Slightly off the topic but;
50 years ago when the first Citation came out, it had to have 2 pilots by law because it was a jet...all 300 and something kts of it. Now we have Phenom 300's that weigh twice as much and go 100 kts faster and is certified as single pilot
Thems were the rules back last century.
Like we could not land at AF in a Citation because it was a jet even though we had a gravel kit. We were told that one after we had landed and were taxing to Rex.
I had a 30 minute argument with an ATC gentleman in Darwin who would not sign my IFR flight plan because I was flying a jet and I had planned to land on a gravel runway
The examples above were because there was no concept of what a light jet could do or were approved to do.
