The objective is to get a good deal on the best wing available – for the purposes of the 2017 edition of the Red Bull X-Alps, and vol biv thereafter. As such I need to be confident on the wing, it needs to be suitable for a wide range of conditions and situations, and it should be a joy to fly.
I’ve always been a bit sluggish to upgrade wings, having flown my school wing (EN-A equivalent) the GIN Bolero+ for two years, then the Gradient Montana (EN-B equivalent), along with some second hand wings for everyday flying, until buying the Ozone LM5 in late 2013, which I have now flown for over three years. The LM5 was my first EN-D and I moved up after spending a year in Antarctica (not flying). I think that actively piloted it is the safest wing I have ever flown – I feel I have more feeling and control and the performance helps keep you out of trouble. The EN rating reflects on how the wing behaves in artificial conditions without correct pilot input, but in real conditions every situation has given me more confidence in the LM5. The caveat is the higher aspect ratio and cravats, as I discovered on my recent reserve throw.
I have not flown a two liner so my impression is based on that of others. They are a new development and the main problem is that while they do not collapse very often, they can be different beasts to get flying again when they do. The Ozone Zeno however, as far as I’ve heard, is comparatively easy to fly and I have not heard of any inflight incidents. Could it be that the wing design has matured, but the two-line stigma lives on?
Safety is a prime consideration, and one that has a question mark over it for the Zeno, but I do not know of any evidence to justify this. There is a school of thought that one should always fly a safer wing for the xalps than the wing you usually fly. Superficially this makes sense but when I think about the type of flying I do, predominantly solo vol bivouac in potentially marginal conditions and often in remote areas, it actually makes more sense to try anything new while fully supported, closely watched, and in a country with fully developed infrastructure. So you could say that the xalps is training for vol biv.
Performance is another critical factor. All else being equal, more performance gives you an increased safety margin. Glide performance gets you higher on transitions and arriving with just enough height to squeak through a col happens way more frequently than you’d expect, at least the way I like to fly. Speed makes a difference when pushing into headwind. But what people are all talking about is the Zeno’s ability to efficiently retain energy in weak or scrappy conditions. This would be an amazing attribute if you want to surf along the tops and ridges without topping up in thermals, which again is one of my favourite types of flying. It also might come in handy when working the scraps in the lee before crossing the mountain range. It’s tricky to assess performance because it’s like racing in between traffic lights – sometimes you get away and sometimes it makes no difference.
Handling is what I most appreciated about moving from the Bolero+ to the Montana. While at first the LM5 seemed boring compared to the Aspen3, when I went back to the Aspen3 recently I realised it really is a slow boat – notably I did choose a smaller size for the LM5 the second time around. I am really looking forward to the direct two-liner handling. I want to have wing that is poised on the edge of my fingertips. I want it to be nice to fly – it needs to generate enough excitement to keep me awake in weak conditions when I’m fatigued. In strong air I am not worried about fatigue, there is enough happening to keep me wide awake. Aside from inappropriate confidence levels, I’ve found that accidents happen when I am not attentive or engaged. When the air is rough I am very focused.
Aside from performance in the air, taking off and landing is a fundamental skill for the xalps. The zeno is a two-liner but I could hardly feel the difference when kiting it. I do not ground handle as much as I used to but I still have the skills and I can’t see the zeno being a problem. As for less passive safety, such as mushing it in to land in difficult conditions, I never really saw this as a good idea anyway and I have always tried to maintain a high standard of technique. In Annecy at the Planfait turn point I made a few passes before top landing but I made sure it all went perfectly. We’ll see if the easy handling of the LM5 has spoilt me, but so far I am looking forward to bringing the zeno into the air.
Finally there are the times when you have to carry the wing. The Zeno is a little heavier, but the difference in weight is not significant and I can handle that. More importantly is the bulk factor, and the need for it to be packed neatly to preserve the stiffeners. However I think that I have always packed my wings very carefully, and their lifetimes have been testament to this. So again I think this will not be an issue for me. In vol biv the extra bulk makes a difference but the weight is insignificant when compared to clothing and food, for example.
I would say we had good weather in Red Bull X-Alps 2015, as there was only one day I didn’t fly, and I probably should have. But many pilots complained of the rough and windy conditions. As an exercise I’ve re-examined each day to identify if wing selection was a factor.
- Day 1 Dachstein
- While trying to avoid airspace aggressively I think a small knot tied itself in my lines, which I had to land to clear. Avoiding airspace (or clouds) is something you would need to be very careful about
- After being overtaken I was able to catch the gaggle by using more bar and climbing less, with everyone on similar performing wings
- I landed after a long glide – can’t really blame it on performance though
- Day 2 Saalfelden
- Spent quite some time in weak conditions before getting enough height to get over the mountain. Perhaps the ability to surf up marginally better would have saved me a lot of time here
- I had a launch on a relatively flat area – a light wing with good performance would help here
- Day 3 Kampenwand
- Lots of soaring in weak lift and trying to get higher before making a crossing.
- Ability to climb in weak lift and a good glide ratio important, generally not pushing into wind though, so maybe not a big performance difference
- Day 4 Bavaria
- Carried my wing a long way. This was the lowest point for my feet – they felt a little tender as they got wet – but I don’t remember any back pain or discomfort. For these long walks you can offload all non-mandatory items, so weight can make a higher percentage of difference, but I don’t see a big advantage here unless you are running
- Day 5 Timmeljoch
- Some leeside flying in an unstable airmass (not particularly rough). No notable performance critical moves
- Landed after losing a few hundred metres of height, climbed up to relaunch. Packing and launching time significant here
- Very strong winds in some locations, extra speed bar may have made a difference in ability to push ahead, or may have simply provided more confidence
- Day 6 Tonale
- A glide on sunrise. No appreciable difference expected but if you are slightly higher you might be able to make a more convenient landing paddock – or you might have an extra wingover before landing in the same one
- A couple of relatively tricky launches where the wing had to come up quick and nicely
- Some slow conditions where I lost patience and landed before I should have
- Very strong valley winds and one of the least in-control landings of the race. Still on my feet with the wing fully open and overhead, but wind was swirling through the valley and there could have been rocks in the grass
- Prior to this landing, I had to change course on the crossing because I didn’t have the speed in smooth air to push ahead to the spur I wanted to. So speed could have helped in this scenario
- Day 7 Bernina
- Morning glides with somewhat questionable landings – tight with no margin of height, but the actual landings were ok (although I think I was too close to cow manure for the first one). Wing choice probably not a factor
- Very scratchy conditions before getting up – another chance for the Zeno to excel
- A face landing carrying the wing in a rosette – presumably a little more difficult with slightly more weight
- A failed valley crossing due to headwind, speed may have helped here, although the alternative route I took probably wasn’t a bad option (I crossed back tailwind and regained height no problem)
- A very tight landing that I took more liberty of the forgiving nature of my wing than I normally do. Only because I could, there were other options further back
- Day 8 Matterhorn
- I launched with a knot on a steep launch (thought landing elsewhere to fix it was a better option than trying to take off in the same spot). Does a two-liner have less lines to catch!??
- Scratchy to get established then booming. Amazing flying among high mountains
- Getting a climb, working weak lift, and a good glide were crucial to getting through the high pass by only metres
- My landing was in the lee but only because it was more convenient
Running with gear only half packed as I approached the evening time limit, also needed to launch efficiently without having to sort out lines
- Full speed bar in the sink and some spirals to get down in time
- Day 9 Mont Blanc
- Light conditions until the sun came out, then the best thermal of the race
- Some very unsavoury air which I was able to avoid by flying a relatively short distance away
- Glide and working weak conditions again an advantage
- On the home stretch to Annecy it was a good line and some extra speed may have given a marginal advantage
- A short delay to ensure a safe top landing, rather than landing badly, or landing elsewhere and having to walk. If the 2017 course has more top landings like this (which I hope they do) it will make the race interesting
- Another flight into the late evening. Classic cross country conditions
- Day 10 Ecrins
- Morning glide
- A frustrating struggle with the inversion. Ability to fly in choppy conditions close to the ground advantageous here
- Strong down valley wind on a crossing – helpful to have plenty of performance
- A long crossing where I arrived too low and had to get in deep to get out.
- A tight landing, but dropping it in the bush was more to do with fatigue and carelessness than anything else
- Day 11 Home stretch
- Classic, good conditions. Some pushing into the lee just because it’s more fun that way
- Very weak conditions later and a bit of huffing around on the ground ready to go
- A nice glide where you keep upgrading your landing paddock
In summary, it can be difficult to attribute success or failure to performance, but there is a few times where I felt it might have made a difference. I definitely credit this as an important factor behind my improved flying in recent years.
The biggest factor behind good flying is to make good decisions, and for that you need to have a good level of confidence. It’s important that you enjoy the experience and I’d like to say that the wing I fly for xalps would be the same wing that I’d take for a vol biv.
I have no reason to doubt that I’ll be confident with and love flying the zeno. But I have not had the personal experience to prove this point. I am relying on the fact that I will love it from the outset, in the same way that I started flying and went onto new wings in the past. The xalps has inadvertently become the testing ground for the new wing, where I can compare impressions with other pilots and we will all see what happens. Maybe distracting myself with a new toy will help me rein it in a bit for the first few days before I go out on my own.
thanks, it’s always nice to read your posts.
If you find the time, it would be nice if you could make a video (or show it as part of another adventure video) how you pack your glider. I noticed in one of your videos, that you dont use a concertina pack, instead you use the normal sack. Is it because you want to prevent wrinkles? Or because of better packing volume or because of the weight (concertina sack vs. normal sack)?
Also I would love to read more about your lee side flying experience. Things like, how you decide if it is possible to fly into the lee side, where to fly in the lee (close to the ridge in the upper part or outside in the valley?), how much wind can you accept, which lees you would avoid etc.
Hi Roman, I use my bivvy sack as a glider bag so I don’t have to carry both. I pack it the same way you would pack in a concertina bag – carefully, avoiding abrasion.
Thanks for your question about flying in the lee. I don’t know if I can answer it without going into depth and providing examples (maybe something for the book!). Of course every pilot needs to make their own judgements.
Thanks for your answers Nick! A book? That would be cool. I enjoyed the interview at the cloudbase mayhem podcast a lot and thought, that there are for sure a lot more stories to tell.
Good luck for the X-alps!
