Self launch effect on soaring growth

As more self launch sailplanes are built, what will
be the effect on soaring growth?

Will soaring clubs decline? Will self launchers disperse
to many more airports, creating more exposure?

Any thoughts?

I've been a glider pilot in the USA for almost 30 years, with the last
10 years spent flying a self-launching sailplane (SLS). Until recently,
there seemed to be two types of pilots that bought self-launching
sailplanes like the DG 400, PIK 20 E, ASH 26 E, etc:

Type 1: long time (20-30 year), very experienced cross-country glider
pilots looking for more convenience

Type 2: power pilots wanting to be glider pilots but put off by the
hassles of towed gliders; that is, also looking for convenience in the
use of the glider (but perhaps not so interested in serious
cross-country flying right away).

For type 1 pilots, having an SLS seems to keep them in the sport, and
generally still involved in the activities and clubs in the region, at
least in my region (northwest USA).

For the type 2 pilot, the SLS brought them into the sport.

So, for these two types, the effect of the SLS on clubs and soaring
seems beneficial.

Recently, the availability of moderate cost, moderate performance
gliders like the Russia AC-5M, Apis, and Silent, has attracted a third
type of pilot:

Type 3: medium time (a few years) glider pilots that also want
convenience, and perhaps especially an entry into cross-country flying
without the retrieve worries.

I know very few of the type 3 pilot, so I'm not sure how much they (as a
group) interact with clubs and other pilots once they have their glider.
I suspect it's much like the type 1 pilot: if they were active in a club
before, they will continue to be active.

Most of the pilots I know like to be around other glider pilots, and I
don't see SLS pilots dispersing to airports where there aren't other
gliders.

My conclusion: self-launchers are a benefit to the clubs and the sport.

Although I'm a purist, I agree with Eric that the effect overall is
beneficial for soaring. However, if you buy used first and second
generation equipment, you will likely spend an equal or greater time
maintaining your equipment to a high standard than actually soaring.

It's about a 50/50 split between self-launching pilots I've met that can
soar effectively and have no clue.

YMMV,

Assuming this means PIK 20 E and DG 400 gliders, it's not what I've
observed. The people I know, and know of, with these types of gliders
spend a lot more time soaring than maintaining. There will be increased
maintenance as the gliders accumulate engine hours, of course, but
nothing approaching the 100-200 hours/year these pilots fly. There may
be a year with particularly high maintenance (engine rebuild, say), but
that's followed by years of lower maintenance.

Regardless, the amount of maintenance of a self-launcher is still much
more than an unpowered glider. A sustainer powered glider will be more
like the unpowered glider than the self-launcher, as it's engine hours
tend to be 2-3 hours/year, compared to the 10 or so for a self-launcher,
and it's systems are less complicated.


It's about a 50/50 split between self-launching pilots I've met that can

Getting these less skilled (in soaring) pilots up to speed can be a
challenge, because the independence of the self-launcher tends to keep
them outside the "support system" that can teach them to soar.

I'd put myself in this Type 3 category. I've got 300+ hours in
gliders and a few really good cross country flights, but all
spread over many years. If I feel I can spare the money,
or find the right partners to share it, I might some day get
a motorglider so that I could fly cross country on those
less than perfect days that I avoid now to avoid the hassle
of a retrieve.

I can't speak for anyone else, but if I got a motorglider,
I'd plan to stay in our club. The reasons are 1) I value
the ongoing training and safety consciousness that is
a part of our club. 2) I value the assistance that club
members render to each other, and 3) I understand
that soaring in our area depends on concerted actions
by the club to keep facillities open and keep our
aviation and non-aviation neighbors working with us
instead of against us.

Only if you fly less than 10 hours a year.

The required engine/propeller maintenance (change the plugs &
re-torque the prop bolts) on my DG-400 can be done in 1 hour.
Additional time depends upon what breaks. As the engine is only run
10-15 hours a year things don't have a tendency to wear out much.

Come to Richland some time. I can't over exaggerate the convenience of
noticing the cu building in mid-morning and leaving work at lunch to
go play for the rest of the day.

Really? What about retrieves? Doing club duty when a commercial
operation is not available? Waiting in line to launch?

I suspect that once you factor those things out, the non-flying time
invested in the self-launcher starts to look like a much better deal.

I have trailered/flown into GA airports with my DG-400 where there has
been absolutely no glider activity and, generally, received quite a
bit of interest from power pilots. I use the opportunity to inform
them where they can go to get instruction and what it takes to
transition from power into gliders, as well as answering the usual
questions like what do gliders cost.

One power pilot, flying a rig that consumed 30 gal/hr, watched me land
after a 4 hour flight. He asked me how much fuel I burned during the
flight. I replied, "a couple of quarts". He was impressed!

These aren't the airframe maintenance items Frank was talking about, so
I didn't address them.

I agree the total time spent on the sport can be less with a
self-launcher (this us one of the reasons I have a self-launcher), for
all the reasons you mention, and especially if you can fly from a local
airport (as I do) instead of driving a few hours to the gliderport.
Another point is the time spent on maintaining the glider can usually be
done at the pilot's convenience (evenings, winter, etc).

By similar considerations, the additional cost of a self-launcher can
often be covered (or at least reduced substantially) by considering the
all the avoided costs and time.

Nonetheless, the _maintenance_ involved in a self-launcher is much
greater than a similar unpowered glider.

PIK-20E is notoriously time consuming. Our local DG-400 is showing a
similar tendency regardless of the requirements. Has something to do with
the prior owners, but the problems have included electrical and fuel and
steerable tail wheel over the years. Doesn't seem to fly as often as I'd
expect, though the current owner is very enthused, though rather perturbed.

Drove through there twice earlier this week on a road trip to deliver a
glider to Cle Elum. Monday afternoon (early) looked pretty good for April
though the high stuff was coming in pretty quickly. The terrain between
Ellensburg and Yakima looked very intimidating.

We flew off our winch yesterday. Of the 20 or so launches, more than half
hooked soaring flights (We weren't pushing back to the fence, so 1600agl was
typical launch height). Nice cu to 11,500 despite all the media howling
about the snow storm (tracked further south than expected, 3ft in places).
$8/launch.
