Spitfire I "operational limitations" January 1942

The change jumps right out at you. Go compare the operating limits page I posted from June 1940 with the page from January 1942.

You should see it plain as day. If you don't I will point it out to you later.

Why do you think they republished the Operating notes in January 1942? The Spitfire Mk I was not the latest Spitfire Mark at that time. However, 100 Octane was common by that date and required a republication of the notes.
