Which of the following is NOT a requirement for using a contact approach?

A contact approach is a type of visual approach that allows a pilot to navigate visually to an airport rather than relying solely on instruments. For a contact approach to be conducted, certain requirements must be met to ensure safety and compliance with regulations.

The correct answer indicates that conducting a contact approach in marginal weather is not a requirement. In fact, a contact approach is intended for conditions where the pilot has sufficient visibility to see and navigate directly to the airport, which implies that marginal weather—often characterized by limited visibility—would not be suitable. Pilots must have the airport in sight, must notify Air Traffic Control (ATC) prior to starting the approach, and must be able to navigate visually, all of which support a clear and safe operation when executing a contact approach.

Thus, while the other choices reflect crucial elements necessary for conducting a contact approach safely within established guidelines, conducting the approach in marginal weather does not align with the fundamental requirements for this type of procedure.
