Calculate the Robin DR 401-155CDI 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.

How to do the Robin DR 401-155CDI 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 Robin DR 401-155CDI. 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.

What is the MTOW of the Robin DR 401-155CDI?
The maximum takeoff mass of the Robin DR 401-155CDI is 1,100 kg (2,425 lb) according to the POH.
How much usable fuel does the Robin DR 401-155CDI carry?
28.7 US gal (109 L) usable (total capacity 29 US gal (110 L)). With the typical POH empty mass and full fuel, about 413 kg (910 lb) remain for people and baggage.
How long is the takeoff distance of the Robin DR 401-155CDI?
At MTOW, sea level, 15 °C and no wind the ground roll is about 215 m (700 ft) and the distance over 50 ft about 400 m (1,310 ft). At 5,000 ft and 25 °C it grows to about 615 m (2,030 ft). The calculator above gives the value for your conditions.
How do I calculate the CG of the Robin DR 401-155CDI?
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 Robin DR 401-155CDI POH (seat row 1, seat row 2, baggage compartment, fuel) and checks the CG against the envelope.
How does the Robin DR 401-155CDI differ from other Robin DR 400 models?
BriefingPal has 11 Robin DR 400 models on file. Compared with them the Robin DR 401-155CDI has an MTOW of 1,100 kg (2,425 lb) (range 865–1,150 kg), 28.7 US gal (109 L) usable fuel and a takeoff distance over 50 ft of 400 m (1,310 ft) at MTOW.
Is the Robin DR 401-155CDI 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 Robin DR 401-155CDI (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.
