A couple of suggestions for the landing status display used in ATC that shows incoming flight plans. I don’t think any of these is a significant coding.
a) Direction would be useful. If there is no approach, as there often isn’t, a bearing would be useful with the distance for planning ahead. Not quite sure how realistic this is, though. Can be calculated with Atan2 from position of aircraft and airport.
b) The status display doesn’t auto refresh when you switch to it. This may be deliberate for interface reasons, or because it’s a heavy load on the server perhaps, but consider updating the ATC state and incoming display when you switch to it from another view.
