Thanks Lead, I am not blinkered and am always willing to listen.
At least your responses are measured. I will read your response again. It needs some considered time, given the effort you've made.
I certainly envy you the B707 days. My Dad used to look after you guys as an AWA LAME in the mid-sixties. I can remember sitting up in the old Darwin terminal and watching the jets taxying in, sweeping in a right turn and parking right below his workshop - he was one floor up, so we looked down on the 'monsters.' QANTAS 707s and BOAC 707s and Comets were the highlight of a young kid's week.
OK, let's kick nostalgia in to touch. You still have not justified TCAS as a mitigator if we are going to be truly 'ICAO compliant.' Lead, this was a CASA study not a 'commissioned one.'
