bear:
Where do YOU get this stuff from? Nowhere does anything state the aircraft was DESCENDING at the start of event, except in your posts - I honestly think the BEA might have mentioned such a condition. And now you are imagining some kind of AP drop off at THS authority limit.... This is bunkum and the worst kind of dramatic imaginings, solely it seems an attempt to fit some other version of reality to the BEA framework in a twisted fashion.
