I've never operated with TCAS or CWS but understand that it can be annoying and de-sensitising as well as helpful.
Are there any statistics as to how many actual 'saves' the equipment gives when compared to false alarms or preventions of 'getting close' as opposed to 'actually hitting'?
Also, can anyone offer an opinion on whether CWS if/when fitted to GR4 and/or a Typhoon would be a Go/ No Go system? One assumes it would have to be, but at the same time that seems a bit OTT.
