......So basically light aircraft are required to fly over water to satisfy the RAAF?

In the same way light aircraft are required to fly over water down Victor 1 to satisfy ASA, yes. The big difference though, is ASA makes things easy. Wear a life jacket, fly this route, not above 500' and you don't need to talk to anyone as you fly within a few miles of one of the 'busiest' airports in the country...

Good luck with that at Williamtown...

Realistically, what are the chances that UVC will be found?

The sod 12th Sep 2019 00:05

Was the helicopter registered in the "Limited" C of A category.? Are Limited aircraft approved for NGT VFR ?

It’s nearly 5nm from the thresholds of 34LR to V1 on rwy track for an aircraft departing 16.

Less than 3nm from the (new) threshold of 30 to the drink for an aircraft departing 12.

So yeah, good luck with that!

junior.VH-LFA 12th Sep 2019 00:32

There’s also a heap of low level fast jet traffic that arrive via the coast.

It isn’t the same as the V1 so it’s not really a fair comparison.

From photos online it is in the Limited category so no more than 6 pax. As far as NVFR instrument requirements under 20.18 im not sure. Depending on its Limited category index number it may or may not have been approved to fly over populous areas as well? No doubt all will come out in the report.

Please put a probability number at the end of this sentence:

The probabilities of an aircraft inbound to or outbound from Williamtown colliding with an aircraft that is identified by and in contact with ATC and tracking at 500’ over water adjacent to Stockton Beach off the extended centreline of runway 12 are [please insert a probability number].

Your use of the word “luck” is appropriate. That’s the basis on which so many decisions seem to be made in this Galapagos. You have to be lucky enough to get into the head of someone who understands objective risk rather than perception and intuition.

BTW: How confident are you that Romeo 578B - i.e. outside the 12nm arc from Willytown - was active at the time UVC arrived in the vicinity of Anna Bay?

You know you could just check the NOTAMs to see its active everyday right? - 100%

Limited Category

belly tank,
Contrary to popular lore (as opposed to law) Limiter Cat aircraft are NOT limited to 6 persons or pax.
Read the AC a little more carefully.
Tootle pip!!

You mean the NOTAMS that say:

TIMES MAY VARY AT SHORT NOTICE. PILOTS RESPONSIBILITY TO CK AND MNT STS. ACCESS TO A PRD AREA MAY AVLBL IF THE ACTIVITY FOR WHICH THE ACTIVITY HAS CEASED (EARLY DEACTIVATION)
Those NOTAMS?

Your “100%” confidence that R578B was still active late on Ronnie’s POETS day is noted.

Call em up if you want (the number is there in juniors AIC link funnily enough), the 578 series is active every day til 10pm - the only time manual deactivation happens is if the airspace happened to be active past 10, in which case the airspace won’t deactivate any earlier than 10 anyway or if there was some sort of apocalyptic style event that scared all the controllers away - in which case there would be 0 mil airspace (including CTR).

Lead Balloon 12th Sep 2019 09:32

It follows, therefore, that UVC was under air traffic control before it arrived in the vicinity of Anna Bay, as UVC was in an active Romeo. Correct?

Maggie Island 12th Sep 2019 09:38

Yeah UVC wouldve had a clearance

KRviator 12th Sep 2019 09:43

Am I the only one thinking UVC may have violated the Willy CTR without clearance and that might go some ways to explaining his fairly rapid turn out to sea?

ADS-B Exchange has the last ADS-B plot at -32.804943, 152.043326, which appears to be the second-last one FR24 recorded, based on altitude, but it's closer to Williamtown. When you plug those coordinates, and those of the WLM TACAN into a few different Lat/Long distance calculators, you come up with 11nm, according to the US NOAA, or 19.66km / 10.6nm according to a couple of others. The CTR extends 12nm from the TACAN, so is it possible he feared a pineapple for busting their airspace?

UVC wouldve been inside controlled airspace from Broughton Island which is ~ 12nm up the coast from Anna Bay. Some of the news reports say that he was in communication with ATC (though it doesnt specify WLM...) but I think its pretty likely that UVC had requested and was subsequently granted a clearance to WLM at about 3000’.

Lead Balloon 12th Sep 2019 10:07

You keep saying “would have been”. Do you have first hand knowledge of whether UVC was under air traffic control before arrival in the vicinity of Anna Bay?

Not “would have”, but was in fact.

No idea - but any other aircraft in that position at that altitude would generally have one.

Lead Balloon 12th Sep 2019 10:29

Righto. Good to get an acknowledgement that you’re merely speculating. Like the rest of us.

Actually CAR 262AM states WHR ( warbirds and historical aircraft ) are limited to 6 persons on board, an application to carry more can be obtained. What would you call the UH1H ? I’d call it a warbird under CAO 104 and it was in the Limited category to which those regs refer to.
