How should the crew respond to a communication failure while taxiing?

• A. Stop the aircraft immediately and wait for rescue
• B. Use standard taxi instructions and signals, attempt to re-establish comms, and follow taxi clearance
• C. Ignore comms and proceed as planned
• D. Return to the ramp and reprogram the comms system

Answer: (B)

When radio contact is lost during taxi, follow established ground procedures to keep movements safe and predictable. First, attempt to re-establish communication on the assigned frequency (and any backup means) and verify you’ve got the correct settings. While you’re trying to regain contact, continue taxiing only in accordance with the last ATC clearance and the published taxi routes, using standard taxi instructions and signals (including any ATC light signals or hand signals you might receive). This keeps the airplane on a known path, reduces the risk of conflicts with other aircraft or ground vehicles, and preserves the ability to receive further instructions once contact is restored. Stopping abruptly or ignoring ATC advances would create hazards and disrupt ground traffic. Returning to the ramp to reprogram the radio is not a safe or appropriate action while taxiing. The proper approach is to reestablish comms and proceed under the current clearance with the help of standard signals.
