There are pilots around today who know how to work an aircraft, but they don't know how the aircraft works.
The whole issue of "Trimmable Horizontal Stabilisors" is a perfect example of this.
If you have managed to move the THS from where it needs to be, to somewhere else- you have entered a world of ****, and will remain there until you have recovered the situation by putting the THS back to a more appropriate position.
The THS is big. The elevators, not so much.
THS set for "big nose down?" You can pull as hard as hard as you like on the thing that moves the elevators, and you might even recover, but you'll be hauling back until that THS is in its rightful position.
THS set for "big nose up?" Houses will initially get smaller, but not for long.
That powerful THS is what gives our aircraft the ability to be safely trimmed for take off with all sorts of different loads.
Get it out of position in flight and the best you can hope for is paperwork and awkward interviews.
