Scheibe SF 25 C Falke weight and balance and performance calculator
Calculate the weight and balance of the Scheibe SF 25 C Falke online: enter people, baggage and fuel and get the takeoff mass, the CG and whether both are within the limits of the POH – plus the takeoff and landing distance for your airfield, temperature and wind. Free, no sign-up. The Scheibe SF 25 C Falke is a model of the Scheibe SF 25 Falke; build years not on file.

Calculate the Scheibe SF 25 C Falke 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.

Scheibe SF 25 C Falke 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 | 80 m (270 ft) | 205 m (670 ft) | – | – |
| 5,000 ft, 25 °C (density altitude ≈ 7,300 ft) | 125 m (410 ft) | 320 m (1,040 ft) | – | – |
Hot and high, the Scheibe SF 25 C Falke needs about 57 % more distance to clear 50 ft than at sea level. Calculate density altitude →

How to do the Scheibe SF 25 C Falke 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 Scheibe SF 25 C Falke. 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.

Scheibe SF 25 C Falke – frequently asked questions
What is the MTOW of the Scheibe SF 25 C Falke?
The maximum takeoff mass of the Scheibe SF 25 C Falke is 580 kg (1,279 lb) according to the POH.
How much usable fuel does the Scheibe SF 25 C Falke carry?
14.5 US gal (55 L) usable. With the typical POH empty mass and full fuel, about 132 kg (291 lb) remain for people and baggage.
How long is the takeoff distance of the Scheibe SF 25 C Falke?
At MTOW, sea level, 15 °C and no wind the ground roll is about 80 m (270 ft) and the distance over 50 ft about 205 m (670 ft). At 5,000 ft and 25 °C it grows to about 320 m (1,040 ft). The calculator above gives the value for your conditions.
How do I calculate the CG of the Scheibe SF 25 C Falke?
Multiply each mass by its arm, add up the moments and divide by the total mass – the calculator above does this with the stations of the Scheibe SF 25 C Falke POH (seat row 1, baggage compartment, fuel) and checks the CG against the envelope.
How does the Scheibe SF 25 C Falke differ from other Scheibe SF 25 Falke models?
BriefingPal has 2 Scheibe SF 25 Falke models on file. Compared with them the Scheibe SF 25 C Falke has the lowest MTOW (580 kg (1,279 lb)), 14.5 US gal (55 L) usable fuel and a takeoff distance over 50 ft of 205 m (670 ft) at MTOW.
Is the Scheibe SF 25 C Falke weight and balance calculator free?
Yes. The calculator on this page and the BriefingPal app are free and need no account. The app adds route planning, weather, NOTAM, fuel planning and a briefing PDF.
Data source
All figures come from the Pilot's Operating Handbook / Airplane Flight Manual of the Scheibe SF 25 C Falke (weight and balance and performance sections) and are computed with the BriefingPal engine – the same calculation as in the app. Planning aid only; the original POH/AFM and the weighing report of your aircraft remain authoritative.
