A bit of polishing and maintenance in this small update of the simulator:
- increased chance of light category aircraft (L), mainly at North American fields where that's more common, and several traffic and plane type updates
- corrected Toronto departure headings, to allow for parallel departures at all runway configurations
- added some explanation of the meaning of several buttons (SID, DCT, etc) for absolute beginners
- bugfix to avoid a possible freeze when changing traffic mode
- bugfix that should fix a crash when the icon file is somehow not found
- V3.9.7 (2 June): bugfix for planes that sometimes didn't go around while they were too close behind eachother on the localizer. Also corrected the traffic at Tokyo.
Thanks for the feedback!
