Reserve Fuel is calculated for 45 minutes at Maximum
Range Power @ 1700 RPM. Use planned cruise
altitude (26,000 feet), forecasted ISA condition (ISA +
17°C), and estimated weight at end of planned trip
(10,153 pounds). (Since the lowest weight column in
the tables is 11,000 pounds, assume weight at the end
of the planned trip to be 11,000 pounds, and use that
fuel flow value for this example.)
Enter the tables for MAXIMUM RANGE POWER @
1700 RPM for ISA + 10°C and ISA + 20°C at 11,000 Lbs
and 26,000 feet, and read the total fuel flows:
ISA + 10°C ........................................ 454 Lbs/hr
ISA + 20°C ........................................ 466 Lbs/hr
