I guess it boils down to how many times you want to roll the dice with RPT jets with150 plus pax on board.
AirServices review of airspace around Ayers Rock is a revelation into the way they think.
Fortunately , in some cases such reviews have reversed previous idiotic decisions such as the reopening of the tower at Karratha.
But its still rolling the dice. Personally I think all non-radar CTAFs servicing RPT jets with over 100 seats should have a tower. Period.
But , of course , this is Australia.
Its never going to happen.
Until..............
