This AC describes the communication process between a pilot-in-command of a TARMAC delayed aircraft and local air traffic control (ATC). In addition, air carrier (Air Carrier Operations Center/Dispatch) communications related to TARMAC delayed aircraft with the Air Traffic Control System Command Center (ATCSCC) are addressed.

This advisory circular provides information to customers of the National Airspace System (NAS) in regards to the implementation and use of the dual J80 route procedure. The concept of the dual J80 route is to provide a near-term alternative for aircraft that normally file their flight on J80, westbound from New York and Philadelphia area airports.

CDRs provide more flexibility for selecting an alternate departure for specific airport when traffic constraint such as thunderstorms, turbulence, and periods of excessive demand exist. Use of a CDR reduces key-entry inputs for controllers and minimizes read-back time between tower staff and pilots, which creates an abbreviated clearance.

This Advisory Circular replaces AC 90-102 and provides guidance to customers of the National Airspace System (NAS) regarding changes to the traffic management process for managing flights through a constrained area with an Airspace Flow Program (AFP).

This advisory circular provides guidance to customers of the National Airspace System (NAS) in regard to the use of and participation on ATCSCC hotlines.

The new traffic management initiative builds upon concepts found in Ground Delay Programs (GDPs), Airspace Flow Programs (AFPs; AC 90-102A) and required reroutes. The new initiative is called the Collaborative Trajectory Options Program or CTOP.
