Not really. The trick is always to keep voice to a minimum anyway so I'd only suggest broadcasting your position and height info if you think another aircraft is going to get close enough to see you on TCAS. No doubt you can chat on UNICOM if you wish but you never know if another pilot has a critical message to transmit. It was like last night in a way as we were chatting a bit on London Centre during a quiet spell and then Steve called Mayday with engine failure. A pilot is going to get really upset if something critical happens to him and the RT is blocked by someone else talking about non essential matters. It happens though - as it does in real life - and you just learn as you get older to keep RT as brief as possible. I try to keep transmissions down to less than five seconds - amazing what you can say in that time when you sort out what you really want to say. bones -----Original Message----- From: jhb_airlines-bounce@xxxxxxxxxxxxx [mailto:jhb_airlines-bounce@xxxxxxxxxxxxx] On Behalf Of Wilding, Colin Sent: 01 September 2005 16:21 To: jhb_airlines@xxxxxxxxxxxxx Subject: [jhb_airlines] Unicom John, When flying on Unicom in absence of any ATC, what information should you broadcast, when and how often? Presumably, if TCAS and Servinfo (for example) show there are no other aircraft in the vicinity, is there any need to say anything?
