I enrolled in Chandelle SF’s training program, and a year later, was a rated hang glider pilot flying the Sierra. Soon after, I met my partner in life, Wally Anderson, who now owns and operates Merlin Flight School, a paragliding school in the SF Bay area. About 10 years ago, I learned to fly paragliders, so now have the choice of 3 types of soaring flight to participate in.

Chapter 2 Inventory of Facilities
Chapter 2 – Inventory of Facilities Chapter 2 Inventory of Facilities One of the initial tasks in the preparation of an airport master plan is the collection of information on the condition of existing facilities and services. This inventory of data is necessary to not only evaluate the physical attributes of airside and landside infrastructure, but also to complete subsequent study tasks, such as demand/capacity analyses and the determination of facility requirements. Information collected focuses on the use, size, quantity, type, area, operational intent, and other characteristics of the airside and landside components of an airport. Typical categories of information that are collected include history, physical infrastructure, regional setting, surrounding land uses, environmental features, historical aviation activity, business affairs, and socioeconomic demographics of the surrounding community. Several sources of information were referenced to compile a comprehensive database of the facilities and services at the University Park Airport (Airport). These included, but were not limited to, the previous Airport Master Plan, recent National Environmental Policy Act (NEPA) documents, the Airport website, the Terminal Area Master Plan, the Land Use Plan, and the Airport Layout Plan (ALP). In addition, historical enplanements, aircraft operations, based aircraft, aircraft fleet mix, enplaned cargo, and automobile parking data were obtained from Federal Aviation Administration (FAA) databases and Airport records. Finally, an on-site visual -

The Design and Testing of an Airfoil for Winglet on Low-Speed Aircraft
Extracting Energy from Atmospheric Turbulence with Flight Tests Chinmay K. Patel Acuity Technologies Inc. Menlo Park, CA 94025 USA [email protected] Hak-Tae Lee University of California, Santa Cruz Moffett Field, CA 94035 USA [email protected] and Ilan M. Kroo Stanford University Stanford, CA 94305 USA [email protected] Accepted by the XXIX OSTIV Congress, Lüsse-Berlin, Germany, 6 August – 13 August 2008 Abstract Birds frequently use the energy present in the atmosphere to conserve their energy while flying. Although en- ergy in the form of thermal updrafts is routinely used by pilots of full-scale and model sailplanes, the energy in atmospheric turbulence has not been utilized to its full potential. This paper deals with the design of simple control laws to extract energy from atmospheric turbulence. A simulation-based optimization procedure to de- sign control laws for energy extraction from realistic turbulence was developed, leading to about 36% average energy savings for a ‘bird-sized’ glider. Flight test results are presented to demonstrate the energy extraction concept and validate the predicted savings. The emergence of ultra-light sailplanes has opened up the possibility of utilizing this form of ‘gust-soaring’ for a class of manned sailplanes, and the concepts presented in this paper can serve as a background for understanding and applying the techniques to extract energy from atmospheric turbulence.

Recommended Safety Proficiency Standards for Hang Gliding SafePro Delta A Hang Gliding Safety and Training Program * by Stein Arne Fossum - Raymond Caux ____________________________________ The history of hang gliding has been written in a few years, where new barriers have been broken virtually every day. It has developed into a full-blooded aviation activity, meaning it is no longer simple and easy to learn, potentially more dangerous for the "self-learners", while the opposite may be true for the ones receiving proper training. In the race for more efficient gliders and new developments (fixed wings, thermal and cross country flying), one often forgets that human nature needs time to learn to perform new tasks in a safe manner. The training methods are more on the "ground skimming level", while reality calls for cross country flying. Looking at the levels of flying already reached (limited to foot launch, no power) along the history of hang gliding, we see 5 distinct stages.
