This table provides essential information for weight and balance calculations for the Piper Cherokee models 140, 180, and 235. Some key points to remember:
- The Cherokee 235 has a significantly higher gross weight and fuel capacity compared to the 140 and 180 models46.
- The useful load varies between models, with the Cherokee 140 having the highest at 1239 lbs.
- All models have a maximum baggage weight of 200 lbs46.
- The arm (center of gravity location) increases slightly from the 140 to the 235 model.
- When calculating weight and balance, remember to consider the specific arm for each load (passengers, fuel, baggage)23.
- Some Cherokee 180 models may have a slightly higher gross weight of 2450 lbs, so always check your specific aircraft’s documentation3.
- The seat positions can affect the weight and balance. For example, moving the right front seat to the aftmost position (9th notch) can help balance the aircraft when it’s loaded heavily in the front5.
Always use the specific weight and balance data for your aircraft, as there may be variations due to equipment installed or modifications. As the pilot in command, it’s crucial to ensure your aircraft is within its weight and balance limits before each flight.
