An alternating red and green light from the control tower signifies what while taxiing?

The alternating red and green light from the control tower indicates that an aircraft is cleared to proceed, but it must exercise extreme caution. This signal is a way for ground controllers to communicate that while there is no immediate danger to moving forward on the taxiway, pilots should be very attentive and prepared to stop or take evasive action due to potential hazards or changing conditions in the operational environment.

This light signal is especially important in busy airports or in situations where the movement of aircraft needs to be closely monitored for safety. Pilots must remain vigilant and ready to respond to any instructions that may follow, given that the situation could change rapidly.

Understanding this signal is critical for the safe operation of aircraft on the ground, as awareness of one’s surroundings and potential risks is paramount in aviation safety.
