During that approach and at about 15 kilometres from Avalon the jet was tracked as descending suddenly to as low as about 1600 feet at a point where the minimum safe altitude is 2500 feet.
All Tiger pilots being retrained under conditions imposed by CASA on its AOC.
The question is how far was the aircraft from the 36 runway threshold when it first descended below 2500'? Quoting Ben Sandilands, 15Km= 8.1nm. I am not sure where this data comes from, however,
if it is correct then this would constitute operating below LSALT at night in contravention of the AIP.
