The conditions and calculations for our example flight are listed below. The takeoff and
landing distances required for our example flight have fallen well below the available runway
lengths.

NOTE
The remainder of the performance charts used in this flight plan
example assume a no wind condition. The effect of winds aloft
must be considered by the pilot when computing climb, cruise and
descent performance.
(c)
Climb
The next step in our flight plan is to determine the necessary climb segment components.
The desired cruise pressure altitude and corresponding cruise outside air temperature values
are the first variables to be considered in determining the climb components from the Time,
Distance, and Fuel to Climb graph (Figure 5-13). After the time, distance and fuel for the cruise
pressure altitude and outside air temperature values have been established, apply the existing
conditions at the departure field to graph (Figure 5-13). Now, subtract the values obtained from
the graph for the field of departure conditions from those for the cruise pressure altitude.
The remaining values are the true fuel, distance and time components for the climb segment
of the flight plan corrected for field pressure altitude and temperature.
The following values were determined from the above instructions in our flight planning
example.
