WT9 Dynamic weight and balance

Calculate loaded mass and centre of gravity using aircraft-specific weight-and-balance data.

Load

Basic empty mass (kg)

Use the current value from the aircraft records.

Pilot and passenger (kg)

Combined mass of the cockpit occupants.

Baggage (kg)

The default baggage limit is 10 kg.

Fuel (L)

Converted to mass using the entered fuel density.

Aircraft data and limits

These defaults reproduce the attached calculator. Confirm every value against the current approved data for the specific aircraft and variant.

Basic empty mass arm (mm)

Occupants arm (mm)

Baggage arm (mm)

Fuel arm (mm)

Fuel density (kg/L)

Maximum takeoff mass (kg)

Forward CG limit (mm)

Aft CG limit (mm)

Minimum cockpit load (kg)

Baggage limit (kg)

The calculator checks fixed forward and aft CG limits. Confirm whether the approved envelope for the aircraft varies with mass.

Planning aid only. This is not an approved load sheet. Before flight, verify the basic empty mass and arm, station arms, CG envelope, maximum mass, fuel density and loading limits using the current documents for the specific aircraft.
