Unlimited Fuel

Set CZH_fuelBurnLPH = 0 to disable fuel consumption entirely.

Custom Flight Duration Formula

CZH_fuelBurnLPH = (CZH_maxFuel / desired_flight_minutes) * 60
Example — UH-1H for exactly 1 hour of flight:
CZH_fuelBurnLPH = (833 / 60) * 60 = 833

Fuel Warning System

Audio warning beeps alert the crew when fuel is running low:
  • Beeps begin at the configured fuel fraction threshold
  • The beep interval shortens as fuel continues to drop — urgency increases
  • Both pilot and co-pilot hear the warning
