Clearedtoreenter: SBAS coming our way? Pigs might fly. Would be nice though.... A 3D coupled approach into Bankstown... Dreamin
You may well see those pigs fly.
WAAS (SBAS) is highly likely to come downunder, and not because of aviation but because it is an enabler for other transport systems e.g driverless vehicles and other technology to do with terra firma based transport. Aviation will be a relatively small user.
Right now NZ and OZ are about the only two places in the world without an SBAS system or immediate plans for one.
I'll stand back now and wait for Tom Imrich to pitch in and give his anti SBAS point of view.
