Where is “ground point nine” in the pilot -controller glossary. The AA guy was a tool but so was the controller.
Didn’t see it there, however the AIM paragraph 4-3-14d and 7110.65 (ATC order) paragraph 3-10-9 example shows it.
I’ve seen various phaseology issues (as a controller) over the years become major emphasis items that could be cause for displinary items. I’ve seen others that are really important that may not seem obvious to a pilot (I’ve flown part 121 as well). Finally there are guys who got burned by a particular readback/hearback error who are very particular with what they need to hear.
Bottom line almost everyone is just trying to do the job as best they can, we all occasionally take short cuts. If a pilot or controller asks for something, there is usually a good reason.
