Section 3. Information Requests (INREQs)

1. INREQ

If the reply to the QALQ is negative or the aircraft has not been located within 30 minutes after it becomes overdue, whichever occurs first:

1. The destination tie-in facility/sector must transmit a numbered INREQ message addressed to:

1. Flight plan originator (if other than AISR).
2. En route FSS as applicable.
3. KSARYCYX (includes RCC and AISR).
4. En route ARTCCs as applicable.
5. BASOPS if destination or departure tie-in facility.
6. Other addresses the specialist deems beneficial to the search.

1. Include the flight plan and any other pertinent information in the INREQ message which could assist in search activities. Retrieve data from the history files, format the message, and transmit. Provide the aircraft's last known position as the final item of the message. The message text must begin with the contraction “INREQ,” followed by the aircraft identification.

1. If the departure airport, route of flight, destination airport or alternate airports are within 50 miles of the Great Lakes, notify Cleveland RCC via recorded telecommunications line
2. If the flight is within the Honolulu sector, notify Honolulu SARCC via recorded telecommunications line.
3. RCC does not have transmit capability. Acknowledgement is not required for messages to RCC.
4. If additional information is received in INREQ reply messages, transmit the information, as necessary, to all original addressees.

1. ACTION UPON RECEIPT OF INREQ

Stations receiving an INREQ must take the following action:

1. Search facility records for information regarding the aircraft. Expand the communications search to include all flight plan area airports along the proposed route of flight that could accommodate the aircraft. Notify appropriate ATC facilities. Reply to the INREQ within 1 hour of receipt with flight plan and other pertinent information. If unable to complete the communications search within 1 hour, forward a status report followed by a final report when the search is complete.

1. If the INREQ indicates that the departure airport, route of flight, destination airport or alternate airports are within 50 miles of the Great Lakes, notify Cleveland RCC via recorded telecommunications line.
2. For facilities that have any portion of their incoming calls and/or Service B diverted to another facility, notify that facility of the INREQ. The facility receiving diverted calls or Service B traffic must check their records and advise of any information or contact with the aircraft.

1. CANCELLATION OF INREQ

The INREQ originator must transmit a cancellation message containing the location of the aircraft to all INREQ addressees if the aircraft is located. Notify associated ATC facilities.
