L'article cite plusieurs précédents, avec notamment un cas qui concernerait un C français:IAF flight records examined by the CoI have revealed at least four such incidents in the past. In each of these, a flying Mirage 2000 has, suddenly and without command from the pilot, jerked its nose towards the ground. Then, as spontaneously, the nose was jerked upwards. Each time, the aircraft has continued this up-and-down jerking — termed “pitch oscillations” — for several seconds before resuming normal flight.
Similarly, in 1999, Mirage 2000, aircraft number C98, “experienced momentary pitch oscillations… (for) a few seconds at 10,500 feet altitude, exerting a force of 11g on the aircraft and pilots. Exerted over a few more seconds, 11g force would cause most pilots to black out.
Au total, ça ferait quatre cas rapportés en vol, dont trois indiens (dont un planté), + une anomalie détectée au sol (encore sur un indien).Dassault, which supplies the flight computer, offered the explanation that the aircrafts’ “pitch rate gyrometers” — sensors that tell the flight computer the aircraft’s attitude – were not securely fitted. But neither the IAF, nor HAL, is convinced, since the Mirage 2000s behaved perfectly for the rest of the flight when the incidents occurred.
75% des cas qui concernent des Mirages indiens, ça me semble un peu trop statistiquement déséquilibré pour qu'il s'agisse d'un dysfonctionnement des CDVE indépendant de la maintenance, mais je parle peut-être un peu trop vite.
Par contre, de retour au hangar, ça a du miauler.
