Calculate the Mooney M20C Mark 21/Ranger 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.

Mooney M20C Mark 21/Ranger 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 | 250 m (820 ft) | 425 m (1,400 ft) | 470 m (1,550 ft) | 180 m (590 ft) |
| 5,000 ft, 25 °C (density altitude ≈ 7,300 ft) | 570 m (1,870 ft) | 975 m (3,200 ft) | – | – |
Hot and high, the Mooney M20C Mark 21/Ranger needs about 129 % more distance to clear 50 ft than at sea level. Calculate density altitude →

How to do the Mooney M20C Mark 21/Ranger 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 Mooney M20C Mark 21/Ranger. 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.

Mooney M20C Mark 21/Ranger – frequently asked questions
What is the MTOW of the Mooney M20C Mark 21/Ranger?
The maximum takeoff mass of the Mooney M20C Mark 21/Ranger is 1,168 kg (2,575 lb) according to the POH.
How much usable fuel does the Mooney M20C Mark 21/Ranger carry?
52 US gal (197 L) usable. With the typical POH empty mass and full fuel, about 335 kg (738 lb) remain for people and baggage.
How long is the takeoff distance of the Mooney M20C Mark 21/Ranger?
At MTOW, sea level, 15 °C and no wind the ground roll is about 250 m (820 ft) and the distance over 50 ft about 425 m (1,400 ft). At 5,000 ft and 25 °C it grows to about 975 m (3,200 ft). The calculator above gives the value for your conditions.
How do I calculate the CG of the Mooney M20C Mark 21/Ranger?
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 Mooney M20C Mark 21/Ranger POH (front seats, rear seats, baggage compartment, hat shelf / rear baggage, fuel) and checks the CG against the envelope.
How does the Mooney M20C Mark 21/Ranger differ from other Mooney M20J models?
BriefingPal has 4 Mooney M20J models on file. Compared with them the Mooney M20C Mark 21/Ranger has the lowest MTOW (1,168 kg (2,575 lb)), 52 US gal (197 L) usable fuel and a takeoff distance over 50 ft of 425 m (1,400 ft) at MTOW.
Is the Mooney M20C Mark 21/Ranger 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 Mooney M20C Mark 21/Ranger (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.
