Calculate the Bristell NG-5 / LSA (912 ULS) 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 NG-5 / LSA (912 ULS) 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 | 200 m (660 ft) | 455 m (1,500 ft) | 290 m (950 ft) | 90 m (300 ft) |
| 5,000 ft, 25 °C (density altitude ≈ 7,300 ft) | 310 m (1,020 ft) | 710 m (2,320 ft) | – | – |
Hot and high, the Bristell NG-5 / LSA (912 ULS) needs about 55 % more distance to clear 50 ft than at sea level. Calculate density altitude →

How to do the Bristell NG-5 / LSA (912 ULS) 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 NG-5 / LSA (912 ULS). 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.
