I was just wondering, if we could have an option of terrain for the “unable” button. Like when you press “unable” the buttons (sub-menus) could be displayed such as:
-Terrain (radio call would be something like “Unable, terrain.”).
-Send (the generic one, the radio call would simply be “Unable.”)
This is coming from a place of having been asked to turn and descend to a particular altitude and heading with a mountain near me on multiple flights, and being told to follow instructions or be ghosted after I replied “unable” and requested a climb.
Currently there’s no system as to recognise why the pilot is using the “Unable” option, which is probably why it might have developed a reputation as a button to use only if you want to be ghosted.
EDIT: I had originally suggested ‘traffic’ as an option too, but as an ATC trainer rightly pointed out, a controller vectoring an aircraft into traffic is pretty much impossible.
