Section 5. Mexican Movement and Control Messages (Transborder Flights Only)

7-5-1. GENERAL

Except as outlined in this section, handle transborder Mexican movement and control messages as described in Sections 1, 2, and 3. IFR flight plans to Mexico require the ICAO flight plan form.

7-5-2. INBOUNDS FROM MEXICO

a. Flight notification messages.

1. When received in the proper format, VFR flight notification messages are automatically acknowledged and suspended by the operational system. Deliver VFR and IFR ADCUS messages to CBP. Store IFR ADCUS messages in the history file, as appropriate.

2. Acknowledge receipt of a flight notification message as soon as practical by transmitting the letter R followed by the full ACID; e.g., R N7llVR. Deliver VFR and IFR ADCUS messages to CBP. Suspense VFR flight notification messages until arrival or closure information is received. File IFR messages. Remove IFR inbounds from Mexico from the inbound list once ADCUS message is delivered to CBP.

b. Search and Rescue. Provide search and rescue service in accordance with standard format/time increments listed in Section 3, Alerting Service, and Chapter 8, Search and Rescue (SAR) Procedures. The departure station in Mexico is responsible for initiating SAR action until an acknowledgment of the flight notification message is received.

7-5-3. OUTBOUNDS TO MEXICO

a. When customs notification service is requested for an airport­of­entry, include ADCUS, the number of persons on board, and the pilot's name in the remarks section of the flight plan.

NOTE-
Mexican customs regulations require that only international airports­of­entry may be used for first landing.

REFERENCE-
FAAO JO 7350.8, Location Identifiers.

1. If the pilot still intends to land at a destination other than an airport­of­entry, advise the pilot that the flight plan will not be used for Customs or search and rescue service in Mexico.

2. Transmit the flight notification message to the Regional Flight Dispatch Office, not the destination tie­in station.

NOTE-
If the correct addressee cannot be determined, transmit to the nearest border Regional Flight Dispatch Office.

b. When a pilot files an IFR flight plan and customs notification service is requested for an airport­of­entry, include ADCUS and the information listed in subpara 7-5-3a. Transmit to the appropriate ARTCC.

NOTE-
Mexico requires notification of an inbound aircraft before its arrival. The inclusion of ADCUS in the remarks section of an IFR flight plan or flight notification message satisfies this requirement.

c. VFR Flight Plans.

1. Upon notification of departure of VFR flights, transmit a flight notification message. When Customs notification service is requested for an airport­of­entry include ADCUS and the information listed in subpara 7-5-3a. Address messages to the ICAO addressee for the appropriate destination location.

2. If a VFR flight plan is filed with a destination other than an airport­of­entry, transmit the flight notification message to the Regional Flight Dispatch Office, not the destination tie­in station. If the correct addressee cannot be determined, transmit to the nearest border Regional Flight Dispatch Office.

NOTE-
Facilities with interphone/telephone capability may relay flight notification messages by this method.

REFERENCE-
FAAO JO 7350.8, Location Identifiers.

3. Address messages to the ICAO addressee for the appropriate destination location. Transmit the following information:

(a) Type of flight.

(b) Aircraft identification.

(c) Aircraft type.

(d) Departure point.

(e) Destination.

(f) ETA.

(g) Remarks.

EXAMPLE-
FF MMCUXMXO
DTG KSJTYFYX
VFR N1234S C182 SJT MMCU 1400 $ADCUS 4ZUCHERMANN

d. If acknowledgment is not received within 30 minutes after departure, transmit a “request acceptance” message to the destination station tie­in addressee and to the Regional Flight Dispatch Office. Manually address the message to the designated Regional Flight Dispatch Office.

REFERENCE-
FAAO JO 7350.8, Location Identifiers.

EXAMPLE-
FF MMCUXMXO MMMYXMXO
REQ ACP N1234S

e. The Regional Flight Dispatch Office involved will then normally send an acknowledgment to the departure station and assume responsibility for the flight notification message.

f. If acknowledgment/acceptance is not received within 1 hour of the departure, use interphone/telephone or other available means to deliver the message to the appropriate Regional Flight Dispatch Office. See TBL 7-5-1 for telephone numbers. For a complete address, add xmxo to the identifier.
