As someone who's lived on the PMDG side of the fence for awhile the FMC errors are something I haven't seen before, but as an amateur programmer, I know where they come from and that's the mass mystery of "users". You think you do something solid and good in one section, only to find out that once it's in the wild, it wasn't as solid as you hoped.
Overall, the FMC has been fine for me, until I start yanking it around, like changing approaches and STARs in flight, stacking commands before hitting "activate" and "execute" and other allowable but not normal things to do. Overall, $75 user for a clone of the Smith FMC is not what I expected nor what I received.
Here's what I got:
* A 3D cockpit that's beautiful to look at AND easy of the FPS
* A sound set worth a price of it's own. I mean, a show of hands here - who else leaves the windows open during start and taxi just to listen to engines?
* A flight model second to none - maybe the FJS 732 - but wow, what a fun plane to fly on vectors to final in crosswind!
* An FMC that can get me from point A to B in most cases out of the box, with demonstrated commitment to improvements
* An engaged dev team that is genuine in their concern and enthusiasm, not walled off in a castle on a mountain top
Not only will I continue to buy from IXEG and X-Aviation, I'm looking forward to giving them more money for even more Boeing content...
$75 = $30 for the base plane, $30 for the FMC and $15 for the sound set. When you think of it that way, isn't this a bargain?
