Radio's
Ok...Ideal thread to ask this one.
I was controlling an A139 today which went "off my frequency" for over 5minutes. I tried the aircraft many times and also another company aircraft tried....tried the radio fail procedure....nothing.
After a while the pilot said something to me......and said that the radio had gone off. I know we have a problem with the aircraft not being able to get us on test (as the S76 can do) as the digital radios dont let them....
But....where and how can the radios be turned off. We got into a big ops room chat in ATC and wonder if a radio switch maybe easily touched and nobody notices?????
Be good to hear any ideas on this.....my first instruction when the pilot came back was "avoiding action ...turn left....."
