SAMPLE PROBLEM
(Continued)
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 70% will be used.
The cruise performance chart, Figure 5-9, is entered at 12,000 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 24
inches of manifold pressure, which results in the following:
