CONF iture;
Unless you see something I don't, but to me both diagrams are pretty similar
You are right, they are the same. Spoilers 1 - 6 are both ground and speed brake, roll spoilers are 2 - 6, and more clearly marked in the second schematic. I would say the
Aerospatiale guys used the Airbus schematic as the basis for the one they produced.
Bearfoil;
Is your original schematic for Direct Law? (Roll Only) ?
Wasn't intended to be. But regarding the spoilers, it would appear that if 3 ADR fail, or VS1g computations fail, then there is no overspeed protection in Alternate Law, and side-stick input to spoilers in roll situation is direct and bank protections are lost.
EDIT :: As the flaps were stowed on impact, it is possible that they lifted cleanly upwards and took the spoilers out with them.
Oh yeah! I've put a red "strike-through" line through the reference to No1 spoilers not being used in the speed brake function in the
