I like having radios in both aircraft, but there are also other options
for some pilots:
*DG owners can install factory approved Piggot hooks that will prevent
the spoilers from opening completely.
*Pilots with Experimentally licensed gliders may be able to install a
similar device on their glider.
*Other glider owners can install a "spoiler unlocked during takeoff"
warning system. I did this using my Cambridge 302, which will sound off
if the spoilers are unlocked as the speed goes above 20 knots during the
start of the launch. This is a good choice for self-launchers, since
there won't be a tow pilot to help them notice the problem.
*Pilots buying gliders can choose one that won't deploy the spoilers,
even if they are unlocked. The ASW 27 (and later Schleicher models, I
assume) has angled spoiler caps to achieve this, and I think Mosquito
style glide path control flaps will not open unless held open.
