"This order specifies procedures for use by all personnel in the joint administration of the airspace program. The guidance and procedures herein incorporate into one publication as many orders, notices, and directives of the affected services as possible. Although every effort has been made to prescribe complete procedures for the management of the different airspace programs, it is impossible to cover every circumstance. Therefore, when a situation arises for which there is no specific procedure covered in this order, personnel shall exercise their best judgment. The order consists of six parts. Part 1 addresses general procedures applicable to airspace management. Part 2 addresses policy and procedures unique to Obstruction Evaluation. Part 3 addresses policy and procedures unique to Airport Airspace Analysis. Part 4 addresses policy and procedures unique to Terminal and En Route Airspace. Part 5 addresses policy and procedures unique to Special Use Airspace. Part 6 addresses policy and procedures regarding the integration of Outdoor Laser Operations, High Intensity Light Operations, and integration of Rockets and Space-Vehicle Operations into the National Airspace System."
