Stunning... just stunning! Good post-processing, too. Now, imagine at the same moment that Robi and Mirko are gliding at ~3.0, a flock of mattresses falls from the sky in the camera view... at typical f10cking glide ratios ~1.0. That'd be an eye opener. See... there's no need for war between performance flyers and f10ckers... they can work together on the same project!

Wingsuit Studio has been updated with the new version of World BASE Race module. The new version includes Optimizer which automatically finds the fastest flying mode for given L/D. If you have already played with WBR module, you may have been wondering, "Well, what would be the fastest flying mode out there? what wingsuit, what kind of performance would result in absolutely fastest time?" Optimizer uses brutal force approach and tries all possible modes to find the best. It turns out, the higher L/D, the better the time. So to be realistic, Optimizer uses L/D you set as a maximum L/D that it will not exceed while searching for faster finish times. For given L/D, there exists an optimal flight mode (i.e. combination of sustained horizontal Vxs and vertical Vys speeds) that results in fastest time possible while satisfying the constraints (terrain + minimum pull altitude). Here are the results (with minimum pull altitude of 300ft (~90m) and zero launch speed): L/D Best Time (s) Vxs/Vys (mph) 1.5 26.02 81.1/54.1 2.0 21.43 110.9/55.5 2.5 19.99 123.1/49.3 2.75 19.68 121.1/44.1 3.0 19.19 129.9/43.4 Some obvious conclusions from the results: - tracking suits are out: no competition to wingsuits, several seconds behind - WBR *is* mostly a L/D competition. Awesome! Anti-Marl'09, anti-mattress, anti-trackingderby all the way... as it should be to begin with. Schweet L/D, baby! A good test for different makes of wingsuits (besides, of course, being a test for different pilots). Wingsuit manufacturers, here's a good show to shine on! - shortest finish times demand very fast (yet high L/D) flight modes. Heavier pilots with high wingloading (while maintaining L/D in 2.5-3.0 range) will have advantage over the light pilots. - strong launch always helps (assuming pilot is capable of doing it without compromising efficient flying and safety). 5mph (~2m/s) launch speed results in about 0.3s shorter time. - the fastest flight mode is that just skims the terrain about half-way to the finish line and just clears the minimum pull altitude. Note that this means "naturally" high L/D mode, not just diving down with average L/D intentionally and skimming the terrain and pulling low. Again, heavy jumpers with efficient L/D will have advantage, as after natural curve pullout they will be lower - but faster - than lighter jumpers. - the spread between L/D of 2.5 and 3.0 is quite small, less than a second. Therefore, not only excellent flying skills, but ability to do a strong launch precisely at the starting gun matters a lot. Pilots with running/ski/swimming competition experience will have advantage over good pilots who never jumped by starting gun. - moving WBR to a bigger mountain where the spread between the best pilots will be less "electronic" would be a better test of pilot's skills and wingsuit rating. The flight modes calculated by Optimizer are at sea level, standard temperature (15 C). Use Flight Mode Converter from Tools menu to convert it to a different altitude. Typically, at 6000ft speeds are about 10-12% higher.

Actually, sustained glide ratio is slightly higher than L/D, because as you're flying into continuously denser air, you're constantly moving at slightly higher speed than true sustained speed for current layer, so effectively, you're constantly plane out. The effect is tiny, about 1%: if you enter, for example, Vxs=100mph, Vys=40mph (L/D=2.5) in Wingsuit Equations module in Wingsuit Studio, you will see that sustained glide ratio is about 2.53. That's nothing compared to secret method of bumping G.R. by 40% discovered by Tony in Marl.

Introducing Wingsuit Studio, a revolutionary -- see, I do nothing but revolutionary stuff -- wingsuit flight analysis and modeling program. Wingsuit Studio is expandable with custom "modules" designed to do specific task. They are based on Wingsuit Studio's framework which is centered around numerical Wingsuit Equations solver, Flight Library which allows you manage pilots, flight modes, and mountains, and Unit Library that handles unit conversions. The software development kit will be coming in the near future allowing programmers write their own modules. Currently, 3 modules are included with the installation: Wingsuit Equations Shows derivation of Wingsuit Equations and solves them numerically. Wingsuit Equations are differential equations of motion governing wingsuit flight dynamics in two dimensions. Simple and beautiful, they allow for high precision simulation of wingsuit flight by knowing sustained velocity alone. This module shows the derivation of Wingsuit Equations and explores various aspects of wingsuit flight: trajectory, velocity, acceleration, glide ratio, and other properties of the flight. To solve WSE numerically, the 4th-order Runge-Kutta method with integration step of 0.1s is used. Solving WSE is handled by Wingsuit.Equations.dll .NET class library which you can freely use for your own Wingsuit Studio modules and other projects. L/D Calculator Calculates average L/D from BASE jump distance, height and time using Wingsuit Equations. L/D Calculator is the most consistent and accurate way of estimating your L/D from a BASE jump. To use it, you need to measure distance, height, and time by using GPS or by wearing a video camera and passing close to a topographic feature which you can measure on topo maps. Note that the flight must be straight, no turns. L/D Calculator samples various flight modes (flight mode is a combination of horizontal and vertical sustained speeds) and solves Wingsuit Equations for the duration of your flight (in assumption of constant flight mode) until it finds a mode that results in the closest match with the actual distance and altitude used on your jump. L/D Calculator first uses "Hill Climbing" method of finding the solution, with a random seed between 0 and 150mph or 250km/h on the velocity grid. The step is gradually reduced until an accurate enough solution is found. This is a fast method, but sometimes it fails to find the best fit. If this happens, brutal force method is used which samples every node on the velocity grid and gradually reduces the step until satisfactory match is found. Note that L/D Calculator normalizes sustained speeds to sea level and standard temperature. Exit altitude and exit temperature have virtually no effect on the calculated L/D, but they do affect sustained speed. If your launch is very strong, estimate your launch speed and use it in calculation, as it affects calculated L/D. The old technique of estimating L/D by subtracting some altitude used to start to fly from the available altitude and dividing the distance by this altitude gives inconsistent results, as the higher or the lower the mountain, the lower or the higher the contribution from the 'starting to fly' portion of the flight would be. Using L/D Calculator for flights of various degree of performance and in different wingsuits allows you to build polar curves (collections of flight modes) which can be used in other modules. World BASE Race Helps you choose optimal flight mode for flying the World BASE Race (Romsdalen, Norway) in shortest time possible. While there is no substitute for experience to win the World BASE Race in Romsdalen, Norway, the different modes of flying are too many to explore in limited time, and this is where World BASE Race module comes to help. This is a tool that helps you answer questions like these: - Do I need the highest L/D suit to win? - Is it better to do a steep dive to get more speed, or to start flying as soon as possible? - Is large, floaty suit or small, speedy suit better for the purpose? - Will losing or gaining weight (or using extra weights) help me shorten the time? - Do I stand any chance in a fast tracking suit? The module uses Wingsuit Equations to simulate flights of two pilots based on their flight modes. If this module does help you win the World BASE Race, send me a case of your favorite beer! ;-) Also, Wingsuit Studio includes several sample pilots. Pilot is a collection of flight modes, and flight mode is a combination of sustained horizontal and vertical speeds normalized to sea level and normal temperature that characterizes wingsuit flight dynamics for specific pilot in specific suit at certain body position and angle of attack. These sample pilots will get you started, and you create your own pilots based on GPS data of your flights. Pilot files can easily be exchanged between users and imported into the Studio.

Jeez, Spot, not only you are the D/L King, but the Drama Queen as well! Thus, representing a complete Royal family all by yourself. You will make the wingsuit world better by doing nothing. What's happening now with all this "Tonysuits-F**ckU" tsunami of shit is purely disgusting.

Comparing distance or speed results from different times (Robi's is year old) without knowing the winds and flight direction at the time of flight does not make any sense. Android+Wear/iOS/Windows apps: L/D Vario, Smart Altimeter, Rockdrop Pro, Wingsuit FAP iOS only: L/D Magic Windows only: WS Studio

What were the winds doing and what was the direction of competition run relative to the wind? Now with all these trackingderbyish* competitions out there, the word "performance" starts losing any sense. Huge mattresses start beating suits known for their high L/D - in DISTANCE challenge, no less! And here's a quick example of possible why. Suit 1 - speed & glide demon. Vx = 105mph, Vy = 40mph, L/D = 2.625. vs. Suit 2 - slow, but decently performing mattress. Vx = 75mph, Vy = 30mph, L/D = 2.5. Over 1000m of altitude in 30mph tailwind: Suit 1: time = 55.9s, distance = 3375m, glide ratio = 3.375 ((105mph+30mph)/40mph) Suit 2: time = 74.6s, distance = 3500m, glide ratio = 3.5 ((75mph+30mph)/30mph) Slow mattress "trackingderbied" the higher performance suit. It's like a giant 7-cell accuracy canopy will outfly a higher L/D crossbrace in strong tailwind because it will take advantage of the push for significantly longer time. How 'bout doing two runs in the opposite directions and averaging the results? With this setup, the wind effects will be minimized. But then again, people just love setting up nonsensical competitions of all sorts, so why would they? Yuri ------------------------------------------------ * like in, "You're so trackingderbyish!

It doesn't take Ph.D. to realize that with this definition, any random blob of f1ocking meat bodies can be called a formation. Take: - no requirement of fixed grid size - no requirement of filling all adjacent cells - way too loose requirement that "some part of the Wingsuit flier must be visible inside a line delineating their space" and you can resize and shift the grid until all randomly distributed bodies fit in it. The success of the effort to fit the definition of record retroactively to a failed attempt of one is nothing but remarkable!

Watched Fly the Line 2 several times already. And every time I'm thinking, "Such a quality of flying will be hard to beat for a long time." Just outstanding. This is true flying that sometimes seems to be endless. The level of performance clearly seen in this movie - L/D in 3.0 whereabouts - makes not a mere incremental improvement over what we've seen in the past, but an eye-opening qualitative breakthrough. Exits are smooth and precise, and angle of attack is nailed in the first few seconds. The planeouts are almost unreal, with glide ratios of 4-5 for 10-15 seconds making footage look like it was taken from a hangglider. The clever helmet mount with a very wide, yet almost distortion-free lens looking back accentuates the distance traveled and quickly makes the mountain become a small part of the landscape. The smoke trails are just awesomly tight, clearly demonstrating the quality of airflow (compare to smoke trails of f10ckers). The flight lines are like lines carved by a sculptor - precise, often even scary, nothing can demonstrate the skill and performance more. When I want to show to someone what mountain flying is, the is the DVD I will play. Simply breathtaking! Oh, and the last, but not least: f10cking sucks!

Agree. That's what flocking should be in the first place! (f20cking vs. f10cking) Only slightly bent limbs - virtually unnoticeable, tight flock with no oscillations, narrow smoke trails. Pleasure to watch. Kudos. Perhaps, organizers of gazillion-ways, photogs with hyperinflated egos, and brainless f10cking meat from the other side of the pond should come to you euro boys to learn the basics.

Tony & Spot, You nailed it - the giant burble behind a big air mattress is identical to a burble behind windshield of motorcycle or convertible, which makes hats and smoke fly forward. But while with motorcycle or convertible this necessary comes with the ride, with wingsuit it's a totally unnecessary shame. Or, in D/L terms, a Pride. Why would several very experienced jumpers not only fall in the same poor flying regime when all of them have a huge range above it, but also use smoke to emphasize this extremely poor aerodynamics - is beyond my understanding. But, as a director of D/L Hall of Fame, I welcome new honorees regardless of their reasons. 3.06... quite an "improvement" in "performance", eh? 20mph at altitude with a limp windsock is nothing. It's not uncommon to have 40-60mph at altitude with nil winds on the ground. I know you are a very good flyer, but numbers, unless they are extracted from BASE data or from a balloon jump with wind profile measured with GPS during the climb to altitude, mean nothing. That's why one year in Stupino the stars of wingsuit world flew at less then 2.0, while the next year some jumpers never heard of before flew at 3.0+. Because that next year everybody knew the forecast about strong wind day and waited for it. Yuri P.S. Spot, if you want to be The King again, you have to do something truly spectacular, D/L-wise.

Spot, I'm sorry to inform you that... that... that you lost your honorable title of the King. That Shuttle mattressing is surely No.1 now for the long time. A perfection of technology, amazing achievement of human kind, on one hand, an The Three Kings In Mattresses, on the other. What an epic FAIL! More sadly, that these pictures and videos will be published in magazines and presented to general public as the image of human flying.
