Alternate Title: HSPD 16 : [Classified]
National Security Presidential Directive 47/ Homeland Security Presidential Directive 16 are classified directives that address aviation security. According to the Rules and Regulations Plan for the Emergency Security Control of Air Traffic (ESCAT) ( Federal Register volume 71, no. 203/Friday, October 20, 2006), where they are referenced, the directives change how air traffic would be controlled in the event of a terrorist attack. Decisions on shutting down airspace would be given to the Department of Defense with the President as the only civilian to have veto power. The new plan allows the Department of Defense to determine when to call an Air Defense Emergency and to decide what airspace sectors would be involved in a shutdown, a change seen as being friendly to the economic community. The plan does not define an "end" to an emergency.
