Phugoid, spiral. That's all I'm talking about. I do this because you keep bringing up an A.&A.E.E. chart supposedly illustrating how poor the Spitfire's stability was, where it shows nothing but long period oscillations, i.e. phugoid and spiral mode. This chart shows nothing out of the ordinary for a high speed fighter of that day and the characteristics shown are way better than that of the Hurricane. It appears to me that up to this minute, you don't even know what you're talking about, and yet you've made 100+ posts on the issue trying to convince innocent bystanders of something that's plainly wrong.

It is really getting on my nerves, and here it is in short form, so I can simply quote me every time you bring that chart up again out of context:

The A.&A.E.E. stability records for Spitfire K.9788 show stick free, long period dynamic stability characteristics, also known as phugoid and spiral mode. The records show typical behaviour for world war 2 fighter aircraft, and the characteristics are clearly better than those of other contemporary aircraft, in particular better than the characteristics of the Hurricane, which was also tested by the A.&A.E.E. at the same time.
