As ATC, I encounter many instances of aircrafts taxiing and attempting take off with doors open, or airplanes approaching/landing with gears up.
Please think of a solution for the ATC. If I am both Ground and Tower, I usually hand them over to Tower and use the “Traffic Alert-Check Surroundings” to maybe help them look outside and find the issue, but it is still confusing to them, and if you are just the Ground, there are no commands to bring the open doors to their attention.
On top of that there are almost always wrong use of lights during taxi, during crossing/entering runways. That also deserves an investigation. However, I still see the open door issue the most priority. Don’t you really get annoyed witnessing it?
