Perhaps someone can explain to me why it is apparently OK for a chopper to fly an instrument approach to an unlicenced aerodrome, but not a fixed wing aircraft?
The approach looks straight forward to me, and the Bonanza can easily operate into and out of that aerodrome.
A straight-in RNAV approach onto the ATN runway has to be safer than flying part of the Mareeba RNAV approach and then breaking off to grope your way to ATN.
