AF459 sent a message to Air France at 4 h 18 so that the airline should try to contact flight
AF447. At 4 h 24, Air France asked flight AF447 by ACARS to contact DAKAR OCEANIC.
At 5 h 50, after several unsuccessful attempts to obtain information on flight AF447, Air
France contacted the SARSAT (Search and Rescue Satellite Aided Tracking) centre. The
latter had not detected any beacon transmission. Acting upon the advice of SARSAT, Air
France contacted the Cinq Mars La Pile Regional Control Centre.
At 6 h 00, the Cinq Mars La Pile Regional Control Centre called the BREST centre (CRNA
west) and asked it to contact the centres concerned with flight AF447. The BREST centre
contacted the adjacent SHANWICK centre for it to contact the SANTA MARIA centre
(Azores). The latter said that it did not have any information regarding the flight.
Between 6 h 4 and 6 h 12 the Air France OCC contacted successively the SANTA MARIA,
SHANWICK and CANARIAS (Spain) centres to find out if they had had or could have contact
with AF447, which could be in Moroccan airspace at that time. In parallel, the Air France
OCC also informed the CNOA of the impossibility of getting in touch with AF447 and asked if
there was any alternative means of detection. At the same time, the SHANWICK centre
indicated to the BREST centre that the airplane would appear to be in Moroccan airspace.

At 6 h 05 the DAKAR controller confirmed to the ATLANTICO controller that the SAL
controller still had no contact with flight AF447. At the same time, the CANARIAS centre sent
a message to the DAKAR centre requesting information about flight AF447.
At 6 h 13, the BREST centre told the Cinq Mars La Pile Regional Control Centre that,
according to an indirect source that had not been validated flight, AF447 had been in contact
with Moroccan ATC.
At 6 h 17, the BREST centre contacted the adjacent MADRID centre to find out whether
LISBOA ATC (Portugal) had information regarding the flight and if it could ask the crew to
contact its airline.
A little later, the BREST centre sent a priority message to the LISBOA, MADRID and SANTA
MARIA centres to request information regarding flight AF447 which was not in contact with
its airline’s operations control centre. It sent this message again at 6 h 24.
At 6 h 32, the BREST centre confirmed to the Cinq Mars La Pile Regional Control Centre that
SANTA MARIA had no information about the flight.
At 6 h 35, the MADRID centre told the BREST centre that the flight was at that time in
contact with CASABLANCA FIR and would enter the LISBOA FIR within a quarter of an hour.
The BREST centre transmitted this information to the Air France Operations Control Centre
and to the Cinq Mars La Pile Regional Control Centre.
At 6 h 44, after having contacted the CASABLANCA control centre, the Air France OCC
called the BREST centre and informed it that CASABLANCA did not have contact (either by
radio or radar) with the flight. The OCC specified that the CASABLANCA centre was on
contact with AF459.
At 6 h 45, the BREST centre transmitted this information to the MADRID centre.
At 6 h 51, the MADRID centre confirmed that LISBOA had no radar contact and that
CASABLANCA had neither radio nor radar contact with flight AF447. It specified that the
flight should enter LISBOA airspace within ten minutes and then establish radar contact.
At 7 h 08, the MADRID centre informed the BREST centre that LISBOA had no radio or radar
contact with AF447.
At 7 h 17, the BREST centre, which was then trying to locate flight AF447 in oceanic
airspace, directly contacted the SANTA MARIA centre. The latter indicated that the DAKAR
centre had had no contact with flight AF447 and that it was then supposed to be with the
CASABLANCA centre. The BREST centre confirmed to SANTA MARIA that the
CASABLANCA centre had no contact with flight AFR447. The SANTA MARIA centre then
sought information from the CANARIAS centre.
At 7 h 29, the Air France OCC called the BREST centre to state its concerns over AF447. It
stated that the airplane was not in contact either with Brazil or with Senegal and that the
attempts at communication using the ACARS system, SATCOM and Stockholm radio were
unsuccessful.
Note: Stockholm radio is a private operator based in Sweden that offers HF radio
communications services. Air France is a client of Stockholm radio.
At 7 h 37, BREST called SANTA MARIA again, and the latter informed it that it had not had
radar contact with AF447. SANTA MARIA added that DAKAR had coordinated AF447 with
41
SAL but that the latter had had no radio or radar contact with the flight.
At 7 h 41, the DAKAR shift supervisor informed the Dakar Rescue Control Centre that flight
