Calculate the Bristell B23-915 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.

Bristell B23-915 takeoff and landing distance
BriefingPal result from the POH charts at MTOW, no wind, dry paved runway, normal procedure, default flap setting, without safety factor. Use the calculator above for your mass, airfield, temperature and wind.
| Conditions | Takeoff ground roll | Takeoff over 50 ft | Landing over 50 ft | Landing ground roll |
|---|---|---|---|---|
| Sea level, 15 °C | 175 m (580 ft) | 330 m (1,090 ft) | 390 m (1,280 ft) | 145 m (480 ft) |

How to do the Bristell B23-915 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 Bristell B23-915. 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.
