Now, if all gliders had AoA gauges, you could jump from one glider to
another and not worry about what the right approach speed is for the
glider you happen to be in.

Whatever happened to the old fashioned custom to familiarize oneself
with the particularities of a glider before flying it?

Right now, the closest we have is the yellow triangle on german
gliders - approach speed at max gross, I think? (please correct me if
I'm wrong on that one).

Nothing to do with German, it's a JAR requirement. Suggested minimal
approach speed at max gross without water ballast. The triangle is
handy, but just reading the POH works, too.
