Moving to high thrust is felt by the gravity vector shifting off your butt a little toward your back. There's another thing that has this effect: pitching up. The two can be really hard to distinguish.
(In fact, this idea of gravity-relative-to-butt is very strong in people and when that fails to be a useful model is often when we see accidents happen.)

- kqr 4y agoOn the same theme, inverted flight feels like a rapid change of pitch downwards (both accelerate you kind of toward your head), so the natural response is to "pitch back up" and get the acceleration back under your butt (which of course inverted means you actually start diving for the ground).
- HPsquared 4y agoNot sure about that, if there is no additional thrust the aircraft will be decelerating because it's running "uphill", pulling the gravity vector forward. It'll be balanced, so you don't "feel" acceleration or deceleration. It's the same in a car, if you are coasting in neutral and encounter a hill, even though the car will be slowing down there is no "perceptible" longitudinal acceleration because it's caused by gravity (equally acting on the car and the occupant), just like in space or one of those zero-G flights. There would be an increase in drag when pitching up, that would also cause deceleration.
