Day 10
The cold front that was forecast for the day moved faster than expected dumping an incredible amount of rain on the area in the wee hours of the morning.
The day dawned with sky filled with broken cumulus, much like all the rest. The drift was a little more easterly than usual.
On launch the sky looked good. The wind was coming up the back side though, that is the side of Pico de Ibituruna that faces away from the city. They call it the south launch although it really faces ESE.
The south launch is somewhat problematic. It is essentially a cliff launch with a short, flat, grassy area to layout the gliders on. The lip of the cliff is sharp enough that when gliders are laid out they are in a null zone. So even when the wind is blowing at a reasonalbe speed you have to pull it up through this null zone into the breeze. This makes for exciting and easily blown launches. Added to the mix is that there is really only enough room between the cliff edge and the staging area for one glider so the time interval between launches is increased.
A short 54.7 km task was called with the last turnpoint being Pico de Ibituruna and the goal at Feira de Paz, the LZ next to the city.
Being post frontal the day was unstable. Fallout and overdevelopment along the course line forced a change in the task before the window was open.
The modified task was an out and back in the opposite direction. Again finishing with a turnpoint on the top of the mountain and goal at the main LZ. The out and back was 54.6 km.
Despite the potential for problems on the south launch all the competitors were launched within about 15 minutes. Well, all but one. One woman pilot got stymied as clouds engulfed the hill before she could launch. After a 30 minute wait she was able to get off though.
Meanwhile, as the pilots moved towards the start cylinder, conditions looked reasonable. A cloud street developed heading nearly straight to the turnpoint. So by the start opening it looked as if they would have a good task.
Back on the mountain however, overdevelopment upwind was threatening to bring rain and a possible gust front. I launched after all of the competitors had cleared the area and advanced towards the first turnpoint.
The lift was good but the fallout upwind looked a bit ominous and after 15 minutes of soaring the south side cloudbase began to lower again. So I ran towards the city and the leeside. There was lift in the lee but it was quite turbulent. And the wind in the Rio Doce river valley began to increase, undoubtably a manifistation of the squall on the other side of the mountain. I landed in a 15-20 km/hr breeze as the sky above the mountain became overcast when the overdeveloped clouds smeared downwind.
It still looked good on course line but it looked like it would be difficult for the pilots to complete the task.
And they didn’t. The early word is that most dropped out near the first turnpoint. It is unlikely to be a high scoring day so the standings shouldn’t change much after the scores are tabulated.
Big party tonight. Awards tomorrow.
Results will be posted on www.2005worlds.com as soon as they are posted here so you can check there and find out the final results quicker than I could type them.
10 tasks.
Gobs and gobs of airtime.
Thousands of 360’s.
A few injuries but no significant accidents.
A pretty cool competition.
Oh yeah, it was the World Championships.
