The standard emergency phraseology for a pilot to request an arresting system to be raised is which of the following?

• A. BARRIER - BARRIER - BARRIER or EMERGENCY - EMERGENCY - EMERGENCY
• B. BARRIER - BARRIER - BARRIER or CABLE - CABLE - CABLE
• C. EMERGENCY BARRIER - EMERGENCY BARRIER - EMERGENCY BARRIER
• D. CABLE - CABLE - CABLE

Answer: (C)

Using emergency phraseology to raise the arresting system requires naming the exact piece of equipment and signaling urgency. The standard call is to say “Emergency barrier” three times. This clearly identifies the action requested (raise the barrier) and the seriousness of the situation, and the repetition helps ensure the instruction is heard and acted on promptly even in a noisy or high-workload radio environment.

Saying just “barrier” or “emergency” or referencing the cable alone could be ambiguous or fail to specify the equipment or urgency in a way controllers expect. The exact phrase “emergency barrier” repeated three times is the prescribed, unambiguous form.
