What are DOT Orders?

The term “DOT Order” is used to describe several different mandates or instructions issued by DOT. The orders can be divided into two categories, economic orders and administrative orders

Economic orders, pertaining to aviation, are called CAB Orders or DOT Orders. The terms are used to describe Civil Aeronautics Board (CAB) Orders and their continuation, DOT Orders. The CAB was an economic regulatory agency that was abolished in January 1985 under the Civil Aeronautics Board Sunset Act of 1984 (98 Stat. 1703) and the Airline Deregulation Act of 1978 (92 Stat. 1744). For more information about the CAB and its successor agencies, go to
