Fuji...
What I meant was sometimes we expect to hear certain responses, and get a little surprised when we dont hear what we expect.
Example..
XXXX G-AVFU request FIS
G-AVFU FIS you Have
I would have expected something like
G-AVFU state positoin and type (and maybe even ask for origin and dest)
PA32 sle of man to Newtonards 2000ft mid channel G-AVFU
G-AVFU FIS you have
If I have been told I have FIS then I beleive I have FIS, I would just be puzzled why i was not asked for full details (unless I had been handed over)
