Loading
Your own empty mass (weighing report, optional)

Leave empty to use the typical POH empty mass. Your aircraft's weighing report is what counts.

How to do the Grumman AA-1 Yankee weight and balance

  1. Enter the loadingWeights of pilot, passengers and baggage per station, fuel in litres or US gallons. Each station limit and the MTOW are checked.
  2. Use your own empty massOptional: enter empty mass and empty CG from the weighing report of your Grumman AA-1 Yankee. Without it the typical POH empty mass is used.
  3. 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.
  4. Takeoff and landingElevation, QNH, temperature, wind and runway give the takeoff and landing distance – compared with the runway length if you enter it.

Grumman AA-1 Yankee – frequently asked questions

What is the MTOW of the Grumman AA-1 Yankee?

The maximum takeoff mass of the Grumman AA-1 Yankee is 680 kg (1,500 lb) according to the POH.

How much usable fuel does the Grumman AA-1 Yankee carry?

22 US gal (83 L) usable (total capacity 24 US gal (91 L)). With the typical POH empty mass and full fuel, about 164 kg (361 lb) remain for people and baggage.

How long is the takeoff distance of the Grumman AA-1 Yankee?

At MTOW, sea level, 15 °C and no wind the ground roll is about 275 m (900 ft) and the distance over 50 ft about 490 m (1,620 ft). At 5,000 ft and 25 °C it grows to about 1,000 m (3,280 ft). The calculator above gives the value for your conditions.

How do I calculate the CG of the Grumman AA-1 Yankee?

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 Grumman AA-1 Yankee POH (front seats, baggage compartment, fuel) and checks the CG against the envelope.

How does the Grumman AA-1 Yankee differ from other Grumman AA-1 Yankee/Trainer models?

BriefingPal has 4 Grumman AA-1 Yankee/Trainer models on file. Compared with them the Grumman AA-1 Yankee has the lowest MTOW (680 kg (1,500 lb)), 22 US gal (83 L) usable fuel and a takeoff distance over 50 ft of 490 m (1,620 ft) at MTOW.

Is the Grumman AA-1 Yankee 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 Grumman AA-1 Yankee (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.
