3-28-05 Finally, this is Paragliding . I got my new glider in last week but didn't get the chance to use it until this past Friday for the first time. If you have any interest or know anything about gliders, here's a link to the glider's company web site: Pro-Design (Effect II) Well the weekend actually started on Friday morning when Alex decided it was finally time to go out flying. Conditions seemed to be on our side which means a good South wind to take off at the top of Mangshan (800 meters above sea level). Nobody was on site, as people obviously work during the weekdays. I skipped class and Alex's job is to fly, so it worked out for both of us. We took off and flew for a good hour. Sun was starting to heat up the ground but some rebellious thermals managed to stretch up as I flew about 300m above the take off site and Alex peaked at 1,500m (the height limit for the area since the airport isn't too far). Saturday and Sunday were good as well. About seven flights in total this weekend. |
Airfoil |
Flying is one of those things us humans can't really do in a natural way. We might not have gills or fins, but we can still survive on the surface of the water. We're not exactly predators on feet and our knees are possibly the worst design nature has ever come up with, but we can still walk and run around. Flying however, is the medium we can absolutely not conquer unless aided by something else, in this case a paraglider. What is paragliding? for those of you who aren't really sure, here's how it works in a nutshell. The paraglider, like any other flying machine, consists of a airfoil (see left diagram) shaped wing. A specific shape is given to the wing in order to divert the air in two directions: one flows above the wing (at a lower speed) and the other flows below the wing (at higher speed). As you can see the air going below by flowing faster creates upward pressure thus allowing the wind to fly. |
If you understand this simple concept, you just understood why birds, airplanes, helicopters, paragliders, hang gliders and sailplanes fly. The same concept applies to sail boats but I'm not getting into that. Every wing, has a minimum speed, which is the speed it needs in order to fly. As you can imagine, the minimum speed of a Boeing 747 is a lot higher than the one for a paraglider. This means the 747 has to rush up to about 250km/h in order to pick up flight. On the other hand, the paraglider needs about 10km/h. Does this mean you have to 'run' at 10km/h to take off on a paraglider from the ground and you will simply take off into the skies? No. Once the wing reaches it's minimum speed it is able to fly, but not go up. That's why airplanes have engines to maintain and increase the speed necessary to elevate itself. Unless you find any thermals (big bubbles of hot air that work as elevators in the air), a paraglider just 'glides' down at a certain rate (usually around 8meters horizontal per vertical meter). For this reason, paragliders usually take off from mountains. |

Bored yet? stick with me. Now, if there is absolutely NO wind, this means yo must run, pick up your glider into the air, and pull it up to it's minimal speed and at this point you can just glide off from the mountain. What happens if you have a 10km/h wind? well, the wind is running for you. All you have to do is pull up the glider and the wind speed will keep the glider in the air. That means all you have to do is take a few steps and the glider will start flying like a miracle. How does one stay up? if conditions aren't good, this means there's no wind, no thermals, and you can just smoothly glide down to your landing spot. Depending on how high you took off, the flight will last different amounts of time. This past weekend however, I was able to make a couple of two-hour flights, once on Friday and another on Sunday. |
Was I carrying an engine? again, no. Meteorology can become very complex and I am not the indicated person to explain you how all this works. But I have some vague idea which is how I manage to stay up in the air. Depending on the way the sun hits the ground or the wind hits certain types of surfaces, air is pushed upwards. If you find those spots, then you can climb up at speeds up to 10 meters per second! Thermals are the most common ones. Like I said before, heat on the ground causes big bubbles of hot air to form. After a while they detach from the ground and start floating up. Some only have a few meters in diameter and some can extend for a few kilometers. The thermals obviously can't be seen and this is where people become good at flying. One must feel when entering a thermal and circle inside of it to gain as much altitude as one wishes. Paragliders are highly maneuverable and can be controlled quite precisely as the pilot becomes more experienced. The fastest paragliders top up at around 65km/h and have a gliding rate of 9:1 (for every 9 meters it glides horizontally, it drops 1 meter vertically). |

What equipment is necessary? Paragliding, like any other activity, is very safe as long as you know what you're doing and never go beyond your own personal limits. However, weather is unpredictable and wing collapses do occur. For this, one should always fly with a spare parachute which is deployed manually in case it's impossible to recover from a collapse. What causes the wing to collapse? Turbulence in the air. Whenever you're sitting on a commercial jetliner and are told to buckle up when it gets a little bumpy (like it's really going to save your life), the plane is going through some turbulent air, many times inside clouds. While paragliding the same thing may occur, but because the paraglider is a non-rigid wing, it might just collapse. Helmet is always a must, gloves to keep you warm at high altitudes. A pair of sunglasses works well to keep the sun off your eyes. Depending on the type of flying, pilots like to carry a GPS and a Vario. The Vario indicates not only altitude but also whether you're going up or down at every moment, a not so obvious judgment as you are moving in a 3 dimensional space, something we're not really used to do. Finally, the paraglider is folded and packed and what you could call an 'oversized backpack'. They usually weigh in at around 20 kg including the harness and spare parachute. |
Well, to wrap this up, I'm just going to say that flying is absolutely amazing. There's nothing like it. This past Friday I was flying meters away from the World Champion, as I followed him into thermals learning how it's done. It just doesn't get any better than that. Paragliding is a safe sport and not extremely physical. I have seen teenagers fly all the way up to 70-year-old. The paraglider is a small investment and other than good care, it requires very little if no maintenance at all. No gasoline, oil or spark-plugs, you're just out there playing with the air and soaring with the birds. If you're in the Beijing area and are looking for something new, get in touch with me and I'll tell you how it works. If you're somewhere else around the world, look it up on the internet and believe me you wont regret it. Tandem flights usually vary in between 50-100USD depending on the country you're doing it. A price well worth paid to feel the experience.

3-24-05 I'm still here. So yea, it's been two weeks since my last update. Just haven't felt up for it and have little to say right now. Not really stressed but busy with lots of work, my head is somewhere else. So what's happened lately? I discovered I have the most atrocious allergy to cats. Sneezing, nose congestion and partial blindness are the symptoms. As a result, I look like a train had ran over me several times. Other than that, weather is finally changing as the next winter is only 7 months away. During the day, temperatures now reach 15 degrees C and at night it drops down to zero. Big problem now, are the sandstorms from Mongolia. At this time of year, they are typical. High winds, gusting up to 50km/h bring over sand clouds from the north and engulf the city. Next thing you know, you have sand in your shoes, in between your toes, in your teeth, in your nails, in your food, in your books, in your pant's pockets and needless to say your apartment starts looking like a sand dune. We had been waiting for March 20th to come around since it defined the date we could start flying again by the governments order. Well turns out the weather is beautiful to go out flying, but winds are too strong. So once again, no flying so far. On the good side of things, I got a paraglider and my bike is up for SALE. If you live in Beijing, China, or anywhere in the world (it can be shipped no problem), just let me know and we'll work something out. I'll have time to save up for another bike and make that long journey to Tibet this summer if everything goes as planned. 再见。 |
3-09-05 Walk slowly. I hate to say that "I'm busy" and have "no time" for something. I have always believed one makes time for whatever one thinks is important. Well recently I actually HAVE been very busy, but it's still not an excuse to stop posting updates. One reason is that they are part of my Comm 361 class and I must post blogs at least once or twice a week to earn credit. The second reason, is because I know out there in the world there are still some people that check out my web site when there is just nothing else to see on the internet while sitting at work. So yea, let this be your little break. |
So how is the title of this post related at all to this? Here's how it goes. 'Walk slowly' or in Mandarin 'Man zou' (慢走) is something we hear everyday around here. Whenever you walk out of a store the clerk might shout at you as you close the door behind you: "Man Zou!!". Then as you step off of the taxi cab after a nice conversation with the driver (of which you only understood about 60% depending on his Beijing accent), he might just shout as well: "Man Zou!!". So why walking slowly? In the West, I remember that if I was ever caught working too slowly or taking my time with things, I could be called lazy. Things are quite different in China, as doing things at their own pace is good for your health. I came to this realization (oh yea, my magazine editor is on my butt for writing theater and not theatre, meter and not meter, organization and not organisation, those British!): these past couple of days I've been running here and there, up and down, a cab here another there, pictures here and even more there. Work is due for my classes in the US, I have to go to class, work on some other business, eat, going to the gym (yes I never thought the day would come but I decided that I want to be healthy), and finally but most important of all, simply Have Fun! That's what life is all about in the end, fulfilling your responsibilities but in the end laughing, smiling and just having plain fun. Well surprisingly I've been able to do all of these things in 7 days a week (only skipped a few classes). I started getting all stressed about about things, oh geez I have to do this! but then when am I going to do that!! does it leave me with enough time to go there? You know what??? just take a breath, and walk slowly. Whether it is standing in line at the bank, sitting in traffic or waiting for your fries to come out with the Big Mac Meal, just think that working yourself up is only gonna make it worse. Do like the guy in the picture above and take it easy. This 'walking slowly' is present in many facets of Chinese. Things might unfortunately start changing with young people and more influences from the West, but for now, many still employ it. Relax, slow down, eat something and get things done. I tried it and it's working so far. Have a good one today! |
3-03-05 Fights on the street . I don't think I've ever written anything on this subject but it is well worth to talk about it at least a little. Since I've been here, I have seen probably around a dozen fights on the street. These do not include drunk lads getting all raucous at clubs and bars. I am talking about fist fights in the middle of a major street intersection with thousands of bystanders standing around watching a man beating a woman as if it was the WWE. Yesterday I was walking around the Wudaokou market with my editor and two Koreans as she was doing an article on Korean Fashion. I was there to take pictures of the whole thing. At the entrance of the mall we notice a man literally strangling a woman as he held her by the neck while her skin turned red and her eyes rolled back in desperation. People screaming others just watching the dispute, the small battle kept going on until the "Baoan" (protector of tranquility from chinese, see picture on the right) came up and split up the struggle. |
| In the meantime, I stood there, with my camera in hands, shooting one picture after another. I've heard a foreigner should NEVER get involved in a fight between Chinese people. One reason is because it's simply not our problem and we shouldn't really try to play the superhero role; secondly, because they are 1.3 billion against two! (you, and the person you are trying to defend). Anyways, after the brawl was over, I went into the mall with my editor and the two Korean girls. All of a sudden, a little circle of chinese people surrounded me trying to snatch my camera away and asked me if I had taken any pictures. I looked at them in confusion as if I didn't understand what they were saying and discretely got lost in the crowd of the mall. So let that be a lesson when taking pictures of bad things happening around here. None of them are published. |
