Choose the exact Mooney model below. Different Mooney M20 variants can use different maximum weights, center-of-gravity envelopes, fuel capacities, seat positions and baggage loading stations.

The Mooney M20 family includes several certified variants with different loading data. Maximum aircraft weight, center-of-gravity limits, usable fuel, seating positions and baggage stations can vary between individual models.
For that reason, WBcalc provides separate model-specific calculators rather than treating every Mooney M20 as one generic aircraft configuration.
A weight and balance calculation must use data that applies to the actual aircraft configuration. Two airplanes from the same model family can have different approved limits, and equipment changes or modifications can also affect the current aircraft weight and balance record.
Choose the exact Mooney model above and then verify the represented configuration against the applicable POH or AFM and the current documentation for the individual airplane.
Maximum aircraft weight and center of gravity are separate limitations. An airplane can remain below its maximum permitted weight while its loaded CG is too far forward or too far aft.
The individual Mooney calculator pages use the forward and aft CG limits represented by their model-specific aircraft data. Where a published limit changes between weight points, the calculator can interpolate between the applicable breakpoints.
Fuel contributes both weight and moment. The usable fuel quantity and fuel arm represented by each calculator can differ between Mooney variants and configurations.
Because fuel burn removes both weight and moment, the aircraft center of gravity can move during flight depending on the location of the fuel relative to the aircraft datum.
Some Mooney models use adjustable seat-position ranges rather than one universal seat arm. When a calculator asks for the actual seat arm, use the applicable loading position from the aircraft loading information.
Passenger loading affects both total aircraft weight and moment, so seat position can have a meaningful effect on the final center-of-gravity result.
Baggage limitations must be checked independently of maximum aircraft weight. Depending on the model, baggage or aft storage areas can have their own weight limits and loading arms.
A loading that is below maximum takeoff weight can still be unacceptable if a baggage limit is exceeded or if the resulting center of gravity is outside the approved envelope.
Use the current basic empty weight and empty CG or arm from the certified weight and balance record for the individual aircraft.
Do not use a generic Mooney empty weight simply because another airplane is the same model. Avionics, equipment, interiors, paint, repairs and approved modifications can change the empty weight and empty CG during the life of the aircraft.
No. Different M20 variants can use different maximum weights, CG envelopes, fuel quantities, seating positions and baggage loading data.
Use the calculator that matches the exact aircraft model and verify that the represented configuration applies to the individual airplane.
Yes. Maximum aircraft weight and center-of-gravity limits are separate requirements, and both must be satisfied.
No. Use the current certified basic empty weight and empty CG or arm from the individual aircraft weight and balance record.
Yes. Fuel contributes both weight and moment, so changing fuel quantity can change the loaded center of gravity.
No. WBcalc is a planning and calculation aid. The approved POH or AFM, current aircraft weight and balance record, equipment list, supplements and other applicable approved documents remain authoritative.
