Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

provided a basis for the adopted measurable standards for stability & control worldwide

Great!! A basis is not an adopted standard, Capeesh??

There were several British pioneers of stability and control. In fact, Gates is the one who came up with Aerodynamic Center and Stability Margin.

It made Center of Pressure theory obsolete and was integral part of Gilruths work. Like I said earlier, Gilruth and Gates were good friends.

That does nothing to change the fact the Air Ministry had no measurable standard in place until after the war.

Your link is a meaningless and has no bearing on stability and control standards.
