Hi Chris - I'm struggling a little to understand what you mean. I'm not referencing anything too complicated, just the statement regarding the Abnormal Law, below.

Now I know the BEA has stated that the airplane never reverted to "Abnormal Law" as a result of the high AoA but they dont' explain why and that is really confusing. Another piece missing, which will show up sooner or later.

Here's my reference - not sure it answers your question:

Abnormal attitude law
This law from the FCPCs is engaged when certain aircraft parameters exceed predetermined values.

The laws in place would be:
- in roll: - yaw alternate law
- in pitch: - a modified Nz law, without autotrim.

After aircraft recovery, and until the aircraft is on the ground, the available laws are:
- in roll: - yaw alternate law, (in this case Alternate Law 2)
- in pitch: - Nz law, (with recovered autotrim).

"In haste", as you say Chris!...gotta do some work. Hor's de combat so to speak, over the next while.
