Recording a practice test trying to teach how to take off correctly your drone from a balcony, I leave APAS ON to demonstrate the drone behavior when you leave it on, everything went in the worse case scenario and this is the perfect example why you need to disable APAS in confinements areas.

Most of the time this test does not result in crash and instead the drone act very erratic and refuse to go out the balcony but this time was the exception resulting in a crash.
