I am not an instructor, but a coach. I've been flying since 1980. Instructors could be correct, their concern is someone pulling the nose up to try to make the landing point and stretch the glide on final turn. My two comments would be. 1) Thermalling I don't pull the speed back when maneuvering to find the core as I like a bit of extra speed to have maneuverability. 2) if you are on final turn to land and want to make the air field and you are concerned about making the field, point the nose to the top of the fence, you will always make it. If you are going to fast then you can pull the speed back and use dive break. In both cases no chance of spin or stall. If you can't make it then you are in the poo.

Great instructions about how to fly accurately. I'm surprised about the "full rudder" and the "top rudder" bits. I think we all have to find out how our specific glider needs it. Some gliders have a lot of rudder effect and some less and som rolls really well into the turn and some not so much. I would max the weakest and coordinate with the strongest to obtain the highest achieavable roll-rate. And the top rudder - this is all new to me. I only used that for knife-edge manouver and for side-slip to land. Otherwise my rudder was allway a bit into the turn, and never outside neutral. I can't wait to try this out - and I will, because you are a much more accomplished pilot than myself.

Thanks James. I am a recently solo glider pilot working my way towards my Bronze and Cross Country endorsement. I'm in exactly the position you describe. I've been taught to fly safely (very important of course!) but without doubt the most important thing now for me to learn is to be able to thermal very well as this after all in the flatlands is what keeps us in the air! I've found your video extremely valuable and I have learned many things which I look forward to putting into practice once this Covid-19 nightmare is over and we're back flying. Fly safe and thanks for taking the time to make the video!

@@andrewstout9321 Fundamentally, the reason he is not close to spinning is because his speed is well above the stall. With speed close to or at the stall, an ASK23 glider will spin if you try to get the yaw string to the centre; it will not spin if the yaw string points outside the turn as recommended here. See There is a KZitem video which demonstrates how a spin can be induced from a thermal turn with too much into turn rudder: see kzitem.info/news/bejne/kmyenZeObpaQf6w. However, He only has full rudder very briefly, and with the speed well above the stall and the stick is not right back.

Sorry that comment got posted by mistake while I was in the middle of editing it - but most of what I wanted to say is there. I also think he uses full rudder to roll into the turn partly because of the glider he flies. I fly a glider with powerful aileron control and would not use full rudder - I roll into the turn using co-ordinated aileron and rudder.

I calculated the ideal angle the yaw string should point to the left in a right turn. Depending the cg the other values, it is about 1 to 2 degrees. So, I can't confirm the rule of thumb, that the yaw string should point to my left shoulder. It is way too much. Keep the yaw string center and your are fine at any time.

Thanks for getting back. I used to fly in the UK but left in 87. Quite frankly I have forgotten what the thermal structure was like, and as I flew an Olympia 1 half the time and a cobra the rest. I understand you have thermals that are not strong, but what i see with novices in Aus if they don't fly accurately they don't get the strong climbs. They get the strong sink on the edge and end up in a paddock just as quick as a pommy pilot can do in England. We may be chasing 500, 750, 1000 we have to fly very accurately. You may be chasing 100, 200 300. You have to fly very accurately. Happy Safe flying

The best and easiest way is to get a piece of paper, A4 is good. Fold it diagonally top edge against side edge, make a nice crease and then open the paper back out again. Now stand in front of the glider, straws approximately in place. align the crease in the paper with the fin, and adjust the straw to the edge. You can get it right within a few degrees. Remember it is good to keep 45° but if you are a degree or two out it does not matter. What matters is that the bank is constant all the way round.

Amazing video! Just excellent tips for thermaling. Recently I am a flight student in Germany with the aim of getting a successful cross country pilot after I received my license. Your points are completely understandable. Flying circles with a constant bank angle is not complicated in my opinion. If the thermal is getting rough or one has to deal with wind speeds it is not so easy anymore holding the angle. One also has to correct the angle with aileron to stay in a constant steep turn. My flight instructor calls this paddling and says those corrections cause to much drag and it is not efficient, moreover, he complains about the thread not being in one line. What is your opinion? (I only make small corrections) One question: Do You have your rudder in a constant position while thermaling or do you also use it for corrections? Keep it on! You really inspired me, thanks for sharing your experiences and knowledge with us! Greetings
@jamescooper7743

When conditions are rough the air speed appears to fluctuate. The issue is not that you are flying fast and slow but you are getting horizontal gusts. So the best thing to do is not to fight the speed but maintain the attitude and bank angle and let the Air Speed indicator fluctuate. I have heard instructors say that moving of the stick causes too much drag, I am not convinced. but what you describe as paddling is perhaps just chasing the unchangeable. See above. With regard to corrections I use the rudder as priority to kick into the turn, not the ailerons. It goes against the grain and theory but the rudder's secondary effect will turn the aircraft the ailerons have adverse yaw. Could i suggest that with a little bit of subtlty you aproach a good cross country pilot and have a fly with them, if they are successfull at cross country their skills at flying will probably be good. Instructors who just fly local can be good but I believe do not have the skills of good x country pilots. Keep in touch. ( looks like i will win OLC Australia this year.)

Excellent video. This pilot, and others, recommend rolling into the turn when you cease to feel the upward push. I turn before that - generally I will have felt a bit of push, slowed down, and then if I feel a strong push when the vario was already showing lift I turn. Given the time taken to enter the turn, with luck ! I find myself turning in the core. If I wait until I no longer feel a push I think I will have missed the core. What do other experienced pilots think? (I'm a UK instructor and cross country pilot).

Thanks for the comment. It would take ages to go into how to center the thermal in the first turn and then maintain it. Perhaps I should do that one day. But the purpose of the video is purely to inform the pilot how to make the turn. Even though it is basic stuff it appears to be something that is missed out in training. There appears to be an assumption that pilots can make that first turn correctly. Anyway a few others have made the suggestion how to find the core and keep it. Perhaps I will try to put something together. Thanks

There are two things that will help you progress. I study and knowing what to look for. Clearly you are doing this. I read a Piggott book before I sat in a glider and 7 other books shortly after I was Solo. The other thing is practice, after about 1000 hours I was beginning to get the idea of things. Yes sometimes I just feel that the thermal is over there and I don't know why. Practice I guess. There is a third. Speak to those who know. With all respect that is not always instructors. Check out the good pilots who prove themselves by their results. Most are happy to pass on their info. Sap it up like a sponge. I should have another KZitem later this year on thermalling and sources.

Brilliant, idea I never thought of that one. Don't tell anyone else. The big problem is that in Australia once you get a hay stack fire the fire spreads very fast, the visibility reduces and you can't see the person you are following, for the smoke. We will have to find a way around that. But let's work together on this one.

It is interesting sometimes when i am thermalling i move across to somewhere just because it feels right and I have little idea why. However the Gliding Federation of Australia have just put into place a training system where all instructors and coaches teach exactly the same way, including patter. I believe that they have done a very good job and you can get their thermalling technique on line doc.glidingaustralia.org/index.php?option=com_docman&view=tree&slug=training-manual-part-2&Itemid=101 this is for novices and is based on "Not Loosing the thermal" which is not necessarily "Getting the core" Have a look at the pilot guide. There is one additional comment. If there is a reasonable amount of wind there will be thermal bubbles and very narrow streets that lead to the thermal. You can not thermal in the streets as I guess they are about 30 m wide. have a look at my web page if you have not already done so there www.jamescooper.com.au/Gliding/gliding.htm There are a number of articles there that may be of interest

The reason for a bit extra speed is to give maneuverability. So as the thermal gets smoother and you have no need to have that extra speed. I dont know where you are from and what your thermals are like. but early morning in Western Australia the thermals are tight and rough. Have speed. Late in the evening they are week but large and smooth. bring the speed back and even flatten out the bank a few degrees. Safe Flying James
