If a gyroplane has a basic weight of 1,315 pounds, what can be inferred regarding its CG envelope?

To understand the situation regarding the center of gravity (CG) envelope in relation to the gyroplane's basic weight of 1,315 pounds, it is essential to consider what the CG envelope represents. The CG envelope is the range within which the center of gravity must be located for safe and stable flight.

Choosing that the gyroplane is outside the CG envelope, but the maximum gross weight is not exceeded, suggests that while the weight itself is acceptable, its distribution is likely not suitable for flight stability. This can occur if the weight is distributed in a way that shifts the CG too far forward or backward outside the acceptable limits defined by the manufacturer.

However, without additional information about the location of the CG in relation to the allowable limits and the specific weights associated with the gyroplane's design, it cannot be definitively concluded whether the aircraft is within the specified CG envelope or not. This is why one would select this answer as it emphasizes the importance of knowing both the CG location and weight distribution to make an informed determination.

Determining whether the aircraft meets the criteria for safe flight based on its CG involves additional specifications from the manufacturer's limits, which are not provided here. Thus, the knowledge surrounding acceptable limits and constraints reinforces the choice.
