OK....in my opinion this is what should be implimented.
ADSB upper level as is moving ahead. Definite benefits enroute.
ADSB Lower level;
- original radio sites etc asa per original proposal.
- all GA from Ultralights to charter to have a minimum combination ADSB/Mode C transponder (ADSB OUT ONLY). Supplied FOC.
- ADSB in is a nice option for RPT or anyone wanting to spend the $$$ to fit it.
The benefits of this is ATC have vastly more coverage. Everyone is in the system, allowing IFR to have better traffic seperation / information. All the non transponder fitted a/c then have a transponder, thus providing TCAS alerts for RPT (or anyone fitted with TCAS) & protection that they do not have at so many regional aerodromes. Examples are Hervey Bay or Ballina.....and dozens more! When a B737/A320 cleans up a Piper Cub and 180 people die, these words will make more sense!
VFR lighties do not need to gain anything for day to day use, however the benefits when needing help, be it weather, navigation or emergencies will be there and over a greater proportion of the country.
And the diverted expenditure on En-Route Radar would allegedly pay for it.
And for the negative mided folk, terminal radar will always remain.
