Calculate the Socata Rallye Club MS.880B weight, CG and takeoff distance
Your own empty mass (weighing report, optional)
The POH has no standard empty moment for this model – enter the empty mass CG from your weighing report to get the CG.
Leave empty to use the typical POH empty mass. Your aircraft's weighing report is what counts.
Calculated on the BriefingPal server from the POH data. Nothing is stored, no cookie. Planning aid only – the POH/AFM and your weighing report are authoritative.

How to do the Socata Rallye Club MS.880B weight and balance
- Enter the loadingWeights of pilot, passengers and baggage per station, fuel in litres or US gallons. Each station limit and the MTOW are checked.
- Use your own empty massOptional: enter empty mass and empty CG from the weighing report of your Socata Rallye Club MS.880B. Without it the typical POH empty mass is used.
- Check CG and massThe traffic light shows whether the takeoff mass and the CG with and without fuel lie within the envelope of the POH.
- Takeoff and landingElevation, QNH, temperature, wind and runway give the takeoff and landing distance – compared with the runway length if you enter it.
