  • 10-3-1. OVERDUE AIRCRAFT/OTHER SITUATIONS

    1. Consider an aircraft to be overdue and initiate the procedures stated in this section to issue an ALNOT when neither communications nor radar contact can be established and 30 minutes have passed since:

      NOTE: The procedures in this section also apply to an aircraft referred to as “missing” or “unreported.”

      1. Its ETA over a specified or compulsory reporting point or at a clearance limit in your area.
      2. Its clearance void time.
      3. A VFR or IFR aircraft arriving at an airport not served by an air traffic control tower or flight service station fails to cancel a flight plan after receiving instructions on how to cancel.

        NOTE: If you have reason to believe that an aircraft is overdue prior to 30 minutes, take the appropriate action immediately.

    2. Consider an aircraft to be in an emergency status and initiate ALNOT procedures in this section immediately when there is an abnormal simultaneous loss of radar and communications with an IFR aircraft or VFR/SVFR aircraft receiving flight following services. This situation may be applicable to an aircraft operating in a non-radar environment and an unexpected/abnormal loss of communications occurs.
    3. The ARTCC in whose area the aircraft is reported as overdue, missing or lost will make these determinations and takes any subsequent action required.
    4. If you have reason to believe that an aircraft is overdue prior to 30 minutes, take the appropriate action immediately.
    5. The center in whose area the aircraft is first unreported or overdue will make these determinations and takes any subsequent action required.
