Stability and Control characteristics of the Early Mark Spitfires

[Crumpp]

That empty weight CG for that specific aircraft then has its specific range for foward and aft limits based on its authorized configurations. That is why the weight and balance is part of the Pilot's Handbook for that aircraft. It is required documentation and just like the Handbook, propeller logs, engine logs, and airframe logbooks follows the aircraft throughout its life.

The RAF did not have a Pilot's Handbook either, they had Pilot Operating Notes. Your post is nitpicky and irrelevant.

Sometime in the 80's by convention, everybody got on the same page as far as airworthiness documentation formats. Until then, the required information was in each nations own format but still required.

Completely wrong, neither individual CG drawings, nor weight and balance sheets were issued with the Pilot's Notes

Read the first paragraph of the very first document you posted. The specific weight and balance for that serial numbered aircraft is found in the RAF with the Aircraft handbook.

By convention, it is part of the airworthiness of that specific aircraft and part of the aircraft's maintenance documents. There will also be seperate engine, airframe, and propeller logs.
