August 2020 - a Great Summer in Kyushu

The COVID pandemic prevented us from traveling to Europe this year, so we made the best of it in our home area of Kyushu, Japan.  Far from being 'small', clearly, this is a place worth visiting by any XC pilot, with great route potential and first-rate scenery!

Here is a brief summary of my flights.

August 20th - a 40 km FAI triangle by tandem, before overdevelopment set in.

The track along the nortwest part of the outer Aso caldera.

Tandem happiness!

It's Tandemonium in Aso 😊

Better Together

Mt. Aso at its greenest.

August 19th - Yet another 100 km FAI

Once again taking advantage of conditions very similar to the previous flights.  This time, taking off and returning to Kabuto-iwa instead of Daikanbo, and making Futae-toge the first (westernmost) turnpoint.  I did this because the convergences were predicted to shift farther west than before, and the did, and it worked!

Today's Kuju

Lucky smoke showing convergence, not far from the eastern edge of the caldera.


Mt. Aso

August 18th
Not too bad. 40km triangle in fairly light (stable) conditions.  Very similar to the tandem flight a few days later.  When clouds did not pop up, it was too stable for a really big fight.

Leanne scratches for what she's worth in weak conditions along the caldera. 

XC in Aso at its best.

Aso scenery

Happy slope landings

August 17th - 108 km FAI, probably a Japan record. Less lift than the day before, some scratching to add interest.

Great forecast!

祖母山  The Sobo Range; this summer was the first time I flew this far!

August 16th  100 km FAI
ayvri video:

Takeoff: Daikanbo, Aso
Turnpoints: First Zogahana and back to Daikanbo, because it's hard to come back to Daikanbo in the evening.  Then, AUTOPOLIS racecourse in the NW, past the Kuju range in the  NE, and the Sobo Range in the SE.  Between Kuju and Sobo, and Sobo back to Aso, one rides the main convergence that forms in the afternoon on good days where the sea breezes meet over the center of Kyushu island.

涌蓋山まで行った  Mt. Waita, turned out to be an uncesessary detour and I nearly got derailed by large patches of sink.

最後は火事  A fire while scratching at the end of the day.  In spite of trying to use it for lift, I couldn't quite close the course, coming up less than 400m short

August 15th

Today's XC (37km) turned out to be preparation for the three 100km triangles that followed.  Without clouds, it was too stable to sustain flight over the plateaus.

Mt. Aso

Aug 14th -  A 35 km trek in the Central Kyushu Mountains
Relief from the summer heat can be found in the remote Central Mountains, with their highest peak, Mt. Kunimi, at 1738m.  Once the punishing climb from the deep valley is over, the trails along the ridgetops go up-and-down only slightly, making for easy walking among great scenery and a remoteness that are suprisingly atypical for Japan.

Aug. 12-13  Iriki, Kagoshima Prefecture
This little area is actually well worth a visit, with great scenery, XC potential, and a touch of the subtropical southern atmosphere.  It has been revived recently by local fliers who are encouraging visitors to come an fly, free of charge!
An out-and return flight (about 25km) to the coastal Satsuma-Sendai city and back.  The area's location near the west coast.   Only 35km to the NE is the prime XC launch Uono, from where it is possible to cross clear to the other side of Kyushu.  The right conditions may be a bit difficult to come by, but a record-breaking Kyushu crossing flight is possible from here!

Iriki is located on a small extinct volcano, complete with a crater lake.  Beyond is the route toward Uono...
