Level 1 Functional
Decomposition (concluded)

Fuel Moment (In: fuel) Out: Function value

Set moment = 0.0

Set fuelWt = fuel * 6.7

IF fuel < 60

Set fuelDistance = fuel * 314.6

ELSE IF fuel < 361

Set fuelDistance = 305.8 + (-0.01233 * (fuel – 60))

ELSE IF fuel < 521

Set fuelDistance = 303.0 + (0.12500 * (fuel – 361))

ELSE IF fuel < 521

Set fuelDistance = 323.0 + (-0.04444 * (fuel – 521))

Return fuelDistance * fuelWt
