CG Reference Calculator - SimPayloads
Calculate and visualize center of gravity (CG) for your flight simulation aircraft. Our free CG calculator helps virtual pilots ensure their aircraft is properly balanced for safe flight operations.
Supported Aircraft
- PMDG 737-700 for MSFS
- PMDG 737-800 for MSFS
- iFly 737 MAX 8 for MSFS
- More aircraft coming soon
CG Phases Calculated
- ZFW CG (Zero Fuel Weight) - CG position before fuel is added
- TOW CG (Takeoff Weight) - CG position at takeoff with full fuel load
- LDG CG (Landing Weight) - CG position at landing after fuel burn
How It Works
- Select your aircraft type
- Enter forward and aft cargo weights
- Enter passenger count
- Enter total fuel and trip fuel
- View your CG position on the envelope visualization
