25 years after it was written, Soaring reprinted (unabridged) Dave's 1986 soaring safety article.
Article on flying safety, especially how not to kill yourself learning mountain and competition flying.
Not for the queasy. Often remembered for:
I will not follow another pilot... and
It is much more important to know the limits of your knowledge and ability than to know everything, and certainly more practical.

Notes on flying the Monnet
Monerai Sailplane back in the 1980s
Soaring has been a huge part of Dave’s life with almost 4,000 hours in gliders, including 1000+ hours in his Antares 20E electric self-launcher, 1400+ hours in motor-gliders, around 100 contests, and 120,000+ miles XC. Dave now competes with his Antares (18-meter and open class). The high-point of Dave's soaring career has been a day win in the Open Class Nationals at Uvalde in his Antares, though past awards include the 1994 Giltner trophy (fastest speed in the USA 15-meter nationals), and the 1985 Shapiro trophy (fastest pilot in New England). Dave lives near Boston Massachusetts with wife Renee and parrot Rupert.
Dave starting soaring in 1974 with the MIT Soaring Association and began competition flying in 1978. Dave won the 1985 regional contest at Sugarbush without functioning varios or flight computer, and the lack of helpful instruments aggravated him so much he started developing a new avionics package. Dave’s flight computer designs subsequently introduced many firsts we now take for granted: a database of turnpoints, use of vector wind in all calculations, accurate vector wind measurement, complete task planning including time management, final glide around turnpoints, alternate landing spot location and final glide, and many more. On the first day of the 1991 World Championships in Uvalde, Dave’s first commercial design was in two of the three winning cockpits. Twenty years later in the USA 2011 Open Class Nationals at Uvalde, Dave’s ILEC SN10 was in the open class champion’s cockpit and the day winner’s cockpit 6 of 8 days, and these instruments are flown by thousands of pilots in more than 20 countries. In the 2012 World Gliding Championships in Uvalde, the ILEC SN10 was the flight computer and vario of choice in Dick Butler's Concordia, the world's highest performance sailplane. In 2014 winning pilots flying with ILEC SN10 included Ray Gimmey (USA 15-meter national champion) and Tilo Holighaus (Spanish Sailplane Grand Prix).
To bring the FLARM® traffic awareness and anti-collision system to USA soaring, Dave took a year off from professional pursuits and joined the FLARM® team for 2010, contributing heavily to FLARM® version 5 and the new PowerFLARM® product now flying in almost 1000 US sailplanes. To promote soaring, Dave exhibited and flew his Antares 20E in EAA's Oshkosh AirVenture airshow in 2009, 2010, and 2011. To improve racing glider water dump system reliability, Dave conceived and then developed in cooperation with Lange Aviation a new dump valve system, featured in Schempp-Hirth's new Quintus M glider and all new Antares gliders.
In addition to being a regular speaker at SSA conventions, Dave has written many Soaring magazine articles. In his professional life, Dave built and ran a software and systems consulting business, managed software development and systems for a major international financial market data provider, and now consults on software, systems, testing, and electronics.
