As you know stick free Airbus trims for 1g and not for speed. AoA or speed data is not needed for that.The AD is for frozen AoA and not for frozen Pitot. These have different implications. In frozen Pitot case one ADR is kept for stall warning which comes from AoA probe and not for pressure data. However in frozen AoA case stall warning will also be false. This AD is not very comprehensive and doesn't cover frozen Pitot and can mislead the pilot if Pitots are also blocked. A320s which have MOI153528/P12909 the FPV is modified to calculate FPA from hybrid GPIRS(mixed IRS and GPS position). So you can use it in this case. But without this MOD bird can only be used provided Pitot/static is not blocked.
