  • 10-6-3. ALERTING SERVICE AND SPECIAL ASSISTANCE

    1. Provide alerting service to:
      1. All aircraft receiving ATC service;
      2. All other aircraft which have filed a flight plan or which are otherwise known to the ATC unit; and
      3. Any aircraft known or believed to be the subject of unlawful interference.
    2. When alerting service is required, the responsibility for coordinating such service must, unless otherwise established by letter of agreement, rest with the facility serving the FIR or CTA:
      1. Within which the aircraft was flying at the time of last air-ground radio contact; or
      2. Which the aircraft was about to enter if the last air-ground contact was established at or close to the boundary; or
      3. Within which the point of destination is located if the aircraft:
        1. (a) Was not equipped with suitable two-way radio communications equipment; or
        2. (b) Was not under obligation to transmit position reports.
    3. The responsible Area Control Center (ACC) must serve as the control point for:
      1. Collecting all information relevant to a state of emergency of an aircraft;
      2. Forwarding that information to the appropriate RCC; and
      3. Coordinating with other facilities concerned.
    4. The responsibility of the ACC to provide alerting service for military aircraft may be waived upon a written or recorded request from a military agency. In this case, the military request must state that the military agency assumes full responsibility for their aircraft while the aircraft are operating in the oceanic airspace.
    5. Responsibility to provide alerting service for flight operations conducted under the “due regard” or “operational” prerogative of military aircraft is assumed by the military. When “due regard” operations are scheduled to end with aircraft filed under ICAO procedures, the ACC may, if specified in a letter of agreement, assume responsibility for alerting service at proposed time filed.
    6. In the event of INCERFA, ALERFA, or DETRESFA, notify the following:
      1. When practicable, the aircraft operator.
      2. The appropriate RCC.
      3. Aeronautical stations having en route communications guard responsibilities at the point of departure, along or adjacent to the route of flight, and at the destination.
      4. ACCs having jurisdiction over the proposed route of flight from the last reported position to the destination airport.
    7. INCERFA, ALERFA, and DETRESFA mes- sages must include the following information, if available, in the order listed:
      1. INCERFA, ALERFA, or DETRESFA according to the phase of the emergency.
      2. Agency and person originating the message.
      3. Nature of the emergency.
      4. Significant flight plan information.
      5. The air traffic unit which made the last radio contact, the time, and the frequency used.
      6. The aircraft’s last position report, how it was received, and what facility received it.
      7. Color and distinctive marks of aircraft.
      8. Any action taken by reporting office.
      9. Other pertinent remarks.
    8. An INCERFA phase ends with the receipt of any information or position report on the aircraft. Cancel the INCERFA by a message addressed to the same stations as the INCERFA message.
      1. An ALERFA ends when:
        1. (a) Evidence exists that would ease apprehension about the safety of the aircraft and its occupants; or
        2. (b) The concerned aircraft lands. Cancel the ALERFA message by a message addressed to the same stations as the ALERFA message.
      2. A DETRESFA ends when the:
        1. (a) Aircraft successfully lands; or
        2. (b) RCC advises of a successful rescue; or
        3. (c) RCC advises of termination of SAR activities. Cancel the DETRESFA by a message addressed to the same stations as the DETRESFA message.
    9. A separate chronological record should be kept on each ALERFA and DETRESFA together with a chart which displays the projected route of the aircraft, position reports received, route of interceptor aircraft, and other pertinent information.
