Very interesting G thanks.
Just in case the apparent size of CS23 puts-off people, I was pleasantly surprised when I had to do a Methods of Compliance check for a project for a single-engine sub-1000 kg aeroplane with fixed landing gear to see how much of CS23 is simply marked not applicable at that level. If you only want to do VMC or do your IMC on traditional gauges it gets even simpler. I'm not saying it's easy, it most definitely is not but it is not as bad as people think.
