Day FOUR

Another hot day with high possibility of rain/thunderstorms.
Organizers trying to mitigate risk and avoid situation from couple days ago when some pilots waited in the air for storms to pass and teams on the ground got soaked to underwear (our crew included).

for today:

Results from all days available  here


We will try to post few pictures this evening.

Dave's Day 3

Today, I was beaten by the weather man.  Now, let me explain that statement.  At the morning briefing and on the weather briefing sheets that were handed out, the weather man said there would be 100% cirrus cloud cover over Leszno by 4 pm.  A short 2:15 task was set for our class to get us home before the day shut down.

Unfortunately, the weather man was wrong and as of 8 pm, there are still no cirrus clouds over Leszno.  Because of the expected short day, I started with another group at 1345, and we had a slow run in weak thermals and low cloud base (about 3000 AGL) for the first and second legs.  Most other pilots must have had better weather information as the majority of the class started an hour after our group in significantly better weather.

The problem with setting short tasks like 2 hrs is that it lets people wait that extra hour or more and fly in better conditions and really is no test of pilot skill, but of team composition and which team has the best weather man.  This is really frustrating for us who don't live on this continent and don't have access to good weather sites, or can't read the language on the local sites.  Well, that's enough complaining!  Hopefully, the weather man will improve his forecasting.

As you can see by the barograph trace, things improved significantly after 3 pm, in part due to being later in the day, but also because the first and second legs ran through the area where a lot of rain fell during yesterdays thunderstorms.


 On the route map below, you can see the large deviation that I made on the third leg.  This was again because of the large blue hole from the yesterday's rain.  The path that I followed was quite good with a really nice cloud street that ran about 1/3 of the leg north.  I was then able to connect to another shorter street and then some isolated clouds before turning almost 90 degrees across the blue to enter the third area.  From there, it was a turn back towards the clouds in the east  for the fourth area where I was able to connect with a good climb that put me on final glide back across about a 30 km hole.


Day THREE

The weather yesterday was quite challenging with showers and thunderstorms passing around.
Our team returned before major storm, some other pilots waited in the air until they can come back home. Today's situation looks similar, so far no sign of rain. Very hot and humid.

Orginizer posted the follwing tasks:

Dave's Day 2

Day 2 was another challenging day and I had another slow day.  There were rain showers scattered throughout the task area, but had the largest impact at the second turn area, and then on the last leg home.  I had to fly through some heavy rain about 25 km from Leszno on the final glide.  About 15 minutes after I landed, it started to pour at the airport and some pilots had to wait out the storm before they could finish and land.

During the flight, I kept seeing the same gaggle, so I thought I was doing OK, but it seems they all picked up 10 extra km in a couple of the turn areas and that made the difference.

I am trying to analyze my flight against some of the other flights to see where I made mistakes, but I am having trouble seeing material differences in some of the statistics.  The only thing that really stands out for today was I flew and extra 11% distance above the task distance and the other flights were 4 and 5 %, so on a 380 km task, that makes about an additional 20 km of unnecessary distance.

Below is my flight trace combined with two other traces.  My trace is the red one. From this, I see that I flew the same route as the blue, but green drove really deep into the second turn area.  This is where we ran into our first wall of rain today.  Just before the rain, I had a great 7 kt climb to 6000 ft and then was able to run the shelf of the rain front into the turn area.  The green guy decided to take it further, but then had to deviate a long way west on the way out.  However - he won the day.  Probably based on that extra distance.


The barograph trace shows that I used about the same working band as the other two pilots.


So the goal for tomorrow is to try and deviate less, but on a day with rain in some quadrants and blue holes in others, it seemed reasonable to make the deviations at the time!

Day TWO

Today we have similar weather condition as yesterday. 
Overall very hot day influenced by southern air mass. 

Grid time 11:45.

There's real time tracking page for limited number of competitors where you can see progress.
