109 elevator trim

[VO101_Tom]

To the trimm topic. I know, it's G, but the trimm mechanics is the same:
(For those who doubt that the trim could be used at any time... )


"Sarantola recalled that the MT was a very stable plane, but not the most maneuverable. The stick forces were quite large and elevator trim was used quite frequently while maneuvering.
MT was easy to fly and overall a safe plane. Flying and landing was easy."

Even more interesting is the fact that they tried different positions of the trimming. With the wrong trimset - the one for cruising at high altitude it was not possible to pull out of the dive just by using the stick. They needed to use the trimwheel to recover the plane from the dive. This happened in such violent manner that the testpilot had to push the stick foreward to be not blacked out...
If the trim was set to +1.15° it was possible to recover without using the trimwheel - both flightpaths, with and without the trimwheel, are very similar. So even with the concrete stick the limitating factor seems to be the pilot.
Also interesting in the dive the canopy iced, also the mechanism of the trim, so it was not possible to set it smooth, but in \"jumps\", but it was still adjustable...

Clarification of the escape dive: "It didn't stay (vertical) otherwise, it had to be kept with the stabilizer. I trimmed it so the plane was certainly nose down. Once I felt it didn't burn anymore and there was no black smoke in the mirror, then I began to straighten it up, and it wouldn't obey. The stick was so stiff it was useless. So a nudge at a time, (then straightening off with trims).
Then the wings came alive with the flutter effect, I was afraid it's coming apart and shut the throttle. Only then I began to level out. To a thousand meters. It was a long time - and the hard pull blacked me out."
