How Low to Spin?? by
Paul M. Cordell
How Low to Spin??
I was proudly shown a IGC file this weekend. This file show the aero tow
thru a thermal and a release into sink. Our proud pilot was unable to
find the thermal and started a downwind leg for a landing. As he turned
base leg, he flew into a 2-5 kt thermal. Instead of completing...

poor lateral control on a slow tow? by
Doug[_5_]
As an aerodynamicist/flight dynamicist recently re-soloed after 25 years
off, people keep asking me hard questions. One that has come up recently is
why a heavy glider on tow feels horrible, but thermalling in the same glider
at lower speeds is fine? (see also Mike Fox's article on aerotowing...

Safety of winch launch vrs. aero tow? by
Gary Boggs
Someone must have already compared the safety of these tow launch methods.
What do the statistics show is the safer method of launch? Aero tow seems
to involve more inherent dangers to me. For one thing, there is just more
time for things to go wrong. What could be more dangerous than to tie...

US Dollar sinks to new low against Euro by
Mike Stringfellow
The US dollar is now valued close to 0.75 Euro, down from its peak of
1.25 a couple of years ago. Analysts say it may go even lower, with
some projecting exchange rates of 0.7 (1.4 dollar to the Euro).
This has pretty much put the kibosh on my goals of buying a new
European sailplane. A model...

Flarm in the US by
Steve Freeman
Curious about the use of Flarm in the US. Was told by another pilot
that the frequency used by Flarm is not approved for that category of
use in the US. Is that true? If it is, do they make units that use a
US approved frequency?

Cheap GPS Loggers for FAI Badges - Status? by
Papa3
I notice from the brief minutes of the FAI meeting in Lausanne that a
proposal to use Commercial Off The Shelf (COTS) flight recorders was not
accepted. In other words, the widely available, cheap units are again
rejected in favor of expensive, proprietary units. I'd like to know...

Not sure how accurate FB translate is, but it appear as if Mr. Kawa had some sort of incident with an electric motor not working and a rough uphill landing. Gas, electric or jet be careful guys!
