How to avoid one glider pilot tactical mistake | Get high - stay high

[@SteFly]

Great video, which must have taken a lot of time to create and edit! The aggressive flying attitude is one thing but the most important thing is to determine in advance when you need to change the style of flying. When are key points to slow down, take a slightly weaker climb or join a gaggle. And of course it's also important to accelerate again after weak conditions when it is getting better.

[@glideraviator]

Oh yeah.. So much time! But many things learned on the process of creation. Thanks for recognition!... Actually thats what I was trying to say by this video. I mean that this aggressive attitude can very easily obscure your judgement to find those (as you say) key points. Event though you would know what to do when not influeced by this aggresivity or greedines. See ya at WGC... Stephan! 😉

A situation, decision, and analysis of result - this is absolutely golden for aspiring competition pilots!

[@glideraviator]

Thank you James!

Thanks for this great video and lesson. One additional thought to not fly into the turnpoint too aggressively would be that you had mainly tailwind on the way there and crosswind/headwind on the next leg. So I would consider this a "round the turnpoint as high as possible"-situation. Accordingly, a somewhat weaker climb on the downwind leg near the turnpoint is equivalent to a stronger climb on the next upwind leg. This tactic also includes cruising a little slower on the downwind leg close to the turnpoint. Chochrane explains this in his paper "Upwind and Downwind" and provides the theory for concrete wind speed and MC-settings. It would be interesting to do the math for this case. Of course this is not to say that I would have done it better. I have flown to aggressively many times as well. And I am not close to your average speed. So props to you, I think it was a great flight overall!

[@glideraviator]

Thanks for your toughts!!... Of course, the logic for weaker climb on downwind makes sense here, youre right. I read the Cochrane paper quite long time ago and I now feel a little bit stupid that I didn't at least mentioned this in the video. I wanted to point out the psychological aspect more. I mean the aspect of how hard it is sometimes to get weaker climb even if it makes sense to take it because of the greedines for high task speed is so strong. So here the link for Cochrane work (for potential comment readers): www.johnhcochrane.com/s/upwind_and_downwind.mht

Great video and insights to your decision making! Thanks!

I like these videos from glider pilots for glider pilots and not that clickbait shit we mostly find today when looking for gliding videos. Very good analysis indeed. One remark about the situation, it is nearly always difficult to fly from CZ into the higher terrain of the Lipno and Bavarian forest. There is nearly always a zone with bad thermals because the higher terrain sucks away the good thermals so here it is always a good idea to climb to max before continueing into the Mühlviertel or Bavarian forest. So your situation was absolutely typical. You even had luck that there where such nice clouds overhead the Lipno area, sometimes you have to get to the south side of the Lipno to find thermals.

[@glideraviator]

Yes agree about the difficulty of this area... But as I try to fly for the national (CZ) contest (www.cpska.cz) where the most valuable flights are declared FAI triangles Its often about doing compromises in finding the optimal declaration in accordance with forecast. I like this because it can be very challenging. And sometimes happens that I need to plan some of the turnpoints to "not ideal" areas like this one... On the other hand I can remember some flights thru area of Lipno where I was able to get to there without any trouble at all.. Thank you for tip! I aprecciate! Wish you safe flying!!

[@tadeksmutek5840]

Thank you for sharing this video - nice experience and good lecture presented. Good luck!

[@glideraviator]

Thank you, Tadek!

[@bbhima5814]

Enjoyed your video, thanks.

[@glideraviator]

Glad to hear it!

[@HruskinLKTA]

In the same area, I´ve made just oposite desicion - off course, get some height and than , abeam the turnpoint go for it with hight and tailwind., It worked prety well. I don´t like this area, it´s pretty commont to be in the shadow and overdevelopement :-/

[@glideraviator]

Hey Hruškin...Thanks for sharing your experience... Hope to fly together soon ;-)

[@wesk123]

Could you let me know what task software you are using? Thanks

[@glideraviator]

There is LX9050 installed in this particular glider... The screen you see in this video in lower right corner is just simulator of LX9000....

[@koenvanderputten867]

Turn it the other way around: Let's suppose you stayed in the 1,5 or 2m/s before the turning point and made it to the cloud base. And later after the turnpoint you flew straight into the 3,5 m/s thermal... You would be making a video on how you can speed up your average by not staying in the weaker climbs ;-)

[@glideraviator]

I think that in that case I wouldn't do video at all. Trying to avoid weaker climbs to fly faster doesn't need a video it's common sense 😉In that case I think that I would probably try to find another interesting topic or part of the flight to show...🤔

[@mattmatt245]

Will XCsoar show you maximum reach given your altitude, mc setting, wind and safety margin ?

[@glideraviator]

Yes It will... It's one of basic feature of all navigation software... But of course Its precision depends on quality of input data... For example It is good to have barometric altitude as source of altitude instead of GPS altitude...

[@mattmatt245]

@@glideraviator Are you running it on your cell phone using its pressure sensor for barometric data ?

[@glideraviator]

@@mattmatt245 I used to have XC soar or LK8000 software installed in my mobile phone connected with IGC logger via bluetooth. So it shared also barometric altitude.. But yes if your phone or tablet is equiped with pressure sensor it will probably work too. Nowadays I mostly use LX NAV solution.. Thats what you can see in the video...

[@mattmatt245]

​@@glideraviator Any major differences between LX NAV and XCSOAR ?

[@glideraviator]

@@mattmatt245 yeah... 😅Many major differences... XC SOAR open source software...(www.xcsoar.org/)... LX NAV - high end navigation computers... (gliding.lxnav.com/)

I'm a chicken 2:45 I would have stopped

[@glideraviator]

Sometimes it's vital to go out of your comfort zone ;-)

[@th3sly]

Nice content, but the high level of the music at the beginning and the end is very annoying

[@glideraviator]

Thanks for feedback... Now I started using different video editing software so I hope It will be easier to tame the volume levels in video next time...

[@quitypop]

love how you say meters just to stick it to americans, cmon bruh just say feet since its proper aviation terminology

[@glideraviator]

This will never happen, mate😂 I ve never flew a glider with imperial units. So why should I ? Beside your knots for climb rate vs feet for altitude doesn't make sense to me at all... I would maybe accept feet per minute for climb if you want proper aviation units😉 ... I think you should use some kind of unit converter same as I do when I study some american gliding material... Sorry but I'm not sorry😂

[@quitypop]

@@glideraviator nah I'm not American, I'm Australian and I use metric system in every aspect except flying. But it makes sense for altitude to be feet since it's more precise but nah all good.

[@glideraviator]

Yeah... I use the imperial units just for powered aircraft and its good there. For gliding the metric system is better I think. Mainly because the height with distance comes often to close relationship and its useful having it in the same unit...

[@stephanevdv]

Look up ICAO Annex 5, Table 3-3: feet, nautical miles and knots are only "Non-SI alternative units permitted for temporary use with the SI". The only problem being that there is no time limit to the "temporary". And don't tell me that feet are more precise than meters: the minimal separation between flight levels being 500 ft (152 m), that "precision" is totally irrelevant.

[@glideraviator]

@stephanevdv I kinda understand the "precision" argument because those feet altimeters has more sensitive scale usually. As one round of the needle means 1000ft (~300m) and one round of the metric gauge means 1000m (~3300ft). The feet altimeter is more sensitive then. (but not precise)... But no one really need this kind of sensitivity when gliding... So I agree It's irrelevant. To the air law note about ANNEX 5.. I have also found that in the 1978 the FAA actually agreed and stated decision to go for metric system... But in 1984 they took this decision back and cancelled...
