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. Transborder flight plans to Mexico with oceanic routing require the ICAO flight plan while the domestic flight plan may be used for flights with route over land.

7-5-2. INBOUNDS FROM MEXICO

a. Flight notification messages.

1. M1FC/OASIS. When received in the proper format, VFR flight notification messages are automatically acknowledged and suspended. Deliver VFR and IFR ADCUS messages to Customs and Border Protection. Store IFR ADCUS messages in the M1 DD file or OASIS History file, as appropriate.

2. AISR. 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 Customs and Border Protection. Suspense VFR flight notification messages until arrival or closure information is received. File IFR messages.

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 for VFR Aircraft. 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 airport-of-entry, 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 airports-of-entry 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 airport-of-entry, 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 tie-in 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 airport-of-entry, 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 airport-of-entry 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 airport-of-entry, transmit the flight notification message to the Regional Flight Dispatch Office, not the destination tie-in 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. M1FC. For automatic addressing and formatting, use V in the flight rules of the domestic flight plan mask. For automatic addressing, use &M in the OP: field. Use the four-letter (ICAO) location identifier for the destination airport. Manually address the message to the designated Regional Flight Dispatch Office.

EXAMPLE-
M1FC
FR:V AI:N1234S AT:C182/A TS:120 DD:SAT TM:D1200 AE:65
RT:SJT..DRT..MMCU
AD:MMCU TE:0400 RM:$ADCUS 4 ZUCHERMANN
FB:0800 AA: PD: A. ZUCHERMANN
HB:SAT NB:4 CR:R/B TL: OP:&M
CP:MMCUXMXO TA:1600

M1FC will automatically address the CP: field if the 4-letter ICAO address is used in the AD: field, &M is used in the OP: field and the destination is an airport-of-entry. Only the tie-in facility will be addressed.

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

5. OASIS. For automatic addressing and formatting, select VFR in the Flight Rules text box of the Flight Plan dialog box, and enter ADCUS in Remarks.

d. If acknowledgment is not received within 30 minutes after departure, transmit a “request acceptance” message to the destination station tie-in 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-
AISR

M1FC
ORIGIN:SJT PRECEDENCE:FF TIME:1130

ADDR:MMCUXMXO MMMYXMXO
REQ ACP N1234S

NOTE-
OASIS facilities, use the Transmit General Facility Message dialog box to transmit “request acceptance” messages.

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.

g. Do not accept round-robin flight plans to Mexico.
