Reserve fuel Solution

STEP 0: Pre-Calculation Summary
Formula Used
Reserve fuel = Fuel load-Mission fuel
Wresf = Wf-Wmisf
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: 8823 Kilogram --> 8823 Kilogram No Conversion Required
Mission fuel: 8761 Kilogram --> 8761 Kilogram No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
Wresf = Wf-Wmisf --> 8823-8761
Evaluating ... ...
Wresf = 62
STEP 3: Convert Result to Output's Unit
62 Kilogram --> No Conversion Required
FINAL ANSWER
62 Kilogram <-- Reserve fuel
