What is "aircraft stability" - IN VIDEO

[Crumpp]

The static stability chart you posted is not at all related to phugoid or spiral modes.

It is also not related to quantum physics. I am sure we can all think of things it has no relation too.

What it is related too is the longitudinal stability and control in an abrupt turn.

I was asking specifically about phugoid and spiral mode. Not my fault you feel a need to bring in all sorts of unrelated things to avoid an answer.

Anyway, I know now that when you said that the Hurricane, F6F and whatnotelse were hands off aircraft you didn't mean they were hands off aircraft. So we can forget about all this before it escalates into yet another 100 pages of outlandish claims without any backup by science, documents and facts.

documents and facts.

phugoid

The NACA did not test long period oscillation in any aircraft. All of the data on Spitfire and Hurricane is for short period only.

Exactly....and the conclusion in that very NACA report you use like a bible is that the short period oscilations in the Spitfire are 'satisfactorily damped in all conditions tested'.....page 18.
