Weight Calculation
The document lists the weights of various components of the Piper PA-28 Cherokee 140, including the licensed empty weight of 1,374.7 lbs, oil, pilot and front passenger, rear seat passengers, fuel (maximum of 50 gallons at 6 lbs per gallon), and baggage areas. The total loaded weight must not exceed 2,150 lbs.
Center of Gravity (CG) Calculation
Instructions for computing the center of gravity are provided, requiring the pilot to multiply each weight by its corresponding arm and sum the results to find the total moment. The total moment is then divided by the total weight to determine the CG. It is crucial to verify that the total weight and CG are within the specified envelope before flight.
Weight vs. CG Envelope
The document emphasizes the importance of ensuring that the total weight and CG fall within the 'Weight vs. CG envelope' prior to conducting any flight. This is critical for maintaining safe flight operations.
Safety notes
- Verify that the total weight and CG fall within the 'Weight vs. CG envelope' prior to conducting any flight.
