1 WILLIAM W. MELVIN Education: B. S. Mechanical Engineering, University of Texas, 1956.Tau Beta Pi; University of Southern California, ALPA Accident Investigation Course, Military: Patrol Plane Commander, U.S. Navy; Transport Plane Commander, U.S. Navy Reserve. Pilot experience & Ratings: Pilot for Delta Air Lines, began July, 1960, retired June Most recently served as captain on MD-11. ATR: CV-240/340/440, DC-6/7, DC-8, DC-9, CE 500, B-727, B-767, L-1011, MD-11. Commercial privileges: Single & Multi-engine Land, Single & Multi-engine Sea and Gliders. Air Line Pilots Association (ALPA): Chairman Airworthiness & Performance Committee ( ), member since Past service as Local Air Safety Chairman, Central Air Safety Chairman, delegate to 15 International Federation of Air Line Pilots Associations (IFALPA) conventions, member SAE A-4 committee, member of the Boeing 767/757 evaluation committee, member IFALPA Airworthiness Study Group, member ICAO WIST study group, member Joint Aviation/Industry Landing and Takeoff Performance Task Group. Member, National Research Council Committee on Wind Shear ( ). Member, National Research Council Committee on Aircraft-Pilot Coupling, Author & Lecturer: Technical papers and articles on wind shear and other subjects such as accelerate/stop, automation, manual control, fly-by-wire, noise abatement, etc. Past Contributing author for Flight Crew magazine (now extinct). Lecturer at ALPA Air Safety Investigator's Training School, the University of Colorado and Southeastern Oklahoma State University. Accomplishments: First described how an aircraft could be thrust deficient and land short in a decreasing tailwind shear in 1969 (AIAA ). Later updated article (Flight Safety Foundation Vol 5, No. 3) is referenced in NTSB report of Iberia DC-10 accident at Boston ( ). Described problem of flight directors and approach couplers in wind shear (1969). Described why potential flight path instruments would not work properly in wind shears and why pilots and autothrottles would under-react to wind shear because of inertial acceleration (Flight Safety Foundation, 1975). Developed argument for performance effects upon aircraft from downdrafts close to the ground (Flight Safety Foundation, 1975). Described equation to explain different effects of vertical and horizontal wind shear which is now called the "F Factor" (1975--description first published in NASA Conference Publication 2270, 1982). Explained why three types of airspeed increases which occur during wind shear encounters are not caused by pilot action and why optimal trajectory studies prove the "stick shaker" technique for wind shear recovery is dangerous unless very close to the ground (SAE ). Described requirement for human factors consideration of pilot interface with automatic systems (SAE ) and flyby-wire control systems (SAE ). Defined ALPA requirements for an acceleration monitor. Described safety problem due to differences between certification and operation of rejected takeoff procedures (AIAA ). Described danger of mixed mode (part manual and part automatic) operation of flight controls (AIAA ).

2 Participant in the investigation of a number of wind shear and other performance related accidents and incidents. Awards: Recipient of Flight Safety Foundation/University of Southern California Award for "Contributions to the Safety of Flight" (1976); ALPA annual Air Safety Award (1977) for "Significant Contributions to Flight Safety"; ALPA Air Safety Outstanding Service Award (1981); IFALPA Scroll of Merit (1986); AIAA Atmospheric Environment Technical Committee Award for "Advancing Professional Growth in Understanding New Technology and Noteworthy Contributions in the Field of Atmospheric Sciences" (1989); ALPA Presidential Citation for Outstanding Service (1993); Aviation Week & Space Technology/ Flight Safety Foundation Distinguished Service Award (1993) for "Distinguished Service in Achieving Safer Utilization of Aircraft"; IFALPA Clarence N. Sayen Award (1994); Boeing-President s Award for "Contributions to Aviation Safety" (1997); Boeing Collier Trophy Award for ALPA participation in B-777 evaluation. Co-recipient with Dr. Angelo Miele and Dr. Tong Wang of the O. Hugo Schuck award from American Controls Conference (1989) for the best paper of 1988, "Optimization and Guidance of Penetration Landing Trajectories in a Windshear". Professional Societies: Member SAE, AIAA, ISASI. Consultant: (A) Dr. Angelo Miele and Aero-Astronautics Group of Rice University on Optimal Trajectory Studies of Aircraft in Wind Shear which has been funded by NASA, ALPA, Boeing, the State of Texas and the Aviation Research and Education Foundation. The result of this work has (1) proven the best (optimal) trajectories for flight in wind shears, (2) shown that deliberate attempts to fly at high angles of attack (stick shaker) will cause aircraft to crash in wind shears that are only half as severe as can be survived with an optimal trajectory, (3) provided an explanation for the airspeed increase associated with accident aircraft just prior to ground impact, (4) developed guidance laws for flight in wind shear, (5) shown that attempting to fly at a constant pitch in a wind shear is inferior to a variable pitch technique required to maintain a quasi optimal trajectory, (6) shown that less than normal pitch rates result in best wind shear performance, (7) developed guidance for optimally landing when a wind shear is too strong to escape, and (8) proven the best technique for survival after the limiting angle of attack has been reached. (B) Office of Technology Innovation, National Institute of Standards and Technology, U.S. Department of Commerce. Other: (A) Holder of several patents related to instrument flight systems for aircraft. (B) Past Director of Air Safety Workshop (now extinct). (C) Dean of Technology for International Civil Aviation University (ICAU), Wrote the performance manual and edited others. ICAU was pioneered as advanced training for professional pilots, using the distance based learning concept. It is now defunct.
