Additional Operations
and Performance Data
Original
9–4
9–2. FUEL FLOW vs AIRSPEED
Description:
The fuel flow charts presented in this section are based on level flight
performance data. Fuel consumption values are based on minimum specification
engines and thus may vary between engines. This data is based on a baseline aircraft
with 15% electrical load, engine bleeds and air conditioner off.
Use of Chart:
Use the charts as illustrated by the example below.
NOTE
: The following example uses Figure 9–1.
Example
:
Wanted: Rate of fuel flow
Known: Airspeed = 115 KIAS
Known: Estimated gross weight = 5500 pounds
Method: Enter the chart at the known airspeed of 115 knots (interpolation re
quired). Move vertically to the 5500 pound point (interpolation required)
then move to the left to the fuel flow scale and read a fuel flow of approxi
mately 440 LB/HR.
