Yes, they do things well, which is why I bought their new (? everything's new to me) DC-9. The Super 80 Pro is one of my all-time favorites, and to me the graphics are just clean and functional (and easy on frame rates!) Love flying around South America in my Juan Valdez livery lol

I finally completed the SBSP-SLVR flight. I'm not sure exactly what I did, but one thing was deleting the last waypoint in the route, giving me 120 miles to the 5000' hold over the airport. Even then, there was all sorts of strangeness: wandering off course, overspeed on VNAV descent, and, much to my passengers' entertainment, a barrel roll when I turned off AP. Eventually I just went to Heading Select until I could get it to "stick" to LNAV, and used VS with manual throttles to idle. In the end, while on LOC it was about 100 meters to the right of the runway, so I just cut out all the automation and flew it in myself.

While I like things to be "perfect" it is good advice to see automation as a tool that may or  may not help you complete your flight. And, up to a point, I'm willing to do that.

Some of that might be my problem, since I was goofing around showing my son the toilet and the like  :-[ So it all goes into the database between my ears, and maybe I'll sort things out.

I will say the Captain Sim 757's FMC is in-depth enough to let you create and add fixes to your flight plan, and does holds well. I have a support question in over at another forum about these issues, and haven't had a single answer yet. (Yeah, I fly other airplanes than Captain Sim sometimes. I'm not proud of it. Right now there's a cute and sophisticated European model I'm seeing quite a bit of.)

There was a discussion at AVSIM recently about support. For some unknown reason, people delight in crying about Captain Sim support. Maybe years ago, but it looks to me like the perfect system has fallen into place here. There is the KB, but knowledgeable -- I guess I can use the word fans, right? -- handle most of the support. And you guys to it so well, too. I just wish I was smart enough to help more. At yet another support forum, I don't even want to ask anything because the question might be in a 250 page manual or discoverable on the forum if you happen to hit upon the right search string. In other words, there are some people who act like support is such a bother, and delight in making you feel stupid. That doesn't go on here. So keep up the good work!
