Now if it also had PCAS built in, it'd be the ideal light GA traffic monitor (or everyone had ADS-B / FLARM). Would certainly be worth it for Airway IFR ops because realistically anyone in the Airways would have Mode-S.
Certainly the technology is there at reasonable cost, and FLARM does look to be the ideal choice for "us" when and IF everyone starts using it. like I said before I have no objection to paying £1000 for something that could possibly save my life - we buy liferafts for more than that but will probably never use them. Likewise with PLB's, lifejackets, parachutes, etc...so £1000 for an integrated traffic system is worth it IMHO. Of course if it can't detect the traffic then it is useless.....
