I find monococks attitude quite refreshing lookout is the only thing that will save you in the final instance.
I do understand the low timers who have been trained to use all the radar services and the transponder but is this leading them into a trap?. over reliance on technology is becoming a big issue in the airline business so much so that I know of an airline that is giving the new guys more time in the sim to fly visual approaches.
I don't have to dream of the days when I will aspire to all that gold braid, I already go to work dressed like an Argintinian admiral and my time flying airliners I have found a lot of places that the only sure way to avoid hitting another aircraft is to look out of the window. after all there is no radar below about 10,000ft in most of the islands in the southern Med and a lot of traffic with no transponder to show up on the TCAS..
ADS-B would be the best bit of kit fot GA but some aircraft will never be able to support it so the only system that will work under all visual conditions in all airspace is a good lookout and less time spent looking at the GPS and other such equipment.
