What does the flashing yellow signal represent in ATC operations?

In ATC operations, the flashing yellow signal indicates that the aircraft should proceed with caution. This means that while the aircraft is clear to continue, the pilot must be aware of potential hazards and be prepared to take appropriate action if necessary. The flashing yellow serves as a warning that the conditions may not be ideal for standard operations, signaling the need for increased vigilance.

This signaling is crucial in ensuring the safety of aircraft during critical phases such as taxiing or while awaiting further instructions from air traffic control. Understanding this signal helps pilots make informed decisions while navigating through controlled airspace or on taxiways.
