Sometimes when I'n cleared to land, an aircraft is lining up at the same runway. It results in a crash or a go around. Shouldn't RC handle this?

have you downloaded the latest makerwys.exe from pete's site? after you have the latest, install it into the root of the fs directory. then next time you start rc, click the rebuild rc scenery database. that should solve your problem. if not, make a log, info at the top of the forum on how. duplicate the problem, and zip up the log file and send it to me. jd

Also, make sure Interact With AI is enabled in RC.

Thanx, that could work. Did both things. Doesn't happen a lot, so it could take some time before it might happen again.
