Alright, lets talk about stalls.

How about an elevator trim stall. Airplane pitches up until the critical AOA is reached and stalls. When it stalls, the nose drops, AOA is reduced, airspeed is gained. But, if the trim is left where it is, it will eventually pitch up to the critical AOA again, stall, gain airspeed and go on continuously like this.

So what kind of static and dynamic stability would this be an example of?
Also, are we talking lateral, longitudinal, or vertical stability?

How about a cross controlled stall. How would we define the stability in the yaw axis after the stall occurs?

What theories of aircraft design promote stability so that we can perform stalls safely? Wing dihedral, ventral strakes, etc?

Everything in aviation is related.
