Aerodynamics of carrying water by
Gene Whitt
Y'all,
Been many years on rec.aviation.student but even more years since
gliding. Unable to explain the 'why' of water ballast to increase

ASG-29/ASW-27 wing refinish by
[email protected]
I have heard that the new ASG-29 and many of the ASW-27's have had a
noticeable spar cap shrinkage problem. I am looking for an unbiassed
discussion of this problem, the extent of the problem and possible
solutions (other than a wing refinish).

ContestID67

;-)
I have seen lots of wing tape. Many of the advertisements are for very
thin and flexible tape which conforms to the curves of the wing.
However, the cost can be prohibitive, especially if you assemble often.
A friend of mine...

Avoiding Vne by
K.P. Termaat
Yesterday evening I talked with a friend about avoiding excessive speed when
recovering from a spin in a modern low drag glider with the somewhat larger
span.

AOA indicator by
Jonathan St. Cloud
Was just reading about the Aspen suite of avionics for GA
http://www.flyingmag.com/way-to-aoa?src=PPC&dom=fb&con=Aspen-FB-Ads.
Was wondering if Air-Avionics Butterfly, LX 90XX or similar modern glide computers would be capable of such algorithms to have a working AOA?
