The irony is he has handed ASA a silver bullet to shoot down noise complaints.
"Is it true you had 53,731 noise complaints last year?"
"Yes, but 21,411 were from one person, [meaningful look, nudge nudge wink wink, know what I mean, this guys obviously a crank, big brush to tar all complaints with etc]"
Last time I looked at my engines on descent into Perth (or anywhere else for that matter) there were already at Idle.
I 'm glad I'm not the only one confused by this 'new' idea. I went though the ATC training college nearly 25 years ago and we were taught than that the goal of arrivals was to give unrestricted descent from top to landing (even if its not always possible, its always the aim).
