Altitude constraints are a mess - in the short term, they are best avoided. Keep in mind the GPS code doesn't really do proper vertical navigation - it computes some data like the altitude change and climb/ descent rate for a leg, but I'm not sure if any real aircraft is driving the VNAV mode of an autopilot from it. It's definitely something I will look at, but it's tied up with some other features. At some point I want to support GPS precision approaches and then obviously all the VNAV logic will need to be properly cleaned up - right now it's been copied mostly unchanged from the original gps code. As always, user stories are good - what do you expect the behaviour to be from the route-manager? Just to track valid altitudes? For the autopilot VNAV to follow the altitude profile exactly? Something in between? This is also tied up with accurate enroute time calculations and calculating top-of-climb / top-of-descent information, it's quite a mess to unpick. ------------------------------------------------------------------------------ Come build with us!
