5-5-1-1
General
This section gives an example of flight planning for aircraft with a five bladed propeller. Before
performance calculations can begin, it will be necessary to determine the aircraft loading.
Refer to Section 6, Weight and Balance to calculate the actual aircraft loading.

Takeoff
Apply the departure airport conditions and the aircraft weight to the appropriate takeoff
performance charts and check that the corresponding distances are less than the available
field length at the departure airport.
Apply the departure airport conditions to the Takeoff Power Chart to determine maximum
torque to be applied before brake release.
5-5-1-3
Climb
Note
The climb performance chart assumes a no wind condition. The pilot must consider the
effect of the winds aloft when computing time, fuel, and distance to climb. The fuel to
climb includes the fuel consumed during the takeoff run.
Apply the cruise conditions of pressure altitude and temperature (respectively 28000 ft and ISA
+10 °C in this case) to the appropriate chart to determine the time, fuel, and distance to climb
from sea level to the cruise altitude at the specified takeoff weight (8798 lb in this case). Next,
apply the departure airport conditions (respectively 4000 ft and ISA +10 °C in this case) to the
same chart to determine those same values to climb from sea level to the departure airport.
Subtract the values for the departure airport from those for the cruise altitude. The remaining
values are the time, fuel, and distance to climb from the departure airport to the cruise altitude.
