Folks,
WAAS has been mentioned, that would have been of marginal help at MIA, as the minima for a WAAS PVA ( or, at least, the published ones I have seen, have all had a 300' DH, viz. around 1200m. I believe it is possible, but I have never seen, a published WAAS PVA to 200'.
Yes, there have been research testing autolands with a LAAS, but I am not aware of any such approaches in service or any airlines contemplating WAAS/LAAS auto coupled approach /autoland operations any time soon.
Hell will freeze over before airlines would pay for a LAAS system at places like Mildura. Forget WAAS for Australia, a pity, but a realistic expectation. With new generation 3 GPS, now coming into service, slow moving users will have WAAS equivalent accuracy, without WAAS, leaving aviation as about the only beneficiary, over which to spread the cost.
Tootle pip!!
