SPECIFIC RANGE
(SPCRANGE)
Specific range is a planning function used to determine the
most desirable altitude for long range flight. Range is
calculated in miles given the total fuel, groundspeed and
fuel burn. In this example, we will compute aircraft range at
12,000 feet with 140 gallons of fuel. Our fuel burn will be
24 gallons per hour with a groundspeed of 150.
