ORANGE WEEK 2012, The Week That Was

January 2012 saw the return of Orange Week to the Waikerie skies. Under the directorship of John Hudson the twelve pilots sought to maximise their flying fun with some even electing to add spice to their tasks by risking “Fresh” class. Some wont do that again.

Overall winner and recipient of the “Orange Week” trophy was Craig Vinall, or at least the AS G29E proved its worth. Some handicaps may need to be changed for next year. Well done and well deserved.

The Maurie Bradney trophy for the most meritorious competitor was collected by Grant Hudson, though it seemed to be a case of who was the last left standing after all others had upset the scorers. Again, a well deserved award.

ORANGE WEEK 2012/2013, YOU’D BE A FOOL TO MISS IT.

Orange Week Day 4 Winner’s Recollections

Friday 6/1/12

Orange Week Day 4 – Winner Grant Hudson, LS4a

After the trials of flying dry in fresh class the day before, Craig and I went straight back to Juicing Class for day 4 and I elected to fly wet, adding 50 litres of water to the LS4. The task was back to basics with WGC – Peebinga – Lindsay River – WGC set as an AST. Heating was a little slower than expected due to cirrus moving across the task area so we were all surprised when dad, while taking a passenger in the Duo Discus, reported 4 knots at 3000’. I was at the front of the grid so saddled up and launched into what proved to be a rather soft sky. By the time the start gate was open thermals were going to 4000’. I made a start with Pete Paine and David Jones just in front and lined up a row of red / ploughed paddocks that roughly stretch SE from Waikerie all the way to Pata with small deviations required to stay over them. Cores were small but strong and difficult to fit into. About 15km short of Peebinga I’d had enough and dumped all my water. It had been a hard slog down to Peebinga with no feeling of certainty of getting a climb but the track seemed to be working as I’d pulled clear of Pete and Jonesy.

After turning Peebinga the day seemed to click for me…dry was definitely easier today. I simply ran from red paddock to red paddock up the border working a 2000’ – 5000’ height band. Every time I needed a climb it seemed to be there and I felt happy with the rhythm I was now in. Abeam Taldra I diverted west to stay in the sunshine as the cirrus had moved in further and thickened up a bit (a look at Painey’s trace later showed he did the same thing) and I had the best climb of the day with 2km to run into Lindsay River with an average of 4 knots to nearly 6000’.

In and out of Lindsay River and I diverted to 2 tractors working paddocks just north of track with no worthwhile result and then a slow glide straight to Renmark aerodrome arriving there at 1800’ giving enough height to conduct a search for a thermal that I found right above runway 07. I then headed out over the scrub for a while before collecting a climb to final glide at the paddocks on the northern edge of Lake Bonney. With the light winds I thought the river valley would be working so jumped on board just near Banrock Station and weaved my way up the valley towards Waikerie hitting extended patches of lift of 6 – 8 knots. This enabled me to get faster and faster on the glide for the first time in a week with no nail biting going on at all and I had a great run to the finish line at 140 knots and finished with a straight in on the 26 grass pad in front of the pie cart.

Considering the conditions I was pretty happy with 81 kph off the stick but sat in the glider for a minute or so with my legs dangling as it had been a hard day. I was even happier later when Ridgey told me I had won the day as it was my first day-win in any comp I’ve flown!

Stats for the day: 34 thermals @ average thermal strength 2.9 knots, average glide = 10km.

Can’t wait for Orange Week next year.

Orange Week Day 3 – Winners’ Recollections

Winner of Juicing Class – Andrew Horton, Mosquito

The arrangement Colin and I came up with when we got the Mozzie is that each one of us would crew for the other, whatever comp we went to.  We’ve just come back from the Junior’s at Kingaroy (which was a saga in itself) so it was my turn to fly it, somewhere locally.  The SA comp had already started by the time we returned, so that was out… which left Orange Week at Waikerie.  I hadn’t been to an Orange Week comp here before, and I was told it was a fun event, with everyone competing for something other than sheep stations (just oranges, as it turned out).  It would follow on from Coaching Week, which itself was a success.

Day 1 was a stinker of a day, or alternatively a ripper, depending on how you look at it.  Basically a free-for-all, to cover as much distance as one could, in whatever time was available, and hopefully to make the track look like a triangle, which would maximise points.  Not used to this concept, I decided to make a mess of the day, and did out-&-returns in various directions from Waikerie, but such as to make fitting any sort of triangle to the result nearly impossible, with the result that I came last.

Day 2 didn’t happen.  Canned due to lousy weather.

Day 3.  Forecast to be slightly better, so a task was set.  I duly got the Mozzie out, then towed it to the launch point.  Or rather, tried to.  An undercarriage failure on tow-out put me out of the day, and would require all of the day to repair.  Not too many tried the task that day anyway.

Day 4.  This was THE day.  Good conditions, so Meribah (with a 20k circle) – Maggea (20k) – Taldra (30k) was set, to be completed in 3 hours or more.  For some reason, as it subsequently transpired, I came first!  So, how did I go from a predictable last on one day to first a little time later on?

Couldn’t have been the weather – we all flew through the same weather.  Couldn’t have been the terrain either – we all flew over the same kind of ground.  I know – it must’ve been the successful repairs to the wheel hub the previous day!   So, if you want to win a day, just fix the undercarriage.  Simple.

OK, for those who don’t believe that ridiculous excuse, I’ll have to try a different tack.  All I did, really, was to stick as far as possible to a track over red paddocks (which everyone tells me are better than other parts of the countryside for generating lift), or scrub (just as good), or edges of scrub, or even edges of scrub which are adjacent to red paddocks.  Most of these worked.  Perhaps not worrying about getting low helped too – after all, I had a crew, and the trailer was ready for retrievals; all I needed to do was to phone my GPS co-ordinates to the crew, and they’d do the rest.  Google Maps and an iPhone GPS-based navigation app would help greatly.  So, no worries there, leaving me free to fly the glider.

There was an inversion to start with, at 5000ft, and by the end of the day this had gone up to 7000ft.  This meant that there’d be lots of thermals, so the chances of running in to another thermal before getting low were good.  So, no worries there either.

The rest is history, and I managed to get back nicely, subsequently registering a good speed around the task.  But I’ve noticed that the Mozzie also seems to like weaker conditions too.  Oh, and going dry helped a lot too.

Actually, I’d like to stick with the broken-hub theory – it sounds nicely absurd.

Winner of Fresh Class – Craig Vinall, AS G29E

Today, Grant, Allen and I entered into Fresh class, which gives the task setters the right to add some twists to the daily task. In our case, we flew the AAT set for Juicing class, but the last turn point was a 500m radius circle instead of the 30km that the others had, and there was an exclusion zone of 20 km radius around Cobdogla, which is between Kingston and Barmera (not on turn-point list).

The day was a little better than the previous day with climbs to around 5000ft. The task was to Meribah, then to Maggea and finally Taldra.

The subtlety of the exclusion zone soon became apparent in that it had to be avoided on each of the legs. And given the strong southerly, this made it more difficult as I planned to fly just to the south of it on each occasion. Most inconvenient when needing a climb on the southern edge of the zone; I kept being blown into it!

There were good climbs towards Meribah, but like yesterday, they weakened the further east I went. The run back to Maggea was good, but then the task took me over the river north of Loxton. It was totally quiet over the river and irrigation, and I did not get a good climb until well east of the river. The only problem was that had to be my return track and the same thing happened again.

So as I reached my target to avoid the exclusion zone (10km north of Wunkar) I needed a climb but was hindered by the possibility of drifting into the zone. I pushed on and then took a climb when I was sure that I was clear of the exclusion zone and then head back to Waikerie.

An interesting twist to the task.

Orange Week Day 2 – Winner’s Recollections

Day 2 (Wednesday 4th January), Winner – Craig Vinall, AS G29E

After the great weather of Monday, Tuesday was cancelled due to mid-level cloud and cooler conditions.

Wednesday presented us with strong southerlies and cooler conditions. The day was forecast to be soarable, but with maximum heights of 5000ft. An AAT task was set of 2.5 hrs from Waikerie to Pata (20km radius), to Morgan (45deg sector) and Maggea (15km radius).

We started launches at 12.30 and were achieving 4000ft so an early start was in order. Conditions to Wunkar were very promising, good pull ups and easy centring of good thermals. But towards Pata the conditions started to weaken and after turning to Morgan, did not improve until past Wunkar again. Conditions remained reasonable to Morgan but with thermals that seemed to be broken.

Turning into wind from Morgan, I only need to touch the Maggea circle and towards the last turn point, I struggled to get final glide. I dumped my water in an attempt to get a better climb rate for what I hoped would be my last thermal but struggled to find a decent climb. Every time I turned, I was being blown away from the turn point. Very frustrating.

Finally I got a climb and headed back to Waikerie, glad to be assured of reaching the airfield for a speed of 91kph and a distance of 264km. A somewhat difficult day.

Orange Week Day 1 – Winner’s recollections

Day 1(Monday 2nd January), Winner – Craig Vinall, AS G29E

The weather forecast was for a strong day over the western ranges. It looked like a classic trough day and sure enough the cu’s stated popping around noon.

My plan was to fly to the clouds just north of the airspace step at Eudunda (12500ft) and then fly north along the trough line as far as possible before turning south again along the trough line.

The clouds were extending out towards Waikerie with cloud base at approximately 10,000ft. But it was difficult to get a strong climb all the way to cloud base, so I approached my first turn at Eudunda at about 7000ft. It wasn’t until just short of Burra that I eventually got a strong consistent climb that took me all the way to cloud base which was now at 12,000ft.

I had picked a track that was on the eastern edge of the line of cloud in the trough which was heading in a north-westerly track.

It was great flying north and then again south; very little turning and maintaining a height band of between 10,000 and 13,000ft. I made my northern turn at Wilmington, the furthest north I’ve ever been. I had to turn there anyway as I was about to fly of the edge of my map!

The wind had been north-westerly, so I was now flying down wind. It was quick and I averaged 169kph for this leg even though the thermal strengths were in the range of 5-6kt average.

I tracked again over Burra and deviated slightly to avoid the airspace step then tracked for Lameroo. 30km short of Lameroo, the clouds were not providing any lift. A large area of ground was in shadow, so I turned towards Peebinga into some sunshine. The conditions were weakening so I decided to dump my water. I got to the edge of the cloud where the sun was still hitting the ground, but the air was very rough with broken thermals. I was 4000ft below final glide and 120km from Waikerie, so I decided to take a weak thermal to final glide height and then head off. But the conditions back to Waikerie were very buoyant. I suspect that it was the expected southerly change and that was responsible for the turbulent conditions I had experienced.

I was able to fly back to Waikerie at speed and landed only 25 mins prior to the competition cut-off time of 8pm. I landed into the east with light winds, but as I was towing the glider back to the hangar, the southerly wind change hit the airfield. It was very gusty so I suspect my flight back was on a sea breeze front.

Flight distance was 790km at a speed of 131kph (per OLC-Plus), the longest (undeclared) flight I have done to date.
