In 1994 the U.S. National Institute of Standards and Technology (NIST) introduced gasoline gallon equivalent (GGE) as a metric for fuel economy for natural gas vehicles. NIST defined a gasoline gallon equivalent (GGE) as 5.660 pounds of natural gas, and gasoline liter equivalent (GLE) as 0.678 kilograms of natural gas
NOTE:
Be sure to take into consideration winds aloft, restricted zones, climb time and fuel for a margin of safety when calculating requirements. Be sure to check the current NOAA aviation weather for departure, along the flight plan and at the destination airport before departure. Free online Mechanical engineering Calculators.
Example:
Calculate the Gallon per hour fuel consumption by the given details.
Enter Fuel Capacity in Gallons for All Tanks = 15
Enter Trip Time Elapsed In Hours = 25
Enter Starting Fuel In Gallons In All Tanks = 10
Enter Ending Fuel In Gallons In All Tanks = 5
Solution:
Apply Formula:
Aviation Gasoline weight per gallon (gw) =6.00
Jet A weight per gallon (dw) =6.84
Total Capacity (AvGas) Fuel Load Weight=(Fuel weight)* (gw)
GPH=start fuelend fuel
Aviation Gasoline weight per gallon (gw) =6.00
Jet A weight per gallon (dw) =6.84
