same stability and control standards for a 150 mph biplane fighter as for a 450 mph monoplane

NzTtyphoon,

The basis for all modern stability and control was developed during World War II. Outside of Germany, the NACA was the worlds leading organization for Stability and Control.

Fredrick Lanchester did some pioneering work and is considered the foundation for stability and control. He correctly theorized on vortex theory of lift with gliders secured by wire, conceptulized aircraft oscillatory motion which he called "fleeing motion" instead of phugoid. He published several works and even spoke with the Wright Brothers in 1908.

None of this was put into any mathmatical definition. Fredrick Lanchester was not able to put his ideas into any useful mathmatical form.

I have been waiting for you to realize this since you brought it up. I have ignored most of what you write because it is obvious you argue based off emotional attachment and do not understand much of what you claim. It is another red herring like arguing for pages about a non-dimensional proportion.
