Swiss League Cup 15.-16.3.

Weather informations

Martin Scheel, 14. March 2014
What a Desaster to find a decision :-(... I try to explain the weather forecasts: Saturday ********** We will have lots of clouds in the morning. But all models show a sunny window from 10 - 15 hour at the north side of the alps. Maybe check http://meteo.search.ch/cloud. If we have bad luck, a sort of "Lenti" will remain fix at any position. Probably not... The frontal clouds arrive in the afternoon first with high (7000m), then middle layer (5000m). At the same time cold air will arrive. The stability will dissolve and strong valley wind will dominate. - Wind at 2000m 14 hour about 10-15kn W to NW. - Later and higher the wind is much stronger If you check the thermal prognosis BEO you see, that the thermal top just arrives in a hight with wind. Ths could be the case at Grindelwald, Verbier. Cloud base / thermal top 2200m - max 2500m (probably lower) Pressure gradient rises from 5hp at noon to 10hp in the evening... Sunday ********* After the frontal system we will have some "Restwolken". They should disappear, especially at the west side of the swiss alps. But we will have very strong wind above 2500m (30kn). Probably we will have a light inversion at cloud base. Together with a small Subsidence and Warmluftadvektion, the clouds should dry out. It can be, that the conditions below that layer are Ok for flying. Where to go??? ***************** Verbier: Only local flights, because of clouds, wind, valley wind... Wallis, Tessin: Northwind (the snow will strengthen the downwinds) Kandersteg Difficult with low cloud base and strong velley wind. Grindelwald Would be one of the possibilities. Maybe it works for take off, flights to Burg and back would be possible. Meiringen Windy, local flying possible Adelboden Local flying possible, but Westerly in altitude and valley winds in lower level... Decision ********* After many phone calls with the locals, we decide to cancel the Swiss League Cup and make Regio-Flights at Interlaken and Verbier.

New rules in CIVL and PWCA

Martin Scheel, 4. March 2014
CIVL News for 2014 ********************** During the plenary meeting, held on Feb 2014 following changes have been defined: CIVL Competition Class CCC: A new Competition Class has been defined from a CIVL working group in a huge effort during the hole last year under the leadership of Jörg Ewald. This CCC has been supported by EHPU and PMA. It passed unanimously during the CIVL plenary meeting. The requirements in short: Use full EN certification (EN 926-1 and EN 926-2) as the basis. Additionally: - restrict top speed at 65 km/h by limiting the maximum accelerator effect - restrict aspect ratio to the maximum flat aspect ratio exhibited by EN certified gliders by December 31st, 2013: 7.9 - require riser sets which prevent pilots from exceeding the certified top speed - require models to be available in multiple sizes: Smallest size < 100 kg, minimum weight range must be >25kg (from 1.1.16: < 90kg / >35kg) - require flight tests to be conducted at the top of a wing’s weight range only, using a competition harness where relevant, flown from factory pilots if necessary - set the waiting time until pilot input for collapse tests to 3 seconds - add clear, precise and simple-to-follow measurements and testing procedures. The manual has to contain all relevant measurements. Revision may be proposed in one year. At all times, if needed, CIVL Bureau has the power to adjust the requirements. Glider controls: During the next European championships glider controls will be carried out. Guidelines will be published on what to measure, how and with what tolerances. These will be in accordance with CCC measurements and tolerances. CIVL will send someone to do the measurement, on CIVL budget. Different news: - European Championships 1016 will be in Macedonia. See Swiss Glider ?? - Helmets: new standards are allowed (coming from snow sports). - Penalties for violation of airspace rules are re-defined: “Where the pilot's track log is recorded closer than 20m from prohibited airspace, vertically or horizontally, a penalty of 2% of the pilot's task score per meter shall be deducted, resulting in a zero 30m within the restricted zone.” - All rules for scoring Category 1 events are now included in new document called "CIVL GAP 2014". - GPS distance and altitude measurements are redefined, altitude correction with “true altitude” implemented. This will not be used to check for airspace infringements. - Continental WPRSs will be implemented. In European championships, the qualification criteria will refer to the top 400 of the European WPRS. PWCA News ************** There are two major new rules: 1) Disccards on all World Cups Great News, we can fly easier and faster. 2) Conical end of speed section It is complicated to understand it exactly, but in fact we need to know only two parameters: a) Optimum speed (just a position on the riser which should be delivered from the manufacturer according to the polar) b) Minimum lift to stay in the thermal In fact, the CESS does reduce the problem of cheating with speed in final glide. For the pilot it means, that he has to fly more r less like during the hole task: Search for good lines, optimize speed according to lift and sink. In Swiss tasks (including Swiss Open and Disentis Open), we will use CESS occasionally to learn about it.
