Air Line Pilots Association (ALPA): Chairman Airworthiness & Performance Committee(1977-1993), member since 1968. Past service as Local Air Safety Chairman, Central Air SafetyChairman, delegate to 15 International Federation of Air Line Pilots Associations (IFALPA)conventions, member SAE A-4 committee, member of the Boeing 767/757 evaluationcommittee, 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 (1982-1983).Member, National Research Council Committee on Aircraft-Pilot Coupling, 1995-96.

Author & Lecturer: Technical papers and articles on wind shear and other subjects such asaccelerate/stop, automation, manual control, fly-by-wire, noise abatement, etc. Past Contributingauthor for Flight Crew magazine (now extinct). Lecturer at ALPA Air Safety Investigator'sTraining School, the University of Colorado and Southeastern Oklahoma State University.

Accomplishments: First described how an aircraft could be thrust deficient and land short in adecreasing tailwind shear in 1969 (AIAA 69-796). Later updated article (Flight SafetyFoundation Vol 5, No. 3) is referenced in NTSB report of Iberia DC-10 accident at Boston (12-17-73). 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 andwhy pilots and autothrottles would under-react to wind shear because of inertial acceleration(Flight Safety Foundation, 1975). Developed argument for performance effects upon aircraftfrom downdrafts close to the ground (Flight Safety Foundation, 1975). Described equation toexplain 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 whythree types of airspeed increases which occur during wind shear encounters are not caused bypilot action and why optimal trajectory studies prove the "stick shaker" technique for wind shearrecovery is dangerous unless very close to the ground (SAE 86-1701). Described requirement forhuman factors consideration of pilot interface with automatic systems (SAE 83-1501) and fly-by-wire control systems (SAE 85-1836). Defined ALPA requirements for an accelerationmonitor. Described safety problem due to differences between certification and operation ofrejected takeoff procedures (AIAA 93-4005). Described danger of mixed mode (part manual andpart automatic) operation of flight controls (AIAA 2003-6705).

Participant in the investigation of a number of wind shear and other performance relatedaccidents and incidents.

Professional Societies: Member SAE, AIAA, ISASI.

Consultant: (A) Dr. Angelo Miele and Aero-Astronautics Group of Rice University on OptimalTrajectory 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 workhas (1) proven the best (optimal) trajectories for flight in wind shears, (2) shown that deliberateattempts to fly at high angles of attack (stick shaker) will cause aircraft to crash in wind shearsthat are only half as severe as can be survived with an optimal trajectory, (3) provided anexplanation for the airspeed increase associated with accident aircraft just prior to groundimpact, (4) developed guidance laws for flight in wind shear, (5) shown that attempting to fly ata constant pitch in a wind shear is inferior to a variable pitch technique required to maintain aquasi optimal trajectory, (6) shown that less than normal pitch rates result in best wind shearperformance, (7) developed guidance for optimally landing when a wind shear is too strong toescape, and (8) proven the best technique for survival after the limiting angle of attack has beenreached.

(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), 1996-98.

Wrote the performance manual and edited others. ICAU was pioneered as advanced training forprofessional pilots, using the distance based learning concept. It is now defunct.
