Well... end of ea new story. Never heard that on the BoB era Spits.

Instead I hve read plenty of desciption of frightened young pilot force to go to batthle with under 10 hours on the type.

Never read such thing on the hurri.

You can see how precisely the pilot is able to hold a given acceleration and how smoothly the airspeed drops in the rapid turn measurements from the NACA.

It is little wonder why the Hurricane accounted for the loin's share of German fighters.

The Hurricane would not move to trim speed and stay there, it would drop a wing and dive into the ground, at an ever increasing speed. It was unstable in the spiral and phugoid modes and much worse at that than the Spitfire, which did at least a few oscillations before departing for good.
The static stability chart you posted is not at all related to phugoid or spiral modes.

Yes, a stable airplane will move to trim speed.

If it is statically stable it will move towards trim speed when disturbed.

If it is dynamically stable it will reduce the amount of speed it overshoots trim speed with every oscillation.

The oscillations will grow smaller with each cycle until they are dampened and disappear.

Just like what happens with the Spitfire's stability in Cliff's of Dover....

:confused:

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.

:rolleyes:

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.
