Thing is, my life is priceless to me
. Certainly worth more than a few thousand for TCAS (or FLARM, ADS-B in etc).
PPT,
No argument from me when you are spending your own money, but when there is a huge push to spend somebody else's money on somebody else's aeroplane ---- and make it mandatory, that's when proper analysis and process should kick in --- but often doesn't.
Far more than motoring "safety", aviation "safety" attracts lurid headlines, and all sorts of self-appointed experts ( eX is the unknown quantity, "spurt" is a drip under pressure) demanding "they do something", and all too often, politicians respond.
This is a huge problem in Australia, where GA has been saddled with a "WORLD'S BEST/First" (we just love being self proclaimed world first/best** something ) ADS-B mandate, far broader than the FAA or Eurocontrol ADS-B mandate --- the millions spent ( or, aircraft grounded because owners can't afford it) will not reduce risk on iota, because the traffic levels are so low, in most of the areas GA operates, that the assessed risk is not only below the ICAO Separation Assurance Standard, but is assessed as "vanishingly small", the statistical equivalent of zero, nil,zilch, naught, but it doesn't silence the "but what if ---" brigade, who are quite happy to spend every last dollar of somebody else's money.
