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
en route 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
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 21 inches
of manifold pressure, which results in the following:
