Default Myth: 1 G barrel rolls are impossible.

Hang on, let's keep things simple:

1. If I enter a coordinated turn, I experience an increase in Gs.
2. If I enter a descent, I experience a decrease in Gs.

If I do these two things at the same time, it is possible to enter a
descending turn without any change in Gs.


Yes. Note, however, that you must _accelerate_ downward, and not
merely drift downward at a constant rate.

Just as long as I
continously feed in enough down elevator to offset the increasing Gs
from the turn, the force on the airframe and me, the pilot, will stay
at 1 G.


The additional G from the acceleration towards the center of the turn
will be constant, but the offsetting G from the descent will be
constant only if you continuously accelerate downward.

Of course, all combinations are indeed possible. But this interesting
special case of the situation exists, doesn't it, in which there is
no change in the force felt by the pilot?


Yes. It sounds a lot like a spin.


No, it doesn;t., fjukktard.
