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....."

Akitomo: the picture with
looks like the Air con module...

Can you explain what do you mean with this:
About the radios... recently an aircraft lost the COM1,NAV1 etc. due a network card failure, it was necessary just to reset the circuit breaker, but to lost com1&2 in the same flight...

AW139 Radios
The Digital radios on the 139 can be put into test or Squelch off.
Also, what catches a lot of pilots out is:
If either comm 1/2 recieve channel is off, if it is then reseleced by pressing the transmit select button the radio receive channel is then selected on, but if however the pilot chooses to speak on the other 'Box' and presses the transmit select button for ther other comm the previous channel is then turned back off........ it will only stay selected on if it was previously selected on prior to the transmit channel being selected........
does this make sense?

The right pic has been uploaded. Thanks for pointing out!
Griffo - re suck it up - I saw the aircraft at Valley last week and yes it does look good but the only reason it has been chosen is because AW got the Algerian contract (thanks to the MoD) and the 139 is cheap and better than the 412 - not because it 'sets the standard' for modern SAR.
If it set the standard it would have an aux hover trim capability for night wet winching and a cabin that you could stand up in. If a land ambulance turned up with a roof so low the paramedics had to work on their knees, there would be outrage but no one listens to the rearcrew when considering what is and isn't a good SAR helicopter and they are the ones who get to do all the really nasty and dangerous stuff in SAR.
I bet manouevering a 20 stone patient in a stretcher is a laugh a minute in the back of a 139 - how long will it take before all the rearcrew are off sick with bad knees and bad backs? Remember all the H&S training about how to lift with your legs and not your back? - how is that going to work when you can't stand up?
The 139 will be OK in the training role and in some theatres where a true and full SAR capability isn't needed/wanted/affordable but it is not, and never will be the standard for light/medium twin SAR. It's cheap.........that is the overriding argument for choosing it.

That with radios reminds me on our test flight, no one on board was able to
properly switch intercom between passenger area and crew, ANR on
loudspeakers to earphones and back, also comm between pilots was
questionable, things finally finish up with finger signs

Mozzy: not a big problem if you look at the lights when selecting radios...
Akitomo: is the 139 just for news gathering???
