Before we get too far, yes, I understand we all have things come up. Phone calls. Other stuff. Thingso which occasionally forces us to leave the app.
However, over just the past 36 hours, I’ve had at least 5 pilots set their approach auto-land, leave, disappear from RADAR, only to return right at minimums for the runway. That’s too consistent to be a coincidence.
If you do this, ATC cannot see you, and when you reappear right at the threshold, you are likely to cause an incursion.
I also had two pilots in as many days line up on the runway, leave for over 5 minutes, then return as if the command from 5 or 10 minutes ago is still valid.
When you leave the app, you disappear from RADAR. Aside from extraneous circumstances, this should not be common practice. Auto-land is not a 5 minute license to leave and scroll through FB. We need to know where you are.
