SAMPLE PROBLEM
(Continued)
FUEL REQUIRED
The total fuel requirement for the flight may be estimated using the
performance information in Figure 5-8 and Figure 5-9. For this sample
problem, the time, fuel and distance to climb may be determined from
Figure 5-8 for normal climb. The difference between the values shown
in the table for 4000 feet and 12,000 feet results in the following:
These values are for a standard temperature and are sufficiently
accurate for most flight planning purposes. However, a further
correction for the effect of temperature may be made as noted on the
climb chart. The approximate effect of a nonstandard temperature is to
increase the time, fuel and distance by 10% for each 8°C above
standard temperature, due to the lower rate of climb. In this case,
assuming a temperature 16°C above standard the correction would be:
With this factor included, the fuel estimate would be calculated as
follows:
Using a similar procedure for the distance to climb results in 36 nautical
miles.
The resultant cruise distance is:

Time: 17 Minutes
Fuel: 4.3 Gallons
Distance: 30 Nautical Miles
16°C X 10% = 20% Increase
8°C
Fuel to climb, standard temperature 4.3 Gallons
Increase due to non-standard temperature (4.3 X 20%) 0.9 Gallons
Corrected fuel to climb 5.2 Gallons
Total distance 450 Nautical Miles
Climb distance -36 Nautical Miles
Cruise distance 414 Nautical Miles
