ISIS is not especially larger than the standard standby indicator, and the standard standby indicator is not more 'unreadable' than the ISIS.

Pretty rare, but I can still remember flying under MEL an entire week or so without it due to a defective trim tank isolation valve.

Never the MAC could have been to 38% after only 3 hours something in the flight, not with the initial very much forward 23% CG at takeoff time. My own estimate would have put it around 32% at the time of the event, but the BEA now mentions 29% ...

If now to have to trim an airplane overloads a pilot, so, something is very wrong with the airbus philosophy. How will cope a pilot the day he has to do it when the system pushes him to lose that practice. Let the pilot trim, it is just more pleasure and SA in the mean time.

Something big is missing in the story : I can't believe 3 guys would have maintained NU inputs for 3 minutes with 3 A/H showing blue blue blue and 3 altimeters going down like crazy. BTW, what did say the captain ? Nothing ... ?
BEA, just publish the data, and if we don't deserve them, the victim's families surely do. Why can't they get them ... ?
