Yep, agree on transponder to STBY unless entering or departing the GAAP.
WRT Capstone. That is a bit of a bunfight over not so much standards of equipment but comparable standards from ADS-B to radar. Not sure if it was a union or FAA or combined but ADS-B was pulled as a separation device in ATC. It was still available but ATC could not provide a separation service using ADS-B alone. Strange stuff! Over here our upper airspace ADS-B ATC provides the exact same separation standard with ADS-B as radar.
Haven't heard any more about Alaska and ADS-B. Was in contact with the local ATCOs but they must now refer me back to the FAA over the subject. So, if that is still going on I could well imagine the locals would be a little reticent to take up the loan offers until the FAA sorts itself out.
As for over here. The jury is still out on the subsidy for GA VFR, also includes RAA. Everything I have seen points to a basic ADS-B 1090ES transponder including a TSO145/146a GPS. The GPS may be included within the transponder for VFR. IFR get a few more goodies so AirServices can also look at shutting down certain navaids.
In this case though. NO electronic serveillance would have avoided the accident. Transponder, FLARM or ADS-B. Unless there is a re-write of the rules that mandate ADS-B ON AND a real time feed inside the control tower cab with allowances and licences for the tower staff to use the feed as a separation device if so needed. Especially if a built in alarm was to sound alerting tower staff to a close proximty within the circuit area with enough seconds to contact aircraft and give instructions to avoid each other. EN has a radar feed from ML CENTRE but they aren't allowed to use it as a separation device. Only to aid them in locating you visually. If there are any ATC on the thread I hope they can set me straight wrt radar use in the tower. EDIT- just to add, it has saved me heaps of times to get the call from the tower to ensure my parrot was squawking. Me started flying before transponders were common. Still have to remember Lights-ON Camera-Transponder to Mode C, Action-Cleared for Takeoff, Power and T & Ps all green.
