ATC Watcher:
And then you have the British that always wants yo do things differently ... for those who flew the Chipmunk remember the mixture !
I flew the Chippie, albeit in Canada but can’t remember the mixture being setup like that, though I do remember the brake setup rather well!
On the subject of standardization, I recall a working group was formed in the Eurozone approximately 12 years ago with a view to standardize Transition Altitudes/Levels throughout the Eurozone. Still waiting......
