Alnot

JO 7110.65BB, Change 3, effective July 9, 2026 · Official text on faa.gov

EN ROUTE

In addition to routing to the regional office operations center for the area in which the facility is located, issue an ALNOT to all centers and Area B circuits, generally 50 miles on either side of the route of flight from the last reported position to destination. Include the original or amended flight plan, as appropriate, and the last known position of the aircraft. At the recommendation of the RCC or at your discretion, the ALNOT may be issued to cover the maximum range of the aircraft.
Note
1. An ALNOT must be issued before the RCC can begin search and rescue procedures.
2. Flight plan information on military aircraft is available at the FSS serving as a tie‐in station for the departure or destination airport. FAA tie‐in stations for airports in the continental U.S. are listed in FAA Order JO 7350.8, Location Identifiers. In the West Flight Services Area Office, tie-in stations are listed in service area publications entitled, “Flight Plan Routing and Airport Search Directory.” For flights with overseas departure points, the information is available through the destination FSS or the appropriate IFSS.
Upon receipt of an INREQ or ALNOT, check the position records to determine whether the aircraft has contacted your facility. Notify the originator of the results or status of this check within one hour of the time the alert was received. Retain the alert in an active status, and immediately notify the originator of subsequent contact, until cancellation is received.
Include pertinent information in the ALNOT that will aid the RCC and SAR Teams in conducting the SAR mission. When known, include:
1. Last known position.
2. Time.
3. Aircraft beacon code.
When information is obtained not previously contained in the ALNOT, issue an amended ALNOT to update information that will assist the SAR providers.
