What's New

Dream Building by Tom Wolf

Here is the story of a 12 year pursuit of a dream -
building your own powered glider. Tom Wolf - one of our new students -
describes his building of the ultralight powered glider
"Cumulus" (plus trailer) that is nearing completion.
Hats off for his perseverence and best wishes for the completion! 
And of course, will it get close to its hoped for 1-26 performance?

The Twin Astair is back on the line

Great news, as of this Saturday, the Twin Astir is back on the line and available to be flown. Let the soaring season begin...

The 2016 SSA Convention

Some impressions from the recent SSA convention in Greensville SC by Ed Walker.


White Chuck Mountain: Portal to the Cascades

After years of having the “why don't you come out and enjoy the mountains” conversation with numerous glider pilots, some who have been soaring for years without venturing into the Cascades, and some who are relatively new to soaring, I think I have unraveled at least part of the puzzle. It's a four letter word that begins with the letter “F”. You know the one: Fear. Yes, that old bugaboo.

The OLC 2016 - An Intermediate Report

While we have just started the calendar year 2016 and are still awaiting the first signs of usable lift (ridge, wave or thermals), it is hard to believe that the OLC year 2016 is already mostly over for the southern hemisphere (having started on September 20).  The conditions in southern Africa (i. e.

Beyond Jordan Ridge

Just in time for the coming season, here is the personal account of one of our newly minted mountain pilots. As a reminder, the Evergreen Soaring club has Flying Rules in the by-laws that specify XC qualifications and separately mountain soaring qualifications. While these are required for pilots flying as PIC in club gliders, they are also highly recommended for flying in private gliders

Cross-country Soaring with Club Sailplanes

XC (cross-country) soaring – generally defined as getting out of gliding range and thus the comfort zone of the home airfield – has been the mission statement of the Evergreen Soaring Club for some time.  And the results of the Willy Burhen Cup bear out the attraction of this kind of soaring for a dedicated group of pilots.  Closer inspection of these results, however, shows that this relatively small group consists almost exclusively of private owners who were intrigued enough to invest the money to acquire their own sailplanes and have the time and drive to go XC.  There is

The Willy Burhen Cup (WBC 2015) and the Joe Patton Milestone

September 21 was the last day of the OLC year 2015 and it is time again to review the various soaring achievements of the past season.  This was the 11th year for the WBC, a simple decentralized contest for the best XC flights on the west side of the Cascades as evaluated by the OLC.  So here is a list of the 17 pilots who posted their best XC flights of over 100 points

Green Valley Airfield Familiarization

Anybody contemplating XC soaring has to be prepared for the possibility “that the wind dies” and that a return to the home base becomes impossible (even for a powered glider which may not start up).  Landing at another airfield is the preferred solution to this predicament but making an off-field landing may be the only option.  So far this year four Evergreen pilots had to make off-field landings while venturing from Arlington, showing that this is not a lost art.  All these landings were executed without any problems, demonstrating that off-field landings on the west side are not as chancy or risky as sometimes assumed.

June 13, 2015 - Quite a Day

May and June show typically the best thermal conditions in Washington and together with some of the longest daylight hours present the best potential for extended soaring flights. Saturday June 13 of this year saw a number of ambitious XC pilots attempting some really long distance flights. The OLC provides a good look at what happened and allows some useful statistical comparisons. So here are the best flights from our different airports in the state:

The Twisp OLC Camp

The very successful Twisp encampment is now memory and it is time to relate some of the experiences and to sort out the relevant achievements.

First and foremost, it was successful because of Ron Clark thoroughly organizing this event, getting the Twisp community involved (including an article in the Methow Valley News), and getting a lot of local businesses to contribute prizes.

And the whole event would not have been possible without Duane Barr's tireless towing efforts (and having to wait until every pilot was back for a possible retrieve before having a beer). 

The 2015 Region 8 Soaring Championships

Once again the Region 8 championships, taking place from June 14 to 20 in Ephrata, was a popular gathering for competition pilots from near and far.  32 pilots participated in 5 classes and enjoyed conditions ranging from tough to perfect. 

The 2015 Evergreen encampment in Ephrata

by Zach Schrempp

Every year, the Evergreen Soaring club goes on a weeklong encampment to the Ephrata Airport, located in central Washington. Ephrata usually has strong thermals and high cloudbases, giving club pilots a chance to soar for long periods and try cross country flights.

Reflections on XC Flying

Memorial Day saw the now traditional Dust Up fun contest at Ephrata which was also the begin of the Evergreen Soaring encampment this year.  This provided the opportunity for novice and experienced pilots alike to enjoy the thermal conditions and the wide open spaces of Eastern Washington.  Following are the observations and reflections of our youngest XC pilo, who is incidentally now also preparing for the Region 8 contest.

OLC and Skylines Differences

For 12 years now the soaring flight evaluation program Onlinecontest or OLC has become the worldwide standard for evaluation of flight performance providing almost instant insight into what is happening in the world of XC soaring. It went thru a number of changes and updates but is now officially endorsed by the International Gliding Committee (IGC) and has been a tremendous instigator of getting pilots to push their XC soaring skills.

A Different State of Mind

by Ron Clark

I like Oregon. Always have. I was born there, and brought up on the south coast in the logging and fishing town of Coos Bay.


Of course I can visit by car or any other conveyance, but since I like to fly gliders, visiting the home state in my favorite method of transport, the UN-motorized glider, has always been a goal.

The AERO 2015 Exhibition

The annual AERO Exhibition for General Aviation in Friedrichshafen took place in the middle of April 2015 and this year (as every second year now) it included the full glider segment.  Almost all major manufacturers for sailplanes, accessories and engines showed up and presented their latest offerings.  There were few new sailplane designs but a lot of refinements and developments.  Most notable was the eagerness of most manufacturers to offer some sort of electrical propulsion either as sustainer or self-launching application.  At the same time, jet engines are also off

The 2015 Willy Burhen Cup

As usual, the XC season for Evergreen Soaring started in March; however it did not really start in earnest this year until the beginning of April. We had a number of days with exciting soaring conditions that combined strong lift with showers and overdevelopments,that required shifting between survival flying and racing. 

Green Mountain to Mount Baker

By Ron Clark

Friday March 27th was a good wave day for our part of the country.  On the way to the airport I got a good look at the amazing lenticular cloud hovering over Mt. Pilchuck that Dan Housler had told me about earlier on the phone.

Beginning of the 2015 XC Season

Saturday February 21 started with a lot of low lying clouds but by noon the sun had cleared the skies over Arlington and some cumulus clouds were forming in the mountains to the northeast. 

The Outlook for 2015

Now that the year 2014 has is history, it is time again to look at the state of the Evergreen Soaring club.  We have still fewer tows than several years ago and our XC flying has decreased considerably.  We had to cope with particularly rainy weather in spring, the Oso landslide TFR and the unavailability of towing or instruction at times.   Let’s call 2014 a year of consolidation and work on increasing our activities again.

Noteworthy Flights From Arlington in 2014

Now that the Willy Burhen Cup (WBC) 2014 is history and serious XC soaring has to wait for next spring, it is a good time to reflect on how this past season went and what one can learn from it.  It turned out to be another contest between Dan Housler and Ron Clark.  Both pilots had won the WBC before and both had previously made cross-Cascade flights.

The 2014 Willy Burhen Cup (WBC 2014)

Now that the official OLC year 2014 is over it is time again to review again all the XC soaring flying in Western Washington this year. After a slow beginning due to very wet weather the soaring season started in earnest.

Arlington Airport Appreciation Day 2014

For the 2014 Arlington Airport Appreciation Day on September 20, Evergreen Soaring displayed the G-103 Twin Astir and explained the basics and finer points of soaring with the visitors. Local families who attended told us about watching Evergreen gliders fly over their neighborhoods heading toward the AWO landing pattern, and were eager to see one up close. Many children, and a few adults, were able to sit in the cockpit and get a view from the pilot’s perspective. We also had three walk-up demo rides. Appreciation Days is a useful public relations opportunity for Evergreen Soaring.

Mount Ditney or How to Get Away from Arlington

One of the reservations that some pilots have about going XC from Arlington concerns the difficulty of connecting with lift and getting sufficient altitude to get going.  This is especially true in late summer when the flat lands around Arlington and even the foothills further east offer only marginal lift and altitudes that make even staying up a chore.  These conditions look even less inviting when there are no clouds to indicate any convection (which happens quite often).  What is not apparent in these cases (even with Dr. Jack’s predictions) is the fact that the higher mountains, starting some 15 to 20 miles further east  from Arlington, quite often offer great thermal conditions.

Traversing the North Cascades

While most of the Evergreen members were tryng to make a favorable impression on Sunday August 23 about our flight operations on our guests from the Soaring Safety Foundaton (Tony Condon and Adam Kite) or enduring a gruelling 4 hour board meeting, Ron Clark and Brad Hill took long tows into the Cascades to make another exploration of the North Cascades. Ron Clark made yet again a noteworthy flight with 414 OLC points (best in Region 8 for the day) and agreed to provide the following report. Just don't believe it is as easy as Ron descibes it!

So here is Ron's report:

Twisp Expedition

After a soarable spring and early summer, mellow and, unfortunately, stable weather takes over the Puget Sound. In attempt to break away from it, four pilots - Ron Clark, Brad Hill, Bill Ling and Movses Babayan, moved to Twisp for a few days for a chance to experience some of the stellar soaring conditions that Methow Valley has to offer. Phil Anderson has graciously provided towing in 17Z.

50 km Distance from Arlington

Some 90 years ago the Silver Badge was created as recognition of outstanding soaring achievement (1000 m altitude gain, 5 hours duration and 50 km distance).  Soaring progressed rapidly and so the Gold Badge, the various diamonds and then the 1000 km diplomas and so forth were created to keep up with the possible achievements.  And the Silver Badge became pretty much the entry level requirement for any self respecting soaring pilot, who is serious about XC soaring.

The 2014 Evergreen Encampment in Concrete

The annual Arlington Fly-In in July with its busy traffic, air show restrictions and tower operations has become the stimulus for an Evergreen excursion to one of the nearby mountain airfields (Darrington or Concrete).  This year the destination was Concrete over the July 12/ 13 weekend.  Concrete had not been visited for a few years by Evergreen and – most of all - it has now a fuel pump, eliminating having to transport fuel.

2014 Region 8 Contest

From June 8 to 14 the SGC hosted again the Region 8 contest for this year in Ephrata. Ron Bellamy (as contest director) and a whole crew of veteran contest workers made sure that the contest was run efficiently, safely and in a friendly spirit.

Of Bovines and Brave Pilots

A lot has been said and speculated about the best preparations for XC soaring preparedness - two-seat XC, buddy flying with more experienced pilots, simulator training, planned landings in grass airfields and so on. One key ingredient is of course being prepared to make off-field landings "when the wind dies" and there is no convenient airfield in reach.

Status of WBC 2014 (as of May 5th, 2014)

After a wet February and the wettest March on record, April of this year gave us finally some more soaring-friendly weather, making for a slow beginning of this year's XC season on the west side. Best days so far were April 26 and 28 with Dan Housler and Ron Clark posting the highest scoring OLC flights yet of about 450 points.

Coping With the Oso TFR

On March 21 a historic land slide devastated a little community east of Oso, about 15 miles from Arlington airport. And since March 23 a "temporary" flight restriction zone (TFR) with a radius of 8 nm and up to 6000 ft has been in effect.

Soaring Mount Everest continued

As a follow-up to the 2/10/2014 article in eGlidepath, some more information has become available.

The 2014 SSA Convention

The annual SSA convention in Reno (Feb. 27 to Mar. 2) was well attended, including by a large contingent of Northwest pilots. It was a time to find out what is new and get motivated for the coming season. As usual there were a lot of interesting talks and interesting contacts, even if there was not too much technical news.

So here are some personal impressions:

First Soaring Flight over Mount Everest

On January 31 Klaus Ohlmann succeeded in making the first soaring flight over Mount Everest, another achievement for this outstanding pilot.  According to the first sketchy reports, he took off from the Pokhara airport in Nepal in a Stemme S-10 motorglider, climbed under power high enough to continue in soaring flight toward Mount Everest.  <--break->Using weak thermals and ridge lift and then rotor and finally wave lift he was able to climb over Mount Everest (29,093 ft). 

Handicap Systems

Since the advent of modern composite sailplanes with ever increasing sophistication and performance pilots with yesteryear’s types have tried to equalize the achieved performances in competition or record flying with the help of handicapping systems.  And ever since such handicapping systems were devised pilots have argued about the fairness of such systems.  The goal is of course to emphasize pilot

The 2013 SGC Awards

November 2 saw the annual awards banquet of the Seattle Glider Council (SGC), as usual for some time now at Ivar’s Salmon House at Lake Union.  In addition to a social gathering at the end of the season this was the time to recognize special efforts and special performances during the past year in the greater SGC area (which sometimes extends to beyond Washington state.).

2013 Update of Joe Patton Milestone

Since 2005 Evergreen Soaring recognizes (and encourages) upcoming club XC pilots by listing the first reasonably documented soaring flight that includes a straight line distance of at least 50 km in Western Washington. This is in recognition of the memory of Joe Patton who very much encouraged such flying and who left us much too early.

Shunpike and Storefronts Auburn are pleased to present the newest installation at One Main!

Public artist Jim Pridgeon worked with frequent collaborators Benton Shaw and Richard Beckerman, as well as volunteers from Evergreen Soaring (Evergreensoaring.com) to install a Czechoslovakian designed and built Blanik L-13 glider into a raw ground level space at One Main Street Professional Plaza, a nod to Auburn’s history as an aviation town.

The 2013 Willy Burhen Cup

The 2013 OLC year ended officially on Monday October 14, 2013 and with that the WBC 2013 has also been decided. So here are the results - a list of the best flights for each pilot from Western Washington. Most of the flights started at Arlington (Evergreen's home base) but two flights originated in Bergseth (home of PSSA).

Soaring in the Himalayas

For over a dozen years the MWP (Mountain Wave Project) team, consisting of top sailplane pilots and meteorologists has been mostly associated with the exploration of the awesome wave systems created by the Andes.  Exploration of these unique weather conditions has resulted in many spectacular soaring world records, including the longest and highest soaring flights ever.  Now the MWP team is trying to explore the Himalayas.

Bye, Bye Blanik

With the sale of Evergreen’s last L-13 Blanik – N 2414J – the era of the Blanik seems to have come to an end, for Evergreen and probably the US.  While 14J is supposed to continue its career as an exhibition model in Auburn (hopefully providing some advertising for soaring and Evergreen) no L-13 has flown in the US since 2010, when a mid-air breakup in Austria grounded the L-13 worldwide. 

Region 8 Competition in 2013

The WBC 2013

Halfway thru the soaring season it is time again to look at our yard stick for west side XC soaring - the Willy Burhen Cup (WBC 2013).  This little friendly competition amongst west side soaring pilots is now in its 10th year and still gaining momentum.  It is based on the best west side soaring flight of any pilot according to the OLC rules and has proved to be quite a stimulus for exploring the challenging XC potential of Western Washington. So here are the results for the WBC 2013 as of July 15. 

Student Progression at Evergreen Soaring

One of the standard questions for any newcomer to the Evergreen Soaring Club (ES) is; “How much time and effort does it take to become a glider pilot?”  Our old web site gave some optimistic information like “15 to 20 flights to solo” and “another 20 to 30 to license.”  Experience has shown that this information was somewhat misleading and we have seen quite a few new members leave the club before getting a license or even before getting to solo.  There are undoubtedly many reasons for this but one is certainly that it takes considerably more time and effort (not to mention m

May 14 - A Day to Remember

There were all the ingredients of a big day – a good weather prediction from Dan Housler, an eager group of ES pilots finally hoping for a great XC day, an impressive early line-up and start of towing just after 11 am.  Phil Andersen did the towing honors and one by one all hopeful pilots disappeared apart from one that sunk out (guess who).  Clouds were still trying to develop over the low lands while the mountains were full of low clouds but conditions gradually improved.  Most pilots were able to fly later in the mountains getting to over 7000 ft.  It turned into a lo

The Schleicher ASG-32 – Competition for the Schempp-Hirth Arcus

The just concluded AERO 2013 tradeshow in Friedrichshafen/ GE was the official unveiling of the ASG-32 by Schleicher.  This is a new 20m two-seater with flaps that is obviously Schleicher’s response to Schempp-Hirth’s (S-H) highly successful Arcus.  It has not even been flown yet but offers some insight into the latest thinking of modern racing sailplanes.  It will be built with an engine compartment as standard equipment and will be offered with the same retractable rotary engine unit as most of the other Schleicher types.  A future electric sustainer is also in the works. 

West Side Triangles

The increasing popularity of the OLC has led to an increasing element of competition for XC soaring with an ever-increasing world wide participation.  It also has led to a competitive drive to get the most OLC points for a given flight and before 2011, when the points were determined by simple distance (discounted for the 4th and 5th legs), this gave rise to the preponderance of “Yo-Yo” flights, i. e.

Spring has Sprung - Finally

March is usually the month when thermal deprived Evergreen soaring pilots look for the first days of recognizable thermals to allow getting away from the confines of the AWO pattern.  This year it started with Ron Clark and Chris Young posting the first tentative XC flights (with over 100 OLC points) on March 4.  Things got moving on March 18, when 3 pilots were able to speed up to the border and back in three hours.  Things got more exciting on March 23 when improving conditions allowed flights of up to 5.5 hours into the mountains and 6 Evergreen pilots posted flights on the OLC.  Ron Clark took the top spot with 404 OLC points; he together with Dan Housler and Brad Hill did not only get the top spots in Region 8 on that day but also in the USA!  And Movses had his first go at this in the L-33 and posted actually two 100+ points flights – not a bad start.
