When radio communications cannot be established, an aircraft in takeoff position on the runway receiving a flashing red light signal should ___.

• A. hold
• B. taxi clear of the runway
• C. continue
• D. return to the gate

Answer: (B)

When radio communication fails, pilots must rely on airport visual signals from the control tower. A flashing red light aimed at you while you’re in the takeoff position on the active runway tells you to taxi clear of the runway in use. The goal is to get off the runway quickly to avoid blocking traffic and to await further instructions in a safe area. It is not a signal to continue the takeoff, hold on the runway, or return to the gate, since its purpose is to have you exit the runway promptly.
