RQ = \frac{CO_2\ produced}{O_2\ consumed}

Ratio revealing which fuel is being metabolised.

RQ = \frac{CO_2\text{ produced}}{O_2\text{ consumed}}

Ratio revealing which fuel is being metabolized.

F = \dot{f} \times t

Total fuel needed is the fuel-burn rate multiplied by flight time.

V_{up} = \dfrac{F_{req} - F_{OB}}{\rho}

Fuel to be loaded: the required ramp/block fuel minus fuel already on board, converted from mass to volume using fuel density.

SR = \dfrac{GS}{\dot{f}}

Distance flown per unit of fuel; maximizing it gives best fuel economy.

R = \dfrac{V}{c}\dfrac{L}{D}\ln\dfrac{W_i}{W_f}

Maximum range of a jet aircraft from speed, efficiency, L/D and fuel fraction.

E = \frac{\text{fuel}}{\text{fuel flow}}

Time an aircraft can stay airborne.

\text{mpg} = \frac{\text{Miles}}{\text{Gallons}}

Distance traveled per gallon of fuel.

\text{Cost} = \frac{D}{E} \times p

Total fuel cost for a trip.
