This turned out to be two subtle bugs in creating the atmosphere’s vertical temperature profile, where it was possible to get a sudden change instead of a smooth gradient. People flying airliners found that their altitude was suddenly changing during cruise, sometimes by hundreds of feet, making their autopilot want to take a bit of a lie down in a dark room. They still called final and landed correctly, this was just a missing radio message. Take two for the “AI not calling downwind” bug.ĪI may not always have called downwind.Allow editing of ATC flight info if required information is missing, even if a flight is under way.Since this change I finally got a log from a bug report that let me nail the main cause, and a final (?) fix should hopefully be included in 12.07. This is a long-standing bug with repeated altitude correction calls from the controller, when you were already at the right altitude. Modify altitude monitoring to try and remove inappropriate warnings.Note that you can also request pushback by radio, from ground or tower. These two should make the text messages and buttons in the pushback dialog clearer and more consistent with the current state. Merge branch ‘fix_XPD-13783_Pushback_Dialog’.Merge branch ‘fix_XPD-13780_Pushback_Messages’.This simply clogged up the airwaves for the first minute or two of your session. Fix unwanted transmission possible during spawn of AI on arrival.AI had a stupid max speed under “AI flies” at key points on the ground which was never reset.Fix incorrect voice phrase for requested altitude change.Many of these changes, especially the ones starting with “Merge branch”, would be made up of many changes themselves and could cover days to weeks of work others might be a change to a single letter. This is a very high-level list of the changes that went into 12.06, now with added explanations! I’ve removed about half of it because they were maintenance, corrections to previous changes and other non-visible things, and edited some of the rest to protect the idiot innocent. More on that later.įirst though, a quick peek behind the curtain. Normal progress has been slowed, however, by time spent on adding one huge new feature. Normal work on bugs and small improvements has been going on as usual, and 12.06 contained quite a backlog of these which I’ll go into more detail about below. You’d be forgiven for thinking that the answer to the first is “not much”, simply because there’s been very little visible in the release notes for ATC, but that’s definitely not the case. Jim Keir here – today I’m going to talk about what’s been going on with ATC for the last six months or so, and what’s planned for the near future.
