Under what conditions will ATC assign a contact approach?

The correct choice reflects the criteria under which Air Traffic Control (ATC) can assign a contact approach. A contact approach is a procedure that allows a pilot to proceed to an airport using visual reference rather than relying solely on instrument navigation aids. For ATC to issue a contact approach, the visibility must be at least 1 mile. This minimum visibility ensures that pilots can safely navigate visually while remaining clear of obstacles and maintaining situational awareness.

When pilots request a contact approach, they must also confirm they are able to maintain visual reference to the ground and the airport. Since visibility below 1 mile would not provide adequate conditions for safe visual navigation, it is essential that the minimum visibility of 1 mile is maintained.

The other conditions mentioned in the incorrect options provide scenarios that do not align with the operational standards for a contact approach. Conditions such as requesting a contact approach with less than 1 mile of visibility, imposing time restrictions like only allowing it during daylight hours, or stating that it can only occur when flying an Instrument Approach Procedure (IAP) do not adhere to the safety and procedural requirements set forth by aviation regulations.
