Fellow aviator Ilmari Rintasalo flew his last flight on Christmas eve

RIP.

It seems that the accident was the consequence of airbrakes unlocked.
The ASW22 pilot was performing a self-launch. Climb rate was
insufficient, and a wing tip hit a powerline.
The glider came to rest inverted, while Hi-T cables were lying by,
delaying the rescue of the poor pilot by nearly an hour.

Local pilots, under the initiative of spanish Pepe Gresa, I believe,
started an action to put some pressure on glider manufacturers, so
that they develop and implement some system to make these frequent
take-off mistakes a non-event. We should all strongly support this
initiative.

Karel Termaat imagined a very simple 3-Led warning system, based
around 2 proximity swithces and one pressure switch on the Ptot line.

The Piggott Hook also can help prevent the airbrakes being sucked open
at take off.

The 302 vario, and perhaps others, can do the same thing, if it is used
as the gear warning system. A loud tone alerts the pilot as the glider
accelerates past 25 knots if the airbrakes are unlocked. It works well
in my glider.

Additionally, a simple stop just behind the spoiler handle acts as a
Piggot hook. The stop is out of the way when the handle is rotated into
operating position.

And finally, my procedure to always lock the air brakes unless my hand
is on the handle, even if the glider is on the ground and I am not in
the cockpit.

Yes the 302 airbrake warning works well, perhaps just a bit too well.
I'd like the trigger speed to be about 5kts higher so it doesn't go
off quite so often on takeoff. (Std class glider with airbrakes part
open for every launch).

A better thread title may be "avoiding unintended airbrake opening
during launch".

Easier: Always take off with brake half open. This give you better
aileron control on takeoff. On a schleicher glider, you want the brake
open as the towplane takes out slack to have the wheel brake on so you
don't over run. Cycle the brakes a few times to show the tow pilot you
now what you're doing. Just leave your left and hand on the airbrake,
and close when you have aileron control (then move to flap handel).
It's really hard to forget a handle that is in your left hand!

I do a quick check of the spoilers at 1000 feet as I raise the gear,
just swing my head left and right to make sure there isn't anything
sticking out of the wing. Locked spoilers have been known to pop open.
They should have a noticeable over-center clicking action as several
pounds of force is applied in closing. If your ship doesn't, have them
checked.
