SSA petition to allow transponder to be turned off

I'm definitely in favor of gliders w/ transponders and see this as
another step towards conserving battery power for when you need it. i.e.
when you are near a high traffic airspace where the chances of crossing
paths with someone with either TCAS or ATC coverage is increased.

What about a discrete transponder code specifically for gliders??????

I understand that there is at least one area which has an agreement to
use (seems like it's 0440 or something similar) a code specifically for
gliders. Why not also work on getting this code agreed to for all of
the U.S. at the same time that they are working on the below mentioned
waiver.

Contacting your director will likely get you the latest information on
this subject, but here's what I was told last year:

-The Reno area does use 0440, and it works for them, because there are
many gliders flying there that do have transponders, and the controllers
are familiar with how a glider operate, so knowing which blip is a
glider is useful.

-The above is not true for most of the USA.

-The specific code, 0440, is used for other things around the country -
not many, but it means other changes would have to be made.

-Some have suggested making gliders easily identifiable by a specific
code might not work in our favor because controllers and others would
know "who" to be annoyed at, justified or not.

-So, the last I heard, doing a special code was likely to be on a
cas-by-case basis.

Keep up the good work!

SSA Transponder Petition Published
By Dennis Wright
Posted Thursday, February 19, 2004

The SSA petition asks that SSA members be allowed to operate
transponder-equipped gliders with the transponders turned off, when
the glider is being operated more than 40 nautical miles from the
primary airport in Class B airspace and more than 20 nautical miles
from the primary airport in Class C airspace. Currently, Federal
Aviation Regulation 91.215[c] requires that all aircraft equipped with
a transponder and operating in controlled airspace have the
transponder on.
