Collision Avoidance Systems for gliders

By having a motor glider (operated by another company) parked in front of
their hangar?

LOL, no, GM themselves makes it clear that they are the same company.
From http://www.sportys.com/press/bio.html
"Eastern Cincinnati Aviation (ECA), Sporty's closely affiliated fixed
base operator, was founded in 1988 to provide flight instruction, rental
aircraft, service and fuel sales for Clermont County/Sporty's Airport.
ECA also operates, maintains and manages all airport operations on
behalf of Clermont County. Avionics installation and repairs are also
available on the airport through a division of ECA, Cincinnati Avionics."

But, this is beside the point. Even if Sporty's has a financial interest
in ECA. Sporty's would not live or die, let alone notice, if the ECA
glider program folded. The same can not be said for Tom Knauff or Tim
Mara. Lastly, Smith & Wesson makes some *really* nice scissors but I
wouldn't exactly call them a scissors company.

Please support your glider companies.

peace,

When close to other transponder equipped gliders, the TPAS essentially goes
deaf. If both gliders are being interrogated by ATC or TCAS at very nearly
the same time, the nearby glider's transponder reply will occur while your
transponder replying as well. Your transponder blanks the TPAS receiver
during this period.

Allo, John.
Interesting.
This implies that the transponder-based collision avoidance system
in a transponder equipped aircraft is of little use when close to
another transponder equipped aircraft. A bit counterproductive,
perhaps?
What relative distance does this blanking occur below?
Jim

I contacted Zaon, asking for the closest distance an MRX could detect
another transponder. Zaon replied that in flight the closest range the
MRX can detect is about 200-300 feet.

Since it can display only in 0.1 nm (600 feet) increments, that's
plenty close enough! We all hope we've seen the other aircraft way
before the range indication reads 0.0, don't we?
