If the Aircraft Commander fails to check in within five minutes of their communications schedule, what phase is initiated?

• A. The ALERT phase shall be initiated
• B. The NORMAL phase begins
• C. The DISTRESS phase is declared
• D. The STANDBY phase is activated

Answer: (A)

Missing a scheduled check-in by five minutes triggers an immediate escalation to the ALERT phase. This phase serves as the first formal warning that the aircraft may be delayed or in trouble, prompting operations to take proactive steps: notify supervisors, attempt alternate communication, and prepare to engage search-and-rescue or additional monitoring if the situation doesn’t resolve. It isnures a timely response without assuming a full emergency is underway.

The NORMAL phase is for regular, on-schedule operations with expected check-ins. The DISTRESS phase is reserved for actual emergencies requiring urgent SAR action, not just a missed check-in. The STANDBY phase is used when awaiting further information or instructions, not as the automatic response to an overdue check-in.
