2tonne Posted January 14, 2016 Share Posted January 14, 2016 I like to think that I fly reasonably tidy circuits. But, a while back I used my GPS watch to track my circuits and they look a bit looser than I would like! See the attached pics. One is the GPS track and the other is the altitude. I know that the altitude tracking on GPS watches is not real crash hot, but it does seem to show that I am wandering up and down a bit. Must practice more.

turboplanner Posted January 14, 2016 Share Posted January 14, 2016 They are pretty good circuits 2t! 8 Link to comment Share on other sites More sharing options...
Geoff13 Posted January 14, 2016 Share Posted January 14, 2016 You seem to have nailed that upwind leg pretty well. It like you were following a line on the ground. LOL Link to comment Share on other sites More sharing options...
2tonne Posted January 14, 2016 Author Share Posted January 14, 2016 Thanks TP, I thought the turns should have been closer to 90 degrees, but perhaps I was not accounting for the drift properly, maybe overcompensating. Sometimes at Redcliffe though you get a wind in the opposite direction to that at ground level while you are at circuit height. Geoff, yes at least the leg that counts most was a straight one!

Pearo Posted January 14, 2016 Share Posted January 14, 2016 I reckon thats a pretty tidy set of circuits, CPL standard. I love when the windsock shows and easterly breeze, but its actually westerly. The windsock at YRED lies. I departed on 07 on Wednesday morn, windsock showing an easterly, but rolling down the runway you figure out pretty quick its a tail wind.

Get the ARO to fix it ! ....... Bob Link to comment Share on other sites More sharing options...

Phil Perry Posted January 14, 2016 Share Posted January 14, 2016 You seem to have nailed that upwind leg pretty well. It like you were following a line on the ground. LOL What ? ? you mean you guys DON'T have ground lines to follow at your airfields ? ? ? ? Respec ! Seriously, at some airfields up here, particularly the smaller / country strips, it would help !. . . "Don't fly downwind for zz past that clump of trees for chrissake, or they'll be on the phone, Don't extend over that lake, . . .you'll frighten the pigeons / Swans / newts / whatever. . . and keep well inside that boundary road or you'll frighten the cars. . . " . etc. I guess you may well have a few places like that also. Some of the caveats in the Lockyear's UK small airfields guide; have voluminous instructions which take longer to read than it does to fly there. . . .this is OK for the residents, but concentrates the grey matter for first time visitors. One airfield called Arclid, not far North of my site, has a rule whereby each departing aircraft must adopt a specific departure "Radial" and there were 5 of these, . . ie, each departure must rotate to the next radial to spread the noise evenly around the neighbours . . .this requires much diligence, and carefully noting which way the preceding arcraft went.

pylon500 Posted January 14, 2016 Share Posted January 14, 2016 Your ground tracks actually look pretty consistant, especially with turn points over water. One would normally assume you were doing left hand circuits, although the squeezing effect at the top right hand corner would suggest a gliding turn onto base? The height profile is interesting... You can glide better than your climb rate, which indicates a pretty good climb, are you in a Foxbat? (Just looked at your profile, I guess this was in the CTMC?) The little climb at the end of each downwind just before the decent would suggest pulling on flap while still a bit fast? It is also good to see real glide approaches, getting your circuits down to the 4~5 minute mark. Keep at it... Link to comment Share on other sites More sharing options...
kgwilson Posted January 14, 2016 Share Posted January 14, 2016 I did the same check about 20 years ago with an old Garmin GPS II which just had a breadcrumb trail & it looked surprisingly similar to both the examples shown here. So I'd say they are as good as most get. Every one will be a bit different as the wind rarely stays absolutely constant & there are heat bubbles moving you around a bit. The GPS will pick all this up but with the instument damping or lag your VSI & ASI won't. Link to comment Share on other sites More sharing options...

The aircraft was a Tecnam Eaglet which does have a pretty good climb rate. I think the slight climb just before the base turn is pulling the stick back to slow the aircraft to flap extension speed. A lot of the approaches in the Tecnam are glide approaches, because gliding is something it does well. Link to comment Share on other sites More sharing options...

Jabiru7252 Posted January 15, 2016 Share Posted January 15, 2016 Your track looks pretty similar, is that a right hand circuit as well? Yep, RH circuits. The tighter circuit is the ideal circuit, the rest were a bit wide. This is because I was just starting out in the Jabs after previously flying the Tabago TB10 and Piper PA28 .

Bruce Tuncks Posted January 18, 2016 Share Posted January 18, 2016 I reckon they are good and consistent circuits, better than mine. And if you have an engine failure on the circuit you won't go down among the houses. And you won't surprise a glider by coming up behind him on finals.

Kyle Communications Posted January 18, 2016 Share Posted January 18, 2016 I wouldnt be complaining 2Tonne I think that is super consistant ....there are a lot more flying here at caboolture that wouldnt come close to that...and we have good reference points here not ocean a fair bit of the time Mark Link to comment Share on other sites More sharing options...
