Air Asia Indonesia Lost Contact from Surabaya to Singapore

[gums]

We are moving back to the discussions several of us here had at length concerning AF447 on the Tech Log.

I disagree about going directly from "you can't stall or over-gee this plane" to "a pure stick displacement equals corresponding control surface movement". Several considerations regarding that implementation.

The whine I have is two ALTERNATE laws and a lack of training as to how the plane flies in either or both. Secondly, some things may be lost from the primary NORMAL law, but seems a few simple things could still be in play such as over-gee, as that can be derived from within the flight control computers themselves. Ditto for some of rates and pitch/roll limits. Finally, loss of air data should be no biggie, as several 'bus crews have demonstrated before and since AF447 - "standby gains" for many functions and basic "keep doing what you were doing" training.
