Collision Avoidance vs. "See and Avoid" for GA
I was asked for my opinion on a particular technology (PCAS - Portable/Passive Collision Avoidance System) by a colleague at work. A company (internal) pilot opinion survey had revealed that whilst people knew about the technology, none had fitted it to their aircraft. My colleague asked the question; given that this technology offers 'a decent amount of benefit for the cost' why was this the case?
I will not offer my opinion here as I intend to show this thread to my colleagues and do not want to 'set the tone' or prejudice the outcome in any way.
So, I would be extremely grateful to hear opinions on this, broadly along the lines of
1) Do you know what it is?
2) Do you have it?
3) Would you buy/fit it?
4) If so, why, if not, why not.
