Fuel Required - Cessna 182T 2001 Pilot Operating Handbook

SECTION 5
PERFORMANCE

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, Figure 5-8 shows that a normal climb from 2000
feet to 8000 feet requires 2.7 gallons of fuel. The corresponding
distance during the climb is 18 nautical miles. 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 non-standard temperature is to increase the
time, fuel, and distance by 10% for each 10°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:
16° X 10% = 16% Increase
10°C
With this factor included, the fuel estimate would be calculated as
follows:
Fuel to climb, standard temperature
Increase due to non-standard temperature
(2.7 X 16%)
Corrected fuel to climb
Using a similar procedure for the distance to climb results in 21
nautical miles.
The resultant cruise distance is:
