Hi Chris,
What is the source of info for your assertion that the stall test for certification was done in Pitch Alternate Law?
I can't find a document to support it, except on page 17 of
http://lessonslearned.faa.gov/Indian...0Condition.pdf
"Several commenters note that the new VS1 usage has not been uniformly applied throughout all Part 25 subparts. As configured for operation, the A320 is prevented from stalling by the incorporation of an angle-of-attack limiting feature. This feature would then not allow demonstration of the stall speeds used for structural design. During development flight testing, Airbus deactivated the stall protection feature and demonstrated compliance with the existing rules as currently interpreted both in the clean and flaps down configurations. Therefore, the special condition was not proposed for Subparts C&D."
Besides forcing the aircraft into ALT Law, how else do you think they deactivated the stall protection feature?
