First off I'd like to express my appreciation for this fine bird, the folks at PMDG have done a great job taking FS one BIG step forward in being truly "As real as it gets."My observation is this:I use Thomas Molitor's Flight Keeper application as a log book for all of my flights. I have it set to record all events, which was fine (performance wise) up until now. It seems that the 744 logic turns on/off the pitot heat 4 times per minute (off-on-off-on.) It also tunes the nav2 radio 16 times per minute! (it switches back and forth between VOR A and VOR :( I flew a flight from Bermuda to KBNA as my second test flight and had 3000+ events occur during the flight. It would have been closer to 6000 if half the flight wasn't out of VOR range. Since each event records a substantial write to a database in FlightKeeper, this not only causes a performance hit of FS but will also make the FlightKeeper database grow at incredible rates. Questions:Not to question PMDG's talent with code, why not tune nav1 & nav2 independently when needed as opposed to the method in place?Can I turn the Pitot heat off or on instead of this automatic on/off 4 times per minute?Any suggestions are appreciated! I can, admittedly, set Flight keeper to not record the nav radio events BUT I would lose a feature that does accurate flight mapping. Thanks again to the PMDG developers and beta testers for all the hard work!John Clark

Dear John-There are specific technical reasons behind the activity you noticed, but I won't go into too much detail about them.As for Flight Keeper, let me discuss things with Thomas, to see if he can't issue an update which might accomodate.Best,

Just to keep everyone updated - Thomas is including a fix to this problem in the upcoming update, so you can all be happy about it! :-)
