  • Ergonomics of Paragliding Reserve Deployment
    Contemporary Ergonomics and Human Factors 2020. Eds. Rebecca Charles and Dave Golightly. CIEHF. Ergonomics of paragliding reserve deployment Matt Wilkes1, Geoff Long1, Heather Massey1, Clare Eglin1, Mike Tipton1 and Rebecca Charles2 1Extreme Environments Laboratory, University of Portsmouth, 2 Rail Safety and Standards Board ABSTRACT Paragliding is an emerging discipline of aviation, which is considered relatively high risk. Reserve parachutes are rarely used, but typical deployments are at low altitude, with pilots under the extreme stress of a life-threatening situation. To date, paraglider equipment design has focused primarily on weight and aerodynamics, so reserve parachute deployment systems have evolved haphazardly. Our study aimed to characterise deployment behaviours in amateur pilots. Fifty-five paraglider pilots were filmed deploying their reserve parachutes from a zipline. Test conditions were designed for ecologically valid body, hand and gaze positions; cognitive loading and switching; and physical disorientation akin to a real deployment. The footage was reviewed by two groups of subject matter experts. It was noted that pilots searched for the reserve handle using the hip as an anatomical landmark and tried to extract the deployment bag upwards, irrespective of optimum direction. Recommendations, which are being incorporated into the latest draft of the European Norm for harness design included: positioning reserve handles at the pilot’s hip; better system integration between different manufacturers; and containers being designed so deployment bags are extractable at any angle of pull. Deployment in a single, sweeping action should be encouraged in preference to the multiple actions sometimes taught. KEYWORDS Equipment failure, personal protective equipment, accidents, aviation Introduction Paragliding is a widely practiced form of unpowered flight (Paragliding Manufacturers’ Association 2014).

  • Beginners Guide to Kite Boarding
    The Complete Beginner’s Guide About Kitesurfing What Is Kitesurfing? For some, it does not even ring a bell although, for others, it means everything and they build their life around it! Whether you have already witnessed it in person on your last vacation to the beach, maybe over the internet in your news feed or even in pop culture, for sure it made you wonder… What the heck are these guys doing dangling in the air under that big parachute? And how are they even doing it? If we were to talk to someone in the early 1960s about space exploration, let alone landing on the moon they would have thought we were crazy. What if we were to tell someone today that they can have the time of their life by practicing a water sport that involves standing up on a surfboard, strapped in a waist harness while being pulled along by a large kite up 25 meters in the air? That person probably wouldn’t believe it. Well, here we are today with hundreds of thousands of people learning and practicing kiteboarding every year. In this Complete Beginner’s Guide, we will go from the inception of the sport to where it is today and everything in between to understand what kitesurfing is all about. This guide will inform you about the history and origins of kitesurfing, the equipment, the environment, what it takes to become a kiter as well as the benefits of becoming one. Moreover, we will cover everything there is to know about the safety aspects of this action sport and the overall lifestyle and culture that has grown around it.

  • BHPA Elementary Pilot Training Guide
    The British Hang Gliding and Paragliding Association VERSION 2.4 welcome! JOE SCHOFIELD, EDITOR Since the early 1970s, the BHPA and its predecessors (the British Hang Gliding Association and the British Association of Paragliding Clubs) have worked hard to build a reputation as a well-run and respected sports governing body, and it has for many years been recognised and respected by the Civil Aviation Authority, the Royal Aero Club and the Fédération Aeronautique Internationale. Assisted by highly-qualified professional staff, the BHPA runs a pilot rating scheme, airworthiness schemes for the aircraft we fly, a school registration scheme, an instructor assessment and rating scheme, a pilot development structure and training courses for instructors and coaches. Within your membership fee is also provided third party insurance and, for full annual or three-month trial members, a subscription to the highly-regarded monthly Skywings magazine. The Elementary Pilot Training Guide exists to answer all those basic questions you have such as: ‘Is it difficult to learn to fly?' and ‘Will it take me long to learn?' In answer to those two questions, I should say that it is no more difficult to learn to fly than to learn to drive a car; probably somewhat easier. We were all beginners Photo: Kath Wallace once and are well aware that the main requirement, if you want much more than a ‘taster', is commitment. Keep at it and you will Welcome to free flying and to the BHPA’s Elementary Pilot Training succeed. In answer to the second question I can only say that in Guide, designed to help new pilots under training to progress to spite of our best efforts we still cannot control the weather, and their first milestone - the Elementary Pilot award.

  • United States Hang Gliding & Paragliding Association 1 FAA Resources Page for Instructors the U.S. Hang Gliding and Paraglid
    United States Hang Gliding & Paragliding Association FAA Resources Page for Instructors The U.S. Hang Gliding and Paragliding Association (USHPA) is required by the FAA to ensure that flight training provides sufficient understanding of information provided in the FAA Pilot's Handbook and the Powered Parachute Handbook, and that all hang glider and paraglider student pilots have access to both handbooks. The Federal Aviation Administration (FAA) maintains these instructional materials as free online resources to provide essential information for all pilots. Content from both manuals is already integrated into USHPA's pilot training program as applicable. The USHPA has compiled a list of some of the most relevant materials from both handbooks and summarized it, along with the corresponding chapter numbers, below. An overview of FAR part 103 is also included. (See here for a webpage with this information for student pilots.) Please feel free to reference this list and recommend the handbooks or specific chapters to students that might benefit from further study. FAA Manual Topics Preflight and Other Flight Preparations Chapter 5, Powered Parachute Handbook Before launching, it’s important to complete a preflight to ensure that everything is flight- ready. A key part of the preflight is confirming that everything is assembled correctly and is in good condition on the hang glider or paraglider. Students (and their instructor if flying tandem) should also make sure that they are mentally and physically prepared for the flight, the weather conditions are appropriate, and no external pressures should disrupt the flight. (PPH 5-1) Finally, before launching, the pilot(s) must ensure that they are securely attached to the glider.
