1000km flights

[[email protected]]

On 30 December 2017, there were 34 flights of over 1000km posted onto the OLC. These were all in Namibia and South Africa. What is the record number of +1000km flights done in a single day? I would imagine there could have been more flights done because not everyone posts their flights on OLC.

There is another thread from 2015 called "Africa!".
On November 30th 2015, there were 40 flights posted on OLC with distances exceeding 1000km.

Call a 1000K task on a good day at a Nephi contest and you will have 65 1000k's in a day.

Jonathan: Actually, no you won't. 1000 km requires 7.6 hours of flying at 130 kph (the average speed of the 30 folks who did it in Africa on 12/30). You can't launch 65 gliders,open a start gate, and get around a 1000 km course on a contest day other than at a strong ridge site on a great day. On 1000 km days in Africa we start really early and we fly really late. Go to OLC for 12/30 and look at how long some of those guys were flying. Markus Frank was close to 10 hours. 10 hours at 133 kph!

I still think New Castle, VA has the record for 1000 K's in one day at one site, something like 17? This is like 20 years ago or so, covered a couple times in Soaring magazine (the day and then a reunion). Some even flew it dry, sorta Iron Man a dry stiff winger. Regardless, a long flight, even in good conditions.
My longest glider flight is "only" 7 hours. Done on thermals in the NE US.

[Tony[_5_]]

They'd have to be able to launch the grid in under an hour to be able to do that

[Jonathan St. Cloud]

My comment was tongue in cheek. I was thinking of New Castle and what a great call by the CD that was!!! I have attended a Nephi event and I launch was very efficient, I thought after a few days all 65 glider were launched in an hour. On a 17,500 foot day, tasks of 3 or 4 hours do not do Nephi justice.

I think the 2005? Open Europeans in Rayskala Finland had a 1000 k
task with about 17 finishers - all thermal of course! :-) .

[Charlie M. (UH & 002 owner/pilot)]

Not all contestants were happy with that call.
Yes, I have flown there before.
No, I was not at that contest.

Still, a remarkable achievement from one site on one day.
Wish I was there, not sure I would have completed it.....

I remember when they called the first diamond distance length task at the open national in minden. It was on the longest daylight day of the year, I think it was 1977 or 78. All I remember is the triangle sent them way out to Austin NV. My bro was one of the few 15 meter ships flying that contest and made it home (zuni). I was glad since I was the crew and them zuni wings were heavy lol.

[Tom BravoMike]

I remember Sebastian Kawa expressing himself in one of the interviews against extremely long tasks. A competition is more about a comparison between pilots, and not necessarily about endurance or chasing for records or 1000 km diplomas. It has to do with safety, as too long tasks over several days inevitably bring exhaustion with them, and possibly accidents.

I see all the sailplanes doing the long flights in Namibia are either self-launching or fitted with sustainers. I imagine the logistics of getting trailers and crews to Namibia, as well as flying over pretty isolated areas, must make flying there in a conventional sailplane pretty daunting.

They don't have a towplane.

Most of the Namibian sites have self launchers that are shipped down in containers. No towplanes there. Most South African sites used by visitors have tow planes - but many gliders in SA also come down by container without trailers. Usually these are turbo sustainer types - though there is an occasional self launcher. Local SA gliders are usually pure gliders except for a few Jonkers gliders that have jet sustainers.

Here is a link to a photo essay I wrote about the containers. It was submitted to Free Flight but was never published. ROY

No, of course not! I can't recall his achievements in glider aerobatics or his altitude records. However, as far as soaring contests are concerned, he has not left the position #1 or 2 for 12 (twelve) successive years in the IGC world ranking list, which probably reflects, to some extent, IMHO, how experienced a competition pilot he is. Please see the table at the bottom of this site:

http://rankingdata.fai.org/SGP_displaypilotdets.php?pilotid=491

[[email protected]]

But I can recall his achievements in long-distance flights in Namibia since 2007 in the OLC. No single one!
I have seen only 3 flights over 1.000 km from Sebastian in this time and these flights were flown in Argentina, in wave condition, in a double-seater with an experienced pilot in the rear seat!

How can he say: "...long tasks over several days inevitably bring exhaustion with them and possibly accidents..."?

Every year hundreds of pilots make thousands of long distance flights in Namibia, flying day by day and the accident rate is close to zero (no single one this year!).

I´m flying there since 1999 and the few accidents I have seen have been caused by unadapted speed in high altitudes (one), by a down-burst during landing in Bitterwasser after a thunderstorm and nearly all he others be physical unadapted people, collapsing in the hot African summer short on the first day after arrival, with jet-lag in their bones. No one by "exhaustion after several long tasks"!

I made 131 thermal-flights over 1.000km and more only since 2007 and I´m also flying several competitions every year. Believe me, the accident rate in competition is much, much higher.

No doubt, Sebastian Kawa is one of the worlds best pilots. But his favorite discipline is competition and not every good "sprinter" in our sport is also a "marathon runner"!

Three years ago, we have had the same discussion in "Soaring cafe" (http://soaringcafe.com/2014/12/wishing-happy-healthy-safe-2015/) and it is interesting, that mainly people, which are not really competent in long-distance flying are ascribing a lack of safety to our kind of gliding! Why?

I think Sebastian Kawa was referring to the combination of 1000km flights and racing. The African camps (I have not flown in Namibia but have flown from Gariep in South Africa) are very relaxed and laid back. Most gliders are self-launchers or at least fitted with sustainers so long retrieves are not an issue. Everybody assists everybody and pilots set their own tasks according to their mood/attitude/experience for the day. Pilots think nothing of taking days-off and experiencing the wildlife or just relaxing by the pool between flying days. Competitions are a bit different - it's a far more stressful environment. Now combine 1000km tasks into the competitive racing environment - and Sebastian is then correct when he states its a recipe for accidents.

[[email protected]]

I always thought that physical and mental endurance was a key factor that nationals and Worlds are meant to test? I thought that is exactly what the longer contests are for. Flights of 5 plus hours were common along with a hell of a lot more long days/nights making retreaves. I think the written words of Moffat, Johnson, Butler, Gimmey, and good ole Wally Scott would back me up on this point.

If tests of mental and physical endurance are not a major factor of what contests are all about, and the trend to midigate all the "risk" factors continues, then why not just eliminate the ships all together, set up the contest scenarios on simulators with 3 hour MAT's and see who wins. Geesh, what has happened to our sport.

[[email protected]]

Exactly! 1.000km in competition is another thing than flying long-range in Africa/Namibia! Thank you for clarification!

That's exactly what Sebastian was referring to: the competition flying. My remark was a reaction to Jonathan's opinion that 'On a 17,500 foot day, tasks of 3 or 4 hours do not do Nephi justice.' And he is probably right in this specific case, but generally, the golden mean has to be found between number and length of the tasks flown in an area with consistently excellent conditions.
The interview I had is mind can be watched here (for Sebastian's opinion in question please start at 14:00):

Thanks for posting that Kawa interview. Competition dynamics has definitely changed since the days of Moffat and Reichman. Kawa would be considered a pussy if he had to race here during the late 70's lol. Its apparent he prefers short and fast tasks. Those type tasks may play to his particular skill set. In my opinion, that only "tests" one aspect of cross country competative flying. Another aspect is the ability to make critical decisions over an extended period of time and interaction with changing wx conditions along course. Those two aspects only start to come out during longer tasks as well as multiple days of longer tasks.

A decision needs to be made whether competition soaring is meant to be a test of "sprinting" ability or a test of "marathon" ability. Hopefully it will be somewhere in between, but lets not jettison the "marathon" aspects (both mentally and physically) of competative soaring.

Are you aware of Kawa's 'non -competitive' exploratory flights - in
the Himalaya and Caucauses and other parts of the world ? i.e.

Well, he mentions 500-600 km as his estimate for the upper limit. I wouldn't call that 'a short' or 'sprint' task. They are still a diamond worth...

[Tony[_5_]]

He seemed to do just fine in Uvalde 2012 which did not feature short tasks...

He's also evidently rather good at flying large gliders over and around
very big mountains, as my club found out when he visited last year. He
spent some time in Nepal flying an ASH-25 in the Himalayas from Pokara.
Amongst other things, this included following the Kali Gandaki river
through the mountains to Jomoson, on the Tibetan side the range, and back
again. Thats an out and return of just under 200km and almost of it
unlandable. The Kali Gandaki is the deepest river valley in the world. It
runs between Daulagiri (26,800 ft) and Annapurna I (26,500 ft) with the
river at around 8,500 ft where it passes between the peaks.

We are talking about glider *racing*. The maximum difference between emphasis on "sprinting" and a "marathoning" in FAI (non-GP) glider racing is around a factor of 2. In atheletics it is from 10 seconds to around 2.5 hours and requires entirely different athletes. It is laughable to argue, simply because his experience indicates to him that oversetting task lengths leads to poorer *racing", that the man who is undoubtedly the most prepared, determined and obsessively competitive glider racer to have appeared would fail if the tasks were a bit longer .

It would be interesting to see today's pilots in action without electronics devices. I think that S.Kawa advantage would be even greater ;-)

You put ten pilots into a contest involving 7 or more consecutive days of 4+ hour tasks, and throw in a land out or two, and you see it requires a much different skill set ( both mentally and physically) than what we have today.

As for longer distance tasks, its a function of increased performance . A 250 mile task set in the 70's-80's is equivalent to a 320 mile task in todays machines.

All I am saying is todays racing is a much different style of competition than the last generations. Todays contests "test" a different skill set. But to say that multiple "long" tasks are "dangerous" and we better keep things shorter for safety sake, is to me, actually defining modern racing. This sentiment goes along with disallowing low high speed finishes, and the preference for tasks with variability in turnpoint penetration/selection.

All these changes have changed racing. Is it better than the "old days"? Not necessarily. Is is worse than the old days? Not necessarily. Is it safer than the old days? Possibly, but is safety what racing is about? Not necessarily. Racing is racing, and safety when all the rules have been emplaced, is still a matter of personal responsibility. Don't tell me that a guy flying a machine with a sustainer doesn't take more chances in a race than a guy flying a conventional machine. Is he safe doing it? Not necessarily.

Hurculean advancements in performance, electronics, and changes in competition pilot mindsets have changed the sport. Which direction it ultimately goes is still up in the air, along with its survival.

Many of us have already read this article by Karol Staryszak. An important contribution to the discussion about the 'racing-safety' relationship:

Hi Tom, thanks for that post. I had read it before but it's been awhile and this one I feel is good to re-read yearly specially before a contest or a personal goal flight.

[Charlie M. (UH & 002 owner/pilot)]

Excellent and sad.
Excellent on the points and point of view.
Sad in the reason for the writeup and knowing (personally) people that have been hurt.......or worse while flying.

Thank you for the link.

Correct, that was the one and only 1000K task in EGC/WGC level competition. Briefing was announced to be early in the morning and I think they were launching right after 10. Some 15m class pilots were furious because they got only 850K task.

[[email protected]]

If tasks were set to the maximum every day then Sebastian would win by more, based on my observation of him relative to other pilots over the last four WGC and a couple of GPs.
Here in Australia we have an ageing pilot group, (like USA) and a rash of accidents in the over 75 group unfortunately.

6 January 2018 - another huge day for 1000km flights. I am seeing 41 on OLC so far. Some may still be added by pilots who only get online later and there are perhaps some too done by pilots who are not on OLC. More of a mix of venues - with the longest distances for the day being flown from Potchefstroom in South Africa - the home of Jonker Sailplanes.

Uys Jonker's 1250km FAI triangle at 157km/h - new world record? Looks like they were trying to show what the JS3 is really capable of

[[email protected]]

Trying? 4 X 1250km triangles. All 15m.

[[email protected]]

They were actually flying 18m - and looks like all 4 could have broken the previous 1250km record

In 1983 I called a 509.36 mile task for 24 Open Class pilots, 18 completed and 5 landed within the area.
Went to Ravendale, Mill City, Austin and return as I remember. Flying my 1000K from Parowan on June 19, took off at 10:20 and landed at 7:20.

A record is "broken" if it´s ratified by the FAI!

The only one with a "proper" flight declaration in his flight-recorder is Oscar Goudrian!

We will see, who is sending his "Preliminary Notifcation" to the FAI...

In September last year, Attie and Uys Jonker presented the SAIMechE John Orr Lecture at the University of the Wi****ersrand. They spoke about the dream of building the best glider in the world, the development of the JS1 and then the development of the JS3 and getting it to Australia in time for the World Champs a year ago. The lecture was recorded and is still available to view at the following link: http://tinyurl.com/johnorr2017

It's well worth watching. The first hour or so is Uys talking about the JS1 and the second hour is Professor Attie talking about the design of the JS3, and the leaps they have made in utilising computational fluid dynamics in the design. The attention to detail in the development is incredible and goes a long way in understanding why the JS3 is performing the way it is. The audience was predominantly Mechanical Engineers who sat enthralled for the entire 2 hours.

That was brilliant, thanks for posting Clint.

Pleasure. Even my non-engineer/non-glider pilot wife enjoyed the talk - just their knowledge and passion is so engaging.
