Interesting. Just what was on the glider to "Shortly after
broadcasting his position, the (air ambulance) pilot reported that
the aircraft's traffic alert and collision avoidance system
indicated 'traffic 800 ft below'.
Sounds like ADSB?
Not necessarily. If the Air ambulance had TCAS as stated, the TCAS
will trigger any nearby Mode C transponder even when not in radar
coverage and generate a warning. So the glider only needed Mode C to
be seen by the TCAS.
Actually sounds like the system worked as intended including the
radio calls and responses.
The other B200/glider incident was more serious in that there were no
warnings and no evasive actions taken by either party.
Maybe Mode C transponders are a good idea. I hate to think of what
will happen when some passengers in a regional airliner see a glider
pass quickly down one side of the aircraft 200 feet away, or the
regional airliner gets overstressed in taking violent evasive action
or worse, actually collides with the glider.
The gliding movement doesn't have a leg to stand on here, what with
the enthusiastic adoption of Flarm. Ibis and pelicans etc through the
windscreen of a regional airliner/flying doc/FIFO aren't our problem.
The number of KingAirs flying around doing these things is growing.
Wombat, TCAS does have a collision algorithm and even generates
escape commands.
If you get a transponder make sure it does Mode S and is ADSB ready.
No, I don't sell them and have no intention of so doing.

All IFR pilots need to understand that, while there is perhaps one
air ambulance airborne in G airspace in high summer, there are
perhaps 50 gliders around there somewhere. Not to mention Ibis,
Pelican's, Eagles that glider pilots look for. Look out!! All of you!!!

I could have been, but i was not flying out of Temora on that day,
nor did I ever have ABSB.
