What does a flashing green light from the control tower indicate when taxiing with radio failure?

A flashing green light from the control tower is used to communicate critical information to pilots, especially in situations of radio failure. In the context of taxiing, a flashing green light specifically indicates that the pilot is cleared to taxi. This signal informs the pilot that they should proceed to taxi their aircraft, ensuring they can navigate away from the area safely, especially when communication capabilities are compromised.

Other options suggest actions that are not consistent with the flashing green signal. For example, a steady green light would signify clearance for takeoff, while a steady red would indicate to hold or stop. By clarifying the specific meaning of the flashing green light, it underscores the importance of understanding visual signals in aviation, especially during situations where radio communication is lost.
