Reserve Fuel Solution

STEP 0: Pre-Calculation Summary

Formula Used

Reserve Fuel = Fuel Load-Mission Fuel
W_resf = W_f-W_misf
This formula uses 3 Variables

Variables Used

Reserve Fuel - (Measured in Kilogram) - Reserve Fuel for manoeuvring, holding, aborting the landing and making a diversion flight.
Fuel Load - (Measured in Kilogram) - Fuel Load may be available fuel (consumable fuel) or total fuel and is usually dry weight.
Mission Fuel - (Measured in Kilogram) - Mission Fuel is that fuel at the time of take-off.

STEP 1: Convert Input(s) to Base Unit

Fuel Load: 9499 Kilogram --> 9499 Kilogram No Conversion Required
Mission Fuel: 8761 Kilogram --> 8761 Kilogram No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W_resf = W_f-W_misf --> 9499-8761

Evaluating ... ...

W_resf = 738

STEP 3: Convert Result to Output's Unit

738 Kilogram --> No Conversion Required

FINAL ANSWER

738 Kilogram <-- Reserve Fuel

What is reserve fuel in aviation?

Final reserve fuel is the minimum fuel required to fly for 30 minutes at 1,500 feet above the alternate aerodrome or, if an alternate is not required, at the destination aerodrome at holding speed in ISA conditions.

How to Calculate Reserve Fuel?

Reserve Fuel calculator uses Reserve Fuel = Fuel Load-Mission Fuel to calculate the Reserve Fuel, Reserve Fuel formula refers to an additional quantity of fuel carried on aircraft to accommodate unexpected events or deviations from the planned flight, it ensures that the aircraft has sufficient fuel to complete the journey safely and land at the intended destination with an appropriate margin of safety. Reserve Fuel is denoted by W_resf symbol.

How to calculate Reserve Fuel using this online calculator? To use this online calculator for Reserve Fuel, enter Fuel Load (W_f) & Mission Fuel (W_misf) and hit the calculate button. Here is how the Reserve Fuel calculation can be explained with given input values -> 62 = 9499-8761.

FAQ

What is Reserve Fuel?

Reserve Fuel formula refers to an additional quantity of fuel carried on aircraft to accommodate unexpected events or deviations from the planned flight, it ensures that the aircraft has sufficient fuel to complete the journey safely and land at the intended destination with an appropriate margin of safety and is represented as W_resf = W_f-W_misf or Reserve Fuel = Fuel Load-Mission Fuel. Fuel Load may be available fuel (consumable fuel) or total fuel and is usually dry weight & Mission Fuel is that fuel at the time of take-off.

How to calculate Reserve Fuel?

Reserve Fuel formula refers to an additional quantity of fuel carried on aircraft to accommodate unexpected events or deviations from the planned flight, it ensures that the aircraft has sufficient fuel to complete the journey safely and land at the intended destination with an appropriate margin of safety is calculated using Reserve Fuel = Fuel Load-Mission Fuel. To calculate Reserve Fuel, you need Fuel Load (W_f) & Mission Fuel (W_misf). With our tool, you need to enter the respective value for Fuel Load & Mission Fuel and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
