Parkway Posted August 23, 2016 Share Posted August 23, 2016 So I don't think we use these very often here in Australia, but it's still in the study material.. Anyway these two diagrams seem to contradict each other, wondering which is correct? I thought that the "L" indicates the base and final segment, like it seems to be represented in the diagram on the right. But on the left diagram that would mean both runways would be right Hand circuits but the caption says left hand circuits? Confused Link to comment Share on other sites More sharing options...

Nightmare Posted August 23, 2016 Share Posted August 23, 2016 The best, and official, circuit indicator is ERSA. If there is any change to this, look at NOTAM's Link to comment Share on other sites More sharing options...

CAV0K Posted August 23, 2016 Share Posted August 23, 2016 Look at it as the upwind and crosswind leg .. that way all CCTS are LH on the left diagram. Hope this helps 1 Link to comment Share on other sites More sharing options...
Happyflyer Posted August 23, 2016 Share Posted August 23, 2016 As stated above. The 'L' represents upwind and crosswind. Link to comment Share on other sites More sharing options...
Parkway Posted August 23, 2016 Author Share Posted August 23, 2016 Oh yeah. Really obvious. Don't know why I had it in my head that they represented base and final. Thanks guys, feeling kinda dumb hahaha 1 Link to comment Share on other sites More sharing options...
Nightmare Posted August 23, 2016 Share Posted August 23, 2016 You can also think of it as the pointy bits are pointing to the live side Link to comment Share on other sites More sharing options...
red750 Posted August 23, 2016 Share Posted August 23, 2016 Interpret them like roadside turn signs. If taking off in the direction of the top red arrow, it's a right turn, therefore, right circuit. If taking off in the direction of the lower red arrow, it's a left turn, therefore, left circuit. 2 1 Link to comment Share on other sites More sharing options...

Thanks guys, feeling kinda dumb hahaha Glad we could help! Don't feel dumb, we as pilots are always learning. At least you took the initiative to ask for clarification of something you were unsure of. Good luck with your study. 1 Link to comment Share on other sites More sharing options...
DWF Posted August 23, 2016 Share Posted August 23, 2016 Has anyone seen this ground signal in use at any airport in Australia? I haven't, and I have been to a fair few of them. Link to comment Share on other sites More sharing options...
ben87r Posted August 23, 2016 Share Posted August 23, 2016 Never seen or herd of them. Don't dislike the idea tho, it's effectiveness would be limited tho. Link to comment Share on other sites More sharing options...
Blueadventures Posted August 23, 2016 Share Posted August 23, 2016 I haven't seen the diagram. However at Palmyra airfield up my way all downwinds are the western side of the 36/18 runway because it is located very close to the controlled airspace of Mackay. Therefore any wide downwind to the east would be in controlled airspace. Link to comment Share on other sites More sharing options...

Therefore any wide downwind to the east would be in controlled airspace. See the diagram in post #4 above. The 'normal' circuit direction is LH, however there are quite a few airports that have a RH circuit specified; usually to keep aircraft clear of terrain, airspace or noise sensitive areas. In some cases the circuit direction is different for day and night ops. Link to comment Share on other sites More sharing options...
Parkway Posted August 23, 2016 Author Share Posted August 23, 2016 In the book it did say that these markings are more common in the US but I thought I better get it in my head just incase it pops up in the exam Link to comment Share on other sites More sharing options...
Nightmare Posted August 23, 2016 Share Posted August 23, 2016 Has anyone seen this ground signal in use at any airport in Australia? I haven't, and I have been to a fair few of them. I saw one in a YouTube video of a Clifton Fly-In once. I have flown into Clifton but didn't see one.... It must have been there only for the fly-in. It's around 6:50 Link to comment Share on other sites More sharing options...
Stoney Posted August 23, 2016 Share Posted August 23, 2016 Has anyone seen this ground signal in use at any airport in Australia? I haven't, and I have been to a fair few of them. Port Lincoln Aerodrome YPLC has these indicators - LH circuit one direction but RH circuit the opposite way. It works quite well, the terminal buildings are always the dead side.

DWF Posted August 23, 2016 Share Posted August 23, 2016 At Port Lincoln SA the arrows are at the end of the runway and only indicate that there is a RH circuit on a particular runway. The RH circuit indicators are at BOTH ends of the runway. This is not how it is described in the book and seems to be a non-standard use of the markers. There are no markers near the windsock! The ones for the gravel runways are a bit difficult to see. DWF Link to comment Share on other sites More sharing options...
Soleair Posted August 24, 2016 Share Posted August 24, 2016 In the UK the runway direction is indicated by a Tee. You fly up the leg toward the cross piece. A big white Tee is on the ground near the windsock, at nearly all airfields. I once flew into Popham from the Isle of Wight and landed into the wind. The airfield manager came out & threw a wobbly because I'd landed against the tee. . . Link to comment Share on other sites More sharing options...

I certainly haven't, DWF...what's wrong with "All circuits to the south"? Kaz Link to comment Share on other sites More sharing options...
Nightmare Posted August 24, 2016 Share Posted August 24, 2016 I certainly haven't, DWF...what's wrong with "All circuits to the south"?Kaz Not sure what you mean by this kaz? Are you suggesting that that the live side of all circuits should be to the south? There may be issues with that, like noise sensitive areas, low controlled airspace, etc. I still say ERSA is the only official indicator of circuit direction. Any ground signals should be secondary to it. Link to comment Share on other sites More sharing options...
