, Figure 5-9, is entered at 8000 feet
pressure altitude and 20°C above standard temperature. These
values most nearly correspond to the planned altitude and expected
temperature conditions. The engine speed chosen is 2400 RPM
and 19 inches of manifold pressure, which results in the following:
Power 60%
True airspeed 130 Knots
Cruise fuel flow 10.7 GPH
