As in, trimming for stable climb rate? Some version of 'cruise' climb? As energy depletes, the THS increases Pitch Up to maintain climb? Something in this climb suggests a maneuver that the pilot felt was OK? I am lost how "trim" has any place in what one would think an emergency maneuver? The BEA say, "FROM 2:10:05, ".... They leave out a sequence of pilot displays. What information was the PF operating on to continue this climb draining energy merely to gain altitude? Was he trying to dump overspeed? Or was this THS movement unknown to him, he believing he had plenty of energy, and felt his AoA was reasonable? Had he thought he was merely initiating a "Little bit to the left" turn? Adding just a bit of NU that the THS decided to chase? When did he Know he was without A/THR, and auto trim wouldn't mess him up? It was eleven seconds after the a/p that both of them made note of the sitch.
Halp!
