This chart may be of use to some. It was knocked up many years ago for a mate who ran an I/F procedural trainer school and wanted several charts to simplify briefings. He's long out of the workforce and I have no continuing interest in copyright so I've deidentified it and you are welcome to use it if it is of any value to you.
As I recall it made life in the Link Trainer a bit easier but, as we all know, rule of thumb and watching the needles tends to be the go in the air.
I note that a few posters have been at pains to show concern about consistency of units.
That's all fine but, at the end of the day, you can use whatever units you choose just so long as you do the conversion calculations to make the equations correct ... I think that speeds in megafurlongs/fortnight or deci-lightyears/weekend would be rather cute ... but, somehow, I don't think that will take off ...
