"Just imagine the Possible effect that might have on confusing other circuit traffic. and especially someone going around who got too close to preceding traffic on final.. Nev" Yes, well the reason this thread got started is that we have several of our own having recent near misses in the circuit when everyone involved thought they were doing things by the book. So there's plenty of room for confusion anyway as it stands.

And I see it's sometimes done on the 'dead side' waiting for a gap to open up in the flow.

Likewise, the training area "clearing turn" has always struck me as more of a Hail Mary than an effective "clearing" of the area. At best, it consists of maybe a half-minute look-see over that way then the same over the other side before launching into many minutes of often heads-down concentration on a given set of manoeuvres; instructor and student, both, happy in the knowledge that the sky is (by rite) theirs. And yet every mid-air threat I've ever witnessed has appeared from nowhere and flashed past in seconds countable on one hand. And that does seem to be the experience of most near-miss 'survivors'; there are dozens of videos on the Tube where you actually get to see frame by frame how difficult it is to see collision course traffic even fifty metres out. That's not to say that a 'clearing turn' might not, one day, save your bacon. It conceivably could. (Anyway, not 'doing the honours' on a test flight will surely get you excommunicated.) But, to convince yourself that you've 'cleared the area' just by going through the motions is irresponsible. Lately, in online aviation videos, you do see instructors backing up 'clearing' turns with EFB traffic displays which actually can be relied on to detect nearby threats. But, that's in the US where ADSB is now close to universal. Typical instruction in the customary method: https://www.youtube.com/watch?v=cZJXQpF5bcg

Yeah, that'd be old Capt. Straw-man and his mates; they say a lot of crazy stuff.

Which is comforting.

BTW, for any Avid Flyer fans who haven't caught it yet, this is a nice (24') video on it by Jonas Marcinko

I agree. The problem with AvTraffic's internet based "ADSB" targets in OzRwys is that they show up in the same dark blue that's used for direct ADSB traffic such as supplied by the SkyEcho2. OzRwys traffic (its own participating customers, via internet) is, of course, distinguished by showing as light blue. A couple of years back I had an email exchange with OzRwys support suggesting that direct ADSB targets might be better displayed as a different colour (as opposed to just a darker shade). I was told that they felt the distinction was clear enough and that since "traffic is traffic" it's better, for a consistent iconography, to keep the two types the same basic hue. But as you suggest, Glen, traffic ain't traffic when lag is involved. So I reckon it's time to move to a different colour for true ADSB (real time) traffic.

It might sow confusion if we throw around term "traffic display" without being clear that we're talking about cellular network based traffic systems and not about proper ADSB-IN displays. Sure, any internet lags become clear on your EFB screen if you're running proper ADSB-IN at the same time. The position delay seems, in my experience, to vary from zero to several seconds. But just to be clear, there is no latency issue with true ADSB-IN traffic displays (like SkyEcho2 or better). And usually, when we're discussing the use of traffic displays in the circuit - for or agin - we're talking proper ADSB-IN That being said, Area-51's story, a few posts up, shows that even laggy cell based traffic (like his AvTraffic/OzRwys integration) can sometimes work better than any amount of "managing separation visually" : "After one more recent near miss, have upgraded the situational awareness by taking out a paid subscription with AvTraffic ... it paid dividends. The first flight afterward saw almost the exact same scenario with the very same other aircraft, however this time was able to see the situation unfolding well in advance, so simply turned away." OzRwys is clear about the limitations of its cell-based display of traffic information. As they put it "OzRunways traffic is great but it's not the whole picture" before going on to urge customers to invest in a proper ADSB-IN solution. But short of one of those, an AvTraffic/OzRwys (cell based) set-up does have a few plusses of its own, combining OzRwys targets with all other traffic supplied by the 'ADSB-exchange' (most ADSB-OUT equipped aircraft - depending on local coverage) and presenting it all on the familiar (already in use) OzRwys main map page - without need of other devices. Plus AvTraffic has aural traffic alerts. And while those alerts are probably very useful enroute, I can't see how they'd help much in the circuit; wouldn't Bitchin' Betty be having constant conniptions even in a mildly crowded circuit area? I suppose time stamps could overcome lag issues in internet traffic displays (as long as pilots didn't have to do any maths in their heads, when only a glance may be spared) but wouldn't it just be putting lipstick on a pig? ADSB is here - it's an amazing aircraft-to-aircraft tech which just works, is user friendly and is heaps cheaper than it used to be. The problem remains that it's far from universal in VFR land. Too bad the proposal before government years ago for supplying devices free for all VFR aircraft wasn't taken up.

Port is fairly busy with quite a few RPT flights (including Bonza's 737 a couple of times a week). So good practice for busy circuitry. Camden Haven is a beautiful place and great strip. It's under new (private) management, so not sure of PPR status. However, it's quite isolated from nearby towns without a car. Old Bar, 35nm down the coast, is a great strip to visit. Easy walk to town, the beach, eateries etc. Caravan/cabin park adjacent. Strip is shortish grass (580m) but a well maintained strip. All circuits to the east. Might be a bit daunting if unfamiliar (crossing sea breeze; trees at north end; sports oval lighting along the western edge). Taree is just 5 minutes flying inland along the river from Old Bar. That's where you could get fuel and find a CFI - GA/RAAus - for a local area briefing (if desired). YTRE's main strip also handles some RPT but it's way less hectic than Port Macquarie. Plus, it's the home field of AAK (Australian Aircraft Kits) where the mighty Hornet bush plane is made. It's also the home of Taree Wing where our own Pylon500 is the RAAus instructor (also maintainer and designer/builder of various types). YTRE also has a caravan park a short walk away fro tie-down.

Speaking of which ... I just asked old mate "Student Pilot", who is currently in Turkey doing fire work in an AT8, to send some pics. In this one he's keeping an eye out for golf courses in the city of Adana. (But then, he is behind a turbine. ;- )

Yes, I mean it as the obverse of 'nothing succeeds like success'. You feel you're failing in something - which you might normally be able to easily correct - but the fog of failure disables your problem solving ability. Just another way of saying 'panic sets in', I guess.

Yeah, I think that 'stress-hormone' explanation is well illustrated is this video I've just seen of a bounced landing of a Citation in Oklahoma. The YT vid includes the pilot's own written narrative of what happened and he explains it in very similar terms. It also shows that it's not just us low-time pilots who face it; it's anyone who finds themselves suddenly outside their zone of feeling 'in control'. Once you slip into the 'yellow zone', as this pilot calls it, things tend towards red - because, after all, nothing fails like failure. https://www.youtube.com/watch?v=1C5QqAhYL50

On the other hand, the whole world got behind the Thai soccer lads in the cave. (Heck, even Elon wanted to help by having SpaceX design a rescue-sub, before he was (appropriately) told to butt out.) And this paper from the European Parliament puts a bit of meat on the bone regarding the Mediterranean tragedies. EPRS_BRI(2022)733712_EN.pdf

But I guess the worst part is that you straddle the centre-line! ;- )

They can't be persuaded to at least go for Electronic Conspicuity (SE2) at $500 a pop (subsidised)?

Yeah, a busy circuit is more akin to city motor traffic conditions than any chunk of big-sky. Everyone is, by design, on the same level, which is both good and bad. (Visibility is often less reliable in the air.) TCAS doesn't apply either. It'd be screaming spurious Resolution Advisories at you constantly. Some kind of ADSB CDTI (Cockpit Display of Traffic Information) doesn't need to be cluttered to show you any converging threats. And contrary to the straw-man objections you don't need to be staring at it any more than you stare into your mirrors on the road. In Glen's case a mere glance would have picked up that other aircraft on a wide circuit - if only it had been equipped. (After all, he was expecting it to be ahead of him but already on base. Your MkI eyeball can't 'look' at the whole scene like a CDTI can.)

My takeaway from Glen's story was that the old MkI Ball needs EVERY BIT of help it can get, when it comes to avoiding midairs. Which is what the safety authorities have been on about for yonks; most recently by way of urging (subsidising) voluntary VFR ADSB uptake. And, yes, luck is in large part self-made. (Though, in these cases, universal uptake would be the greatest luck of all.)

Yeah, well, I'm full of curiosity as to the colour of my BRS. Will I ever see it!? Imagine buying a $9000 dollar item and never getting to post an unboxing video on YouTube.
