Scheibe SF 25 Falke weight and balance and performance calculator
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.

¹ Typical empty mass from the POH sample loading; your aircraft's current weighing report applies. Useful load = MTOW − empty mass − usable fuel (people, baggage, oil if not included).
Scheibe SF 25 Falke takeoff and landing distance
BriefingPal result at MTOW, sea level, 15 °C, no wind, dry paved runway, normal takeoff and landing per POH with the app's default flap setting, without safety factor:
| Model | Takeoff ground roll | Takeoff over 50 ft | Landing over 50 ft | Landing ground roll |
|---|---|---|---|---|
| SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop) | 80 m (270 ft) | 205 m (670 ft) | – | – |
| SF 25 C Rotax-Falke (Rotax 912 A, Verstellprop. MTV-1-A, 650 kg) | 140 m (460 ft) | 270 m (880 ft) | – | – |
Hot and high: at 5,000 ft and 25 °C (density altitude about 7,300 ft) the SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop) needs about 320 m (1,040 ft) to clear 50 ft – 57 % more than at sea level. Calculate density altitude →
In BriefingPal you enter your actual weight, airfield, temperature and wind. The app reads the POH charts for these conditions, compares the result with TORA/LDA of the selected runway and can add a 1.15 safety factor.
Scheibe SF 25 Falke climb and cruise performance
| Model | Rate of climb at sea level | Time / fuel to 6,500 ft | Cruise TAS at 6,500 ft | Fuel flow |
|---|---|---|---|---|
| SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop) | 630 fpm | 13 min / 1.7 US gal | 78 kt | 3.4 US gal/h (13 L/h) |
| SF 25 C Rotax-Falke (Rotax 912 A, Verstellprop. MTV-1-A, 650 kg) | 940 fpm | 10 min / 1.3 US gal | 81 kt | 3.8 US gal/h (14 L/h) |
MTOW, ISA, default power setting of the POH cruise table. Values change with weight, temperature and the power you choose in the app.

How to calculate Scheibe SF 25 Falke weight and balance
- Choose the Scheibe SF 25 FalkeType the registration or pick Scheibe → Scheibe SF 25 Falke → your model. Stored weighing data of the registration are used automatically.
- Enter people, baggage and fuelWeights in kg or lb, fuel in US gallons or litres. MTOW and every station limit are checked instantly.
- Check the CG envelopeTakeoff, zero-fuel and landing points are drawn into the Scheibe SF 25 Falke envelope from the POH.
- Add airfields and routeTakeoff and landing distances, climb, cruise and fuel follow from the same weight – then print the briefing PDF.
Scheibe SF 25 Falke – frequently asked questions
What is the maximum takeoff weight (MTOW) of the Scheibe SF 25 Falke?
Depending on the model, SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop): 580 kg (1,279 lb); SF 25 C Rotax-Falke (Rotax 912 A, Verstellprop. MTV-1-A, 650 kg): 650 kg (1,433 lb).
How much usable fuel does the Scheibe SF 25 Falke carry?
Usable fuel per POH: SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop): 14.5 US gal (55 L); SF 25 C Rotax-Falke (Rotax 912 A, Verstellprop. MTV-1-A, 650 kg): 14.5 US gal (55 L).
What is the useful load of the Scheibe SF 25 Falke with full fuel?
With the typical POH empty mass and full usable fuel: SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop): 132 kg (291 lb); SF 25 C Rotax-Falke (Rotax 912 A, Verstellprop.

How long is the Scheibe SF 25 Falke takeoff distance?
SF 25 C Falke (Limbach L 2000 EA, fixed-pitch prop) at MTOW, sea level, 15 °C, no wind: ground roll about 80 m (270 ft), over 50 ft about 205 m (670 ft). At 5,000 ft and 25 °C it grows to about 320 m (1,040 ft). Always check the POH for your exact conditions.
Is there a free Scheibe SF 25 Falke weight and balance calculator?
Yes. BriefingPal is free and needs no account. It covers 2 models of the Scheibe SF 25 Falke, draws the CG envelope from the POH and also computes takeoff and landing distances, climb, cruise and fuel – with a briefing PDF.
Data source
All figures come from the manufacturer's Pilot's Operating Handbook / Airplane Flight Manual of each model (weight and balance section and performance section) and are computed with the BriefingPal engine. BriefingPal is a planning aid; the original POH/AFM of your aircraft and its weighing report remain authoritative.
