That’s not exactly what I stated.

Without getting into a debate, I know that the Airforce take risk mitigation very seriously and certainly don’t take short cuts when it comes to safety.

Obviously certain operational tasks are assessed differently with regards to risk, e.g. peacetime activities in comparison to a conflict situation.

We won't get into a debate because there is no debate. It is exactly what you stated.

I said: "You know the RAAF flies low and close to terrain occasionally, right? Even when it's dark."

You said: "Totally incorrect in 2023, possibly was the norm years ago however it certainly doesn't happen today."

If what you meant to say that the norm in the RAAF years ago was to fly low and close to terrain in the dark, while taking short cuts on safety and not taking risk mitigation seriously, you'd be wrong on that, too.

Those reports have nothing to do with the airspace. However, the presence of ATC was clearly a factor in avoiding a more serious incident.

I would lean to a poorly designed STAR that allowed a discontinuity where a critical altitude is inserted. Which then adds to the airspace procedure flaw input into the incidents.

The ADF helicopter that most recently crashed into the ocean at night, may have been flying a mission close to it.

Indeed. Sadly, there is no such thing as risk free flying activities, despite taking safety and risk mitigation seriously.

You can take off down the valley without a GPWS

Dicussion of RAAF operations irrelevant.

This was a USAF C17 long range Transport flight to HNL, not a tactical mission.There is an image of the aircraft at 1500FT approx 1NM west of Mt Yarrabah.

All the other armchair commentary becomes immediately moot .

You can with one too, on the now defunct RNP departure that was canned for a single noise complaint.

By image do you mean radar image / paint?
And night presumably (as opposed to IMC)?

There is an image doing the rounds, I assume it is some kind of radar screen grab, showing the aircraft at 1500FT at 270GS with a Controller alerted Below Minimum Safe Altitude Warning in the vicinity of Mt Yarrabah. As there was apparently no ATC service, one assumes the alert went unactioned?

If that’s the case then they would’ve departed off R15 and made a very lazy left hand turn and come too close to the terrain there at 1500’ in an MSA sector of 6500’. Like I said before impossible to miss the multiple warnings on the basic DAP charts.

No kidding. If it reported as true (and not a NVMC dep with toys we don’t get to play with) then yes the crew clearly had a moment, but this thread is not about them - although I’m sure there are some internal learnings that will come out within their system.

But in a normal first world country there would be ATC guidance / alerts that would have prevented this from escalating.

Where was the controller?

You should be able to pull archived tapes from LiveATC if you know a date.

I recall seeing a C17 parked with a Omni 767 about 10 days ago.

I’ve overlaid the screen grab onto the 1:250k topo and reckon they had 300’ of air under them.

What date and time? Are you able to post said screen grab?
