In the hardest of all airplanes, Lee's Sentry.. I'm still watching the reliability of my CFS just as you watch the reliability of your steam gauges or an owner of BMG would be watching theirs. While CFS 4.0H is much more usable than 3.2K (Direct works on any point in the flight plan!!) its terrain is x4 more detailed and terrain decompression slows the display very noticeable. Bumpy IMC while the system is slowed by terrain decompression is down right scary.. "know thy systems!" the fully certified xbow "gyros" aren't perfect either... large acceleration (take off or landing) will result in a tilt error. (fly barring / track on low ceiling departures) The Kalman filters will level the display once acceleration has decreased. "know thy systems!" powered mags are even scarier.. one can remain in flight longer with a total failure of BMG or CFS than the lost of FADEC.. yet there are some real benefits from FADEC.. "know thy systems!" the climb rate of my parachute is less than your anti gravity disk doesn't make you safer... if your question is weather we pay more for the freedom to innovate and weed the gene pool, than having a government gun to our head to "protect" us, that is off topic for this list. CFS v4.1 will be out soon with: (from kirk) Smoother terrain decompression log file time stamp updated every second Analog Interface Unit support Skywatch support audio warnings updated with instant mute better 429 and AP command steering some display changes (MPH/Kts, waterline, trends, runways, pitch) (wsi weather isn't in this release) -- Utopian Maturity: Eternity, Liberty, Equality now Fraternity & Altruism.
