What is the configuration weight for a specific modification on a Cessna 208B?

The configuration weight refers to the weight distribution of an aircraft modification and the associated center of gravity (CG) location. In the context of the Cessna 208B, selecting the correct configuration weight is crucial for ensuring the aircraft remains within weight and balance limits after modifications.

The answer indicating 24.1 lbs at +186.4 is the correct choice, as it provides a configuration weight and subsequent CG location that conforms to the aircraft's operational parameters. The weight of 24.1 lbs is understood to be the net effect of the specific modification, while the location of +186.4 indicates where the new center of gravity will be, which can affect handling characteristics, performance, and safety.

This value must be assessed against the manufacturer's specifications and operational guidelines, ensuring that the modified aircraft stays within the required limits for safe operation. Correct weight distribution is essential to maintaining stability and control during flight.

The other options, while they present some plausible configuration weights, do not align with the specific aircraft modification parameters established by the manufacturer for the Cessna 208B. Each of these alternate weights and CG locations may lie outside the acceptable range or deviate from the manufacturer's specified limits for the particular modification in question.
