ASI clients have included the FAA; domestic and international airport owners and operators; local governmental agencies and citizen action groups; wind energy developers; private and public sector builders and planning/architectural/environmental firms; and major law firms, insurance companies and communications companies (see representative client list).

Gary Allen

Dr. Allen has over 35 years of technical and legal experience in aviation, engineering, and environmental planning. A substantial part of his career has been devoted to airport compatibility planning and analysis such as noise/land use, airspace modeling, aircraft accident potential, land use risk assessment and electromagnetic interference (EMI) studies. In recent years, Dr. Allen has been heavily involved in evaluating the airspace issues and regulatory compliance under FAR Part 77 for alternative energy projects around the United States, particularly wind energy and biofuel projects as well as electric power systems.


During his career, Dr. Allen has also managed noise monitoring and computer modeling studies at civilian airports across the nation including Los Angeles International, San Diego's Lindbergh Field, Brown Field, John Wayne Airport, Salt Lake City International, Houston Intercontinental, Will Rogers World and Wiley Post airports in Oklahoma City, Oakland International, and SeaTac International. Dr. Allen also assisted these airport operators in developing noise abatement/land use compatibility plans that met both legal and public acceptability criteria. He has been similarly involved in Air Installation Compatible Use Zone (AICUZ) studies for military airfields such as NAS Alameda, NAS Barbers Point, MCAS Kaneohe Bay, and CGSC Elizabeth City.

Dr. Allen's focus over the last decade has been advising wind energy project developers and utility companies on Federal Aviation Regulations (FAR) compliance. That includes aviation constraints analysis during the planning phase and coordinating obtaining approvals from the FAA under the FAR Part 77 process for wind and electric power systems.


Dr. Allen holds a law degree from Western State University College of Law and a Ph.D. form California Western University. He also holds an engineering degree and advanced degrees in environmental studies from California State University and certificates in Urban Planning and Environmental Analysis from the University of California, Irvine. All of his graduate studies emphasized aviation and airport operations.

Jerold Chavkin
Vice-President of Airspace Operations

Mr. Chavkin has over 40 years of experience as an engineer, pilot, aviation programs administrator, and consultant. In his government career, Mr. Chavkin held increasingly more responsible positions with the United States Air Force and the Federal Aviation Administration (FAA) culminating with his appointment as Regional Administrator of the Western Pacific Region of FAA. He has an extensive technical background and experience in governmental and public relations as well as a thorough knowledge of the regulatory, security, safety, and air traffic control functions of civil aviation. Mr. Chavkin is a commercial pilot and holds single and multi-engine, instrument and jet ratings.


Prior to joining the FAA, Mr. Chavkin served seven years in the U.S. Air Force as Power Plant Project Engineer at the Air Force Power Plant Laboratory and XB-70 Program Office at Wright Patterson Air Force Base.

Mr. Chavkin began his FAA career as Chief Propulsion Engineer and then was assigned as the Manager of Plans and Programs for the National Supersonic Transport Program. During this six-year period, he was responsible among other things for engine development, preparation of congressional testimony and budget and planning documentation.

For 16 years, Mr. Chavkin served on the FAA Washington Headquarters staff where his key responsibilities included executive direction of the FAA National Rotorcraft Program, the Aircraft Engineering and Certification Program, the System Engineering Office and Associated Airport Capacity and Air Traffic Control System Development, and the Short Haul Aviation System Development Program.

Mr. Chavkin was then assigned for three years as Deputy Regional Administrator of the FAA Central Region in Kansas City where he shared direction of the four-state region and was also responsible for small aircraft certification worldwide.

He completed his FAA career as Regional Administrator of the Western Pacific Region headquartered in Los Angeles where he directed FAA operations for two years in the western states, U.S. Territories in the Pacific and the Pacific Rim nations. In this role, Mr. Chavkin was principally responsible for relations with state and local governments, the aviation industry and the military. He also directed major international aviation activities with Civil Aviation Authorities in the Pacific Rim.

Since 1990, Mr. Chavkin has consulted on a number of major domestic and international aviation projects including a new rail transit system through LAX, a proposed bi-national air carrier airport on the U.S./Mexico border near San Diego, the modernization of the Australian Airspace System and a new Master Plan for the Guam International Airport. He also consulted on the management and operation of ten privately managed Los Angeles County and Riverside County general aviation airports. Mr. Chavkin has been involved in managing airspace obstruction evaluations for numerous wireless communications, wind turbine and utility company projects. Mr. Chavkin has also provided consulting and expert witness services to a number of major law firms throughout the U.S.


Mr. Chavkin holds a Bachelor of Science in Mechanical Engineering from the Illinois Institute of Technology and a Master of Science in Air Transportation from the University of California, Berkeley.
