What does a steady red light in flight indicate?

The presence of a steady red light in flight indicates that the pilot must give way to other aircraft and may need to circle the area. This signal is crucial for maintaining safe separation between aircraft in the airspace and reduces the risk of collisions. The steady red light serves as an important visual cue to ensure that pilots are aware of their obligations to yield, particularly in busy airspace or during approach and landing phases.

The context of this light signal stems from standard aviation practices and helps pilots understand their role in air traffic management. While the other options represent various operational signals relevant to flight operations, they do not pertain to the steady red light's specific indication of yielding to other aircraft.
