From May 2008 to March 2009, nine incidents (UAS) of icing of the Pitot probes are recorded on the A340/A330 fleet of Air France.
Coincidence?
AF 330/340
PHC logic had been modified since summer 2008 (p12-13, 16, 34)
Remember the A340 TANA flight event - august 2008 (ASR - FGNIH AF908 CDG - TNR - ALARME STALL ET PERTE DES INDICATIONS DE VITESSE SUR LES PFD).
