Alpha Centauri, when you say I am incorrect about Air Services, did you mean they have already found a way to charge for LPV approaches?
It does amaze me that the rest of the developed world has gone SBAS , for years now, before ADSB, safety then efficiency. The benefits to all the various industries, particularly primary industries, have easily paid the system off several times by now But Australia knows better right!! We need Efficiency before safety.
The ADSB cost benefit was crap, I don’t know anyone who’s installation was even close to the estimates used, normally 2 to 3 times the cost, And I doubt the equipment meets the ICAO PBCS requirements, which came out last year and are now being implemented around the world. Equipment might be capable, but any current installation will need a re-assessment to confirm this, which equals $$$$.Thread drift, apologies.
