.....but some controllers are just too ready to give out a tongue lashing on the radio
It's those who are my despised 'Tw@cos' - NOT all ATCOs, PPRuNe Radar! Just as I view some "Err, Golf, err, Alfa, sir, err, this, err is a Sunny Sunday err, Cheorkee, over" pilots as utter numpties!
There is an interesting brief doing the rounds from the Defence Air Safety Centre (IFS in pre-Purple days) which reminds both pilots AND military ATCOs of their responibilities and authority over flights - makes good reading!
Mind you I was brought up in my Hunter days with the edict "Don't talk to ATC unless you have to - they'll just cost you fuel!". Perhaps somewhat inappropriate in this day and age!
