Press release from the CAFE Foundation

The CAFÉ Foundation's Inaugural NASA PAV Centennial Challenge concluded on August 11 in Santa Rosa, California, and brought forth remarkable performances by several Personal Air Vehicles (PAVs). This great event was made possible by support from NASA and Boeing Phantom Works.

Winning teams shared cash prizes from NASA totaling $250,000. Prizes were awarded for Shortest Runway, Lowest Noise, Highest Top Speed, Best Handling Qualities, and Most Efficient, with the grand Vantage Prize of $100,000 going to the best combination of performance overall. The first of five annual competitions, this launched NASA's vision for a new age of environmentally-friendly personal air travel.

Vance Turner's Pipistrel Virus flown by Michael Coates of Australia won $160,000 by demonstrating the best MPG (29.8), shortest takeoff distance (736 feet over a 50 foot obstacle), 2nd best top speed (162 mph - 140 knots) and most overall points. The impressive debut of the Virus, a high-tech, carbon fiber Experimental Exhibition aircraft produced in Slovenia will likely move it to the lead among the next generation of low cost aircraft.

Displaying the prize booty on the Sunday media day, 5 prizes and $160,000 in cheques.

David and Dianne Anders, winners of the $50,000 Noise Prize in a highly-modified RV-4, achieved a noise level 3 times quieter than most small aircraft. That this astonishing feat was accomplished while also flying 192 mph is truly a significant advance in reducing noise. A special, low-noise Whirlwind composite propeller combined with an Ultramet Ceramic Foam muffler were key components of the noise reduction modifications on this RV-4.

Dave and Dianne flew as a team and as the only female entrant she was subjected to some well meant
teasing from the other teams, here is the new NASA Approved Tape we wanted Dianne to try out !!

The $25,000 Handling Qualities Prize was fittingly won by the most popular of all personal aircraft, the Cessna 172 Skyhawk.

The event was well-attended by the press and public, who enjoyed the PAV Technology Pavilion hosted by EAA Chapter 124. The Pavilion exhibited hands-on demonstrations of several of the key enabling technologies for PAVs, including NASA's fly-by-wire intelligent flight deck, synthetic vision, and the exciting new bio-fueled aircraft engines from GSE.

CAFÉ's new telemetry system, including its ingenius "BlueBox" and ÜberBarograph, collected and streamed highly accurate flight data to the CAFÉ Flight Test Center. CAFE's computerized, traceable sound measurement system established a new standard for measuring PAV noise.

The gala Awards Banquet provided a joyous conclusion to the week-long flight competition, and was highlighted by NASA's Mark Moore delivering a compelling keynote address on the Future of PAVs.

## What makes the Pipistrel's results even more amazing was the aircraft were flown at the MTOW of 585 kgs.... (1290 lbs)

The aircraft were continually weighed after each event both with fuel and without fuel so the real performance could be calculated

Ken from NASA kept us entertained, not only with clarification of the rules but also with his talented ukulele playing

Well, what an amazing that a week at the CAFE challenge, there will be lots more information coming through in the next couple of weeks as we get all the photographs and performance information from the organisers so please stay tuned for another newsletter shortly. Take care Michael Coates
