Calculate the Cessna 170 (1948-51) 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.

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 | 220 m (730 ft) | 555 m (1,810 ft) | 535 m (1,750 ft) | 240 m (790 ft) |

How to do the Cessna 170 (1948-51) 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 Cessna 170 (1948-51). 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.

37 US gal (140 L) usable. With the typical POH empty mass and full fuel, about 344 kg (758 lb) remain for people and baggage.
How long is the takeoff distance of the Cessna 170 (1948-51)?
At MTOW, sea level, 15 °C and no wind the ground roll is about 220 m (730 ft) and the distance over 50 ft about 555 m (1,810 ft). At 5,000 ft and 25 °C it grows to about 930 m (3,040 ft). The calculator above gives the value for your conditions.
How do I calculate the CG of the Cessna 170 (1948-51)?
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 Cessna 170 (1948-51) POH (front seats, rear seats, baggage compartment, fuel) and checks the CG against the envelope.
How does the Cessna 170 (1948-51) differ from other Cessna 170 models?
BriefingPal has 2 Cessna 170 models on file. Compared with them the Cessna 170 (1948-51) has an MTOW of 998 kg (2,200 lb) (range 998–998 kg), 37 US gal (140 L) usable fuel and a takeoff distance over 50 ft of 555 m (1,810 ft) at MTOW.
Is the Cessna 170 (1948-51) 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 Cessna 170 (1948-51) (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.
