Hi,
Aircraft have been flying around for decades with pitot tubes which haven't iced up - how come there's been a problem with these ones?
It's not new ....
Décembre 1995 : TFU 34.13.00.005 (annexe 1). Airbus fait le constat de l’insuffisance de la
certification des sondes Pitot. Les cristaux de glace obstruent les sondes ce qui provoque une
dégradation sévère du calcul des paramètres de vol.
