A purely hypothetical view, as most here know, I am not a licensed pilot .
The "average -bimbler " is an infrequent flyer (Benchmark = Commercial pilot or , say, 3 flights flights a month ) Their reactions and skill-level will be at less than optimum. As a bimbler of low hours and frequency, they are unlikely to be venturing to foreign climes, will probably avoid both controlled airspace and long UK journeys into unfamiliar territory.
I'd suggest , therefore, that PAW would give them the security-blanket and workload reduction that will aid their safety, at a very modest, affordable cost.
Of course, the device has it's limitations, not least of which is the fact it costs 1/3 the price of it's nearest competitor.
A cunning work-round to the FLARM protected- market strategy appears to be working. Given the fact that FLARM was specifically tailored to a niche market (gliding) and it's unique needs of frequent close-proximity engagement in lift, and the length of time it's been on the market, It's hardly surprising that it has such large numbers out there.
PAW is a product aimed at a different sector, with a different ethos and a different business model. It seems to me, an outsider, that here's a group of people who said to themselves,-
" Lots of low- budget flyers have a need for conspicuity at low cost, It doesn't need the huge expense of Certification. We can build something round the amazing" Raspberry Pi ", cheap as chips and with lots of bonus features that will make a flashing strobe look like a poor joke.
As I said, I watched hands go up. There were a contingent of Glider pilots there, some had both FLARM and PAW.
It's not rocket- science to look at how long both devices have been available and then observe the rapid uptake of PAW, It's development has been amazingly fast and it's moved from a "hobby-shed lashup" to a portable , practical safety- aid that's totally suited to the market it serves.
It is being adopted abroad and no doubtwill find widespread acceptance there, Just think, English was a foreign language to the rest of the world, for centuries...yet now , after a couple of hundred years, it's accepted as the international universal standard.
I wonder how many "knockers" also said the same about Sky Demon when it originally appeared. market acceptance takes time.
Really, people, you are very lucky that such competent, clever and dedicated people are willing to use their skills to fill the needs of such a tiny market.
DISCLAIMER! I have never knowingly met anyone involved directly with the production or development of any of this equipment. I try to speak as an objective independent observer.
