On March 16, 2011, the Transportation Research Board published Legal Research Digest 11: Survey of Minimum Standards: Commercial Aeronautical Activities at Airports, prepared by Kaplan Kirsch & Rockwell and Aviation Management Consulting Group. Legal Research Digest 11 describes the principal legal requirements for airport minimum standards, presents the results of a survey and interviews on the topic, and provides a compendium of comparative minimum standards for the commercial aeronautical activities that commonly occur on airports. The Digest should be useful to airport lawyers and airport managers and others involved in developing and implementing airport minimum standards.
