One of the major failings of the aviation community and manufacturers
is the design and installation of angle of attack indicators. AOA
indicators, long used by the military, are the only true solution to
these types of stall accidents.
Especially valuable to soaring performance as AOA can be used
throughout the performance envelope.
Soaring organizations world wide could easily fund the research and
development of accurate, reliable and inexpensive AOA units for new
and to retrofit gliders.
