Dan, 'dangerous', a bit strong; don't want to frighten the poor dears. Challenging, yes, for the reasons outlined.
Challenges are there to be met, anticipated, and managed; beware of surprise -
"a landing is an approach without a GA", plan for workload, and simplify procedures (including Nav and ATC - see ASAGA report).
Centaurus, yes illusions are a threat, but more often an illusion can be managed having been previously experienced - basic training?
The 757 and similar aircraft have strong nose up pitching moments with GA power, thus reduce power and manage the pitch control. Unfortunately many pilots have been influenced or even trained by the mantra to fly the aircraft in trim; in the extreme to fly the aircraft with trim, and thus are reluctant to use input large control deflections or experience high control forces.
A significant issue in this event, and others, is expecting the autopilot to take over with the aircraft out of trim. Autopilots have no brain - no situation awareness, limited anticipatory ability, and restricted application of control forced and trim rate (safety features).
If a pilot handed over the aircraft to me out of trim, there was a severe cuffing around the ears; perhaps autopilots should have a similar feature, or at least pilots be aware of the limitations of handing over control to a dumb system.
