Help us with this petition for security on anti-collision systems

Interesting podcast on FLARM.

"In this episode we talk with Gerhard Wesp, Development Manager Avionics at Flarm Technology GmbH about FLARM, a collision avoidance system for gliders and general aviation. We talk about the history of the FLARM system as well as about newer developments such as the PowerFlarm. Mostly, however, we talk about how FLARM works and how PowerFlarm integrates with Transponders and ADS-B systems."

Omegatau - omega tau covers a mix if topics from engineering and science; the selection of topics is guided by our own interest (as well as listener suggestions).

A look from the engineering point of view.

I will not be signing the petition.
FLARM is a private enterprise and deserves to reap the rewards of its work.
FLARM is a optional instrument for pilots, not a mandated piece of equipment. The issue with contest pilots being required to use FLARM is an SSA matter.
I would hope that glider pilots choose to install a transponder BEFORE they add a FLARM to their aircraft.

Out of ignorance and curiosity, what are the relative proportions of glider collisions in the US between gliders versus between gliders and CA/GA aircraft?

From 1994 through 2013 there were 20 reported midairs involving gliders un the US - 12 were glider-glider, 3 were glider-towplane, 4 were glider-GA and one was towplane-GA (the glider was on tow). There were 16 total fatalities as a result.

These were only the ones that were serious enough to be reported to the authorities and recorded in the official record. There were probably others with minor or no damage that were not reported.

Based on the statistics FLARM is a more important investment than a transponder, though obviously that consideration includes the fact that the statistics reflect whatever deployment of transponders existed prior to introduction of Flarm and may have reduced collisions with other aircraft types over the period.

I would hope that glider pilots choose to install a PowerFLARM BEFORE they add a transponder to their aircraft, unless they routinely fly in airspace with lots of airliners (TCAS-equipped).

Why? Because with a PowerFLARM, the glider pilot can actively avoid transponder and ADS-B (mode S-ES) equipped aircraft, as well as other PF-equipped gliders that are likely to join him in a thermal. With only a transponder, your protection is entirely up to the OTHER aircraft, and in the case of most VFR traffic, will provide almost NO protection.

Of course, the best solution is to have both a transponder and PF....
