Crash A321 AirBlue 28/7/2010 - Ma ci sono comandanti così ?

[sigmet]

Sembra che il F/O fosse ben cosciente della situazione e nonostante tutto ha avvisato il Cpt in diverse occasioni:

this Sir higher ground has reached, Sir there is a terrain ahead, Sir turn left."

The heading bug was rotated left, however, the aircraft did NOT turn. Two "TERRAIN AHEAD" aural caution messages sounded.



"Sir, turn left, pull up Sir! Sir, pull up!"


35 seconds before impact the throttle levers were brought into the MCT detent and the autothrust was disengaged, the selected altitude changed to 3700 feet, the aircraft still turned right. 6 seconds after the throttles were placed into the MCT detent they were moved to the CLB detent and autothrust was engaged in CLIMB mode, the selected altitude was reduced to 3100 feet.


6 seconds prior to impact the first officer exclaimed "TERRAIN, SIR",

"Sir, we are going down! Sir, we are going down!"

Al di la' della scarsa crew coordination mi sembra che anche in questo incidente l'interazione tra la guidance e il pilota mostri qualche lacuna:
The first officer again pointed out: "Sir terrain ahead is coming", the captain responded "we are turning left". The heading bug was rotated left, however, the aircraft did NOT turn. Two "TERRAIN AHEAD" aural caution messages sounded.

In an attempt to turn the aircraft to the left the captain again rotated the heading bug, however, he did not pull the heading rotary knob so that the NAV mode did not disengage and the heading track mode did not activate. The heading bug reached a selected heading of 086 degrees.
12 seconds later, 40 seconds before impact, the autopilot mode finally changed from nav to selected heading mode, the aircraft was tracking 307 degrees at that point, the selected heading mode activated. As the shortest turn towards the selected heading 086 was to the right, the aircraft turned RIGHT towards the Margalla Hills.
Il fatto poi di costruire il sottovento sull'FMS e (tra l'altro a 3/5 NM) e' un chiaro segno di complacency verso l'automatismo.Qualcosa mi lascia pensare che il Cpt gia' minato nelle sue capacita' cognitive si sia incasinato con i bottoni e non abbia guardato fuori.
