This page represents the FAA TCDS 2A13 PA-28R-180 normal-category configuration. Enter the current basic empty weight and arm from the certified weight and balance record for the individual aircraft.
Maximum weight: 2,500 lbs. Usable fuel: 48 US gal. Fuel arm: 95 in.
| Specification | Value |
|---|---|
| Maximum weight | 2,500 lbs |
| Forward CG at 1,925 lbs or less | 81 in |
| Forward CG at maximum weight | 91 in |
| Aft CG limit | 95.9 in |
| Usable fuel | 48 US gal |
| Fuel arm | 95 in |
| Certification source | FAA Type Certificate Data Sheet 2A13 and applicable Piper POH/AFM |
| Aircraft weight | Forward CG limit | Aft CG limit |
|---|---|---|
| 1,925 lbs or less | 81 in | 95.9 in |
| 2,500 lbs | 91 in | 95.9 in |
The calculator uses straight-line interpolation between published forward-CG breakpoints.
| Station | Arm | Limit |
|---|---|---|
| Pilot and front passenger | 85.5 in | |
| Rear passengers | 118.1 in | |
| Baggage | 142.8 in | 200 lbs |
| Fuel | 95 in | 48 US gal usable |
The calculator uses 48 US gallons usable at an arm of 95 inches. At 6 lb per US gallon, full usable fuel weighs 288 lbs.
WBcalc intentionally does not prefill a generic empty weight or empty CG. Use the current certified values for the individual airplane.
The Piper PA-28R-180 Arrow calculator on this page is model-specific. It uses the loading limits stored for this aircraft configuration rather than applying a generic set of limits to the whole Piper family.
The maximum takeoff weight represented by this calculator is 2,500 lb. Total loaded weight must be checked separately from center of gravity because an aircraft can be below maximum weight and still be outside its approved CG envelope.
For the configuration represented here, the forward CG limit is 81 inches at 1,925 lb and reaches 91 inches at 2,500 lb. The aft CG data represented by the calculator runs from 95.9 inches at 1,925 lb to 95.9 inches at 2,500 lb. Where a limit changes between published weight points, WBcalc uses straight-line interpolation between the stored breakpoints.
A calculated loading must satisfy both the forward and aft CG limits. Being below maximum aircraft weight does not by itself mean that the loading is acceptable.
This calculator represents up to 48 US gallons of usable fuel at a fuel arm of 95 inches. The calculation uses a fuel weight of 6 lb per US gallon. Fuel contributes both weight and moment, so changing fuel quantity can change both total aircraft weight and loaded CG.
Passenger, baggage and other loads must be applied at the correct loading stations. The calculator uses the following station data for the represented configuration:
Pilot and front passenger is represented at an arm of 85.5 inches.
Rear passengers is represented at an arm of 118.1 inches.
Baggage is represented at an arm of 142.8 inches with a maximum load of 200 lb.
Start with the current basic empty weight and basic empty arm from the weight and balance record for the individual aircraft. Do not assume that the empty weight of another aircraft of the same model is correct for the airplane being loaded.
Next enter the actual occupants, baggage and usable fuel for the planned flight. If the calculator provides an adjustable arm field, enter the applicable loading position from the approved aircraft loading information. Then calculate the total loaded weight and center of gravity and compare the result with the limits shown by WBcalc.
Use the current certified basic empty weight and empty CG or arm for the individual airplane. Empty-weight data can change when avionics, interior equipment, paint, repairs, optional equipment or approved modifications are added or removed. A generic model value is therefore not a substitute for the current aircraft weight and balance record.
The datum represented by this calculator is: Piper PA-28 datum; see applicable POH/AFM. Arms and center-of-gravity positions are measured relative to the applicable aircraft datum.
Other Piper aircraft calculators available on WBcalc include Piper PA-28-151 Cherokee Warrior, Piper PA-28-161 Warrior II, Piper PA-28-181 Archer II, Piper PA-28-181 Archer III, Piper PA-28R-200 Arrow II, Piper PA-28R-201 Arrow III, Piper PA-28RT-201 Arrow IV. Use the exact model and configuration that applies to the aircraft being loaded.
The calculator on this page represents a maximum takeoff weight of 2,500 lb. Confirm that this weight applies to the serial number, configuration and approved modifications of the individual aircraft.
The configuration represented by this page uses up to 48 US gallons of usable fuel. The applicable fuel system should always be verified against the aircraft POH or AFM and installed configuration.
Because basic empty weight and empty arm belong to the individual aircraft. WBcalc avoids presenting a generic value as though it were the current certified value for every Piper PA-28R-180 Arrow.
Yes. Maximum weight and center of gravity are separate limitations. A loading can remain below maximum weight while the CG is too far forward or too far aft.
No. WBcalc is a planning and calculation aid. The approved POH or AFM, current aircraft weight and balance record, equipment list, supplements and other applicable approved documents remain authoritative.
The aircraft data stored on this page identifies the source as FAA Type Certificate Data Sheet 2A13 and applicable Piper POH/AFM. Always verify that the represented configuration applies to the individual aircraft, including serial-number applicability, supplements and approved modifications.
Primary source: FAA Type Certificate Data Sheet 2A13 and applicable Piper POH/AFM. TCDS 2A13 specifies 2,500 lb maximum weight, seats at +85.5/+118.1, 200 lb baggage at +142.8 and 50 gal total fuel at +95. Contemporary PA-28/PA-28R operating data identify 48 gal as usable fuel.
Serial-number differences, approved modifications, STCs, floats, supplements or equipment changes can alter applicable data. Confirm the page against the documents for the individual aircraft before flight.
