A steady red light gun signal instructs you to do what when in the air?

A steady red light gun signal while in the air specifically instructs a pilot to hold their current position. This signal is a critical part of air traffic control communications, especially when there's a need to manage traffic safely. The steady red light indicates to the pilot that they should not proceed with landing or any further maneuvers until the situation is clear, ensuring safety and orderly air traffic flow.

The other potential answers do not align with the established meanings of light signal communications. For example, returning for landing or being cleared for landing would involve different signals (like a green or flashing light), and continuing to circle may indicate a lack of immediate instructions but would not be appropriate under a steady red signal, which implies holding actions instead. This is a crucial understanding for maintaining safety in airborne operations.
