Agree with the luddites & minimalists out there
Did much of my CIR on Duchess for the last x hours. She had all the bells and whistles including RMI and HSI.
...when I got my first IFR job I was struggling to go back to all the steam driven stuff, and my first renewal (3 years after initial issue) became a fairly drawn-out affair as I really needed to be re-taught the basics.
Speed has nothing to do with it - you are just burning more money and making more noise!
Any IFR Cri-cri out there?
