Piper PA-28R-201 Arrow weight and balance calculator
Enter the empty weight and CG from your aircraft's weight-and-balance record, then the people, baggage and fuel. The calculator works out the moment for each station, the takeoff, landing and zero-fuel CG, and plots them on the Piper PA-28R-201 Arrow CG envelope.
Sample data: these PA-28R-201 numbers are representative values that have not yet been checked line by line against the POH. Use your POH for real loading decisions.
| Station | Weight | Arm (in) | Moment |
|---|---|---|---|
| Basic empty weight | 150,500 | ||
| Pilot and front passenger | 80.5 | 27,370 | |
| Rear passengers | 118.1 | 0 | |
| Baggagemax 200 lb | 142.8 | 2,856 | |
| Fuel (usable) | = 240 lb (6 lb/gal) | 95.0 | 22,800 |
| Takeoff | 2,320 lb | 87.73 | 203,526 |
| Landingburn | 2,248 lb | 87.49 | 196,686 |
| Zero fuel | 2,080 lb | 86.89 | 180,726 |
CG = total moment ÷ total weight = 203,526 ÷ 2,320 = 87.73 in.
Piper PA-28R-201 Arrow loading stations
Representative values (Arrow III / IV): front seats at 80.5 in, rear seats 118.1, fuel at 95 (72 gal usable), baggage at 142.8 (200 lb), maximum weight 2,750 lb. The forward-limit corner points have not yet been cross-checked against the POH.
| Station | Arm (in aft of datum) | Limit |
|---|---|---|
| Basic empty weight | from your W&B record | — |
| Pilot and front passenger | 80.5 | — |
| Rear passengers | 118.1 | — |
| Baggage | 142.8 | 200 lb |
| Fuel (usable) | 95.0 | 72 gal usable |
Piper PA-28R-201 Arrow CG envelope
Normal category — maximum 2,750 lb
- Forward limit: 82.0 in from 1,400 to 2,100 lb, then a straight line to 90.0 in at 2,750 lb.
- Aft limit: 93.0 in at all weights.
Worked example
With the sample numbers above — pilot and front passenger 340 lb, baggage 20 lb, fuel (usable) 240 lb and an empty weight of 1,720 lb at 87.5 in:
- Moments: 1,720 × 87.5 = 150,500; 340 × 80.5 = 27,370; 20 × 142.8 = 2,856; 240 × 95.0 = 22,800 (lb-in).
- Totals: 2,320 lb and 203,526 lb-in, so the takeoff CG is 203,526 ÷ 2,320 = 87.73 in.
- At 2,320 lb the envelope allows 84.71–93.00 in, so the takeoff point is inside the limits.
- After burning 12 gal (72 lb at 95.0 in) the landing weight is 2,248 lb with the CG at 87.49 in — still inside. Burning fuel moves this airplane's CG forward, because the fuel sits behind the CG.
The empty weight and empty CG differ from one PA-28R-201 to the next — always use the current weight-and-balance record for the tail number you are flying. Fuel is 6 lb per US gallon (avgas).
Save your PA-28R-201 once, reuse it every flight
In TOGA EFB you register each tail number's empty weight and CG once; the loading sheet, envelope check and briefing sheet use it from then on — offline too.
