EAA 2000 Coverage Home

[Email from Keith Peshak, 12.23 a.m., July 29, 2000]

At Oshkosh AirVenture2000 I demonstrated two aircraft collision avoidance displays on Thursday 7/27/2000 at 8:30 AM in Tent 2, and again on Friday 7/28/2000 at 7:00 PM in the AOL Pavilion. The aircraft equipage cost is $500 to repair the transponder from all of the FAA problems listed at http://www.gtwn.net/~keith.peshak/tn97_7.pdf, and looks like http://www.gtwn.net/~keith.peshak/aispkit2.jpg, $3000 for the receiver to see the other aircraft up to 52 miles away, which looks like http://www.gtwn.net/~keith.peshak/TailLight.jpg, and either free for the collision avoidance display software which looks like http://www.gtwn.net/~keith.peshak/AISP1.gif, or about $300 for the collision avoidance and terrain avoidance and obstacle avoidance and runway incursion avoidance display software which looks like http://www.gtwn.net/~keith.peshak/Oshkosh.gif

James Zerbe, Airport Engineering Specialist of the Wisconsin Department of Transportation in Madison had requested of the FAA regional office that we be allowed to flight demonstrate the system. The FAA response was threat to arrest.

I also discussed the major error in Technical Standards Order C74c dated 2/20/73, the section entitled 2.6 Decoding Performance c Side-lobe Suppression. If you build transponders to work as specified, then you will not see equipped aircraft on the new FAA radar, nor the Airline Traffic Collision Avoidance System.

According to Chuck Larsen, Executive Director Resident Education, who had canceled all of my scheduled forums already earlier this year, who now took my gate pass, refunded my money in cash, and had me escorted from the Oshkosh grounds by police, Tom Poberezny had made the decision, which he was just communicating, that my association, now and in the future, with EAA is terminated.

I don't believe that I used any more or worse profanity than General Chuck Yeager used in his forum 7/28/2000 at 10:00 AM in the Eclipse Pavilion, or uses before children in his activities with the Young Eagles program.

I have received the following "offer" from the FAA: They will "certify" that I said that my system meets TSO C74c, thereby allowing people to use it. They know full well that I have told them in no uncertain terms that it does not. Of course, it does the exact opposite of what is specified in that TSO, or it wouldn't work (ignores a pulse following P3, suppresses on a pulse following P1).

That last sentence is also true for every other aircraft transponder. You suppress on a pulse following P1, in opposition to the TSO, not a pulse following P3, in accordance with the TSO. If you suppress on a pulse following P3, then you will not appear on "radar" or TCAS.
