What does a steady red light gun signal mean to an airborne aircraft?

• A. Hold position on the ground
• B. Stop immediately on the runway
• C. Proceed with landing without delay
• D. Give way to other aircraft and continue circling

Answer: (D)

The main idea is how airborne aircraft respond to visual signals from a light gun used by ATC. A steady red signal to an aircraft in flight means you must give way to other aircraft and continue circling. It’s used when the runway is not available or you’re not cleared to land yet, so you hold your position in a circling pattern and await further instructions. This differs from a steady green signal, which would indicate you’re cleared to land, and from ground signals that apply to aircraft on the surface.
