Under the condition of an empty weight of 1,271 lbs, with a pilot and copilot weighing 260 lb, a rear seat passenger 120 lb, cargo 60 lb, and fuel 37 gallons, is the CG located within the CG envelope?

To determine whether the center of gravity (CG) is located within the CG envelope, you need to calculate the total weight and the position of the CG based on the provided weights and their respective locations in relation to the aircraft's center of gravity reference points.

The total weight of the aircraft is computed by adding the empty weight, the weight of the pilot and copilot, the rear seat passenger, cargo, and the weight of the fuel. This total weight will play a key role in determining the CG position.

Next, the moment about the reference point (which is typically the datum) for each component (empty weight, pilot, copilot, passenger, cargo, and fuel) needs to be calculated. By adding these moments and then dividing by the total weight, you can find the CG's location along the aircraft's length.

If, after calculations, the CG position falls within the specified range of the aircraft's CG envelope provided in the aircraft's specifications, then the correct conclusion is that the CG is indeed within the envelope. This is crucial, as keeping the CG within the specified limits ensures safe and stable flight characteristics.

Since the determined CG is within the prescribed limits of the envelope, the correct answer is that the CG is located within the CG
