Description

This Advisory Circular provides guidance to customers of the National Airspace System (NAS) regarding a new traffic management initiative for managing flights through a constrained area. 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. The CTOP is one of many new traffic management initiatives being developed within Collaborative Air Traffic Management Technologies (CATMT) as we progress toward the Next-Generation Air Transportation System (NextGen).
