That's OK - English isn't your first language. I made some quite embarrassing mistakes translating the initial French CVR transcript from Interim Report #3, so I can't be too hard on you.

The altimeter continued to unwind with the standby clearly visible from the right-hand seat, providing a secondary method of checking the aircraft's vertical trajectory.

Please don't think I'm criticising the PF, by the way - I'm just saying that those indications were there if he'd known where to look.

Of course both PNFs have no idea what are the inputs of the PF for that time.
Sometimes the simplest solutions can be obscured in a crisis situation - all they had to do was ask. The question is, why did they not think to do so?

@gleaf - The detents refer to the thrust lever settings, not the sidestick. The Airbus sidestick allows for a greater degree of travel than those generally fitted in fighters, however those comparing them to a computer joystick would really have to get their hands on one to understand that while the comparison works from a distance, they are obviously much stronger - chunkier and stiffly-sprung than that. They have to be to stand decades of constant operation.
