Introduction to Collaborative Trajectory Options Program (CTOP)

CTOP is a new tool or method of managing demand through constrained airspace while providing flight operators greater control to manage their schedule in regards to both route and delay as defined in their Trajectory Options Set (TOS). Aircraft operators are given greater flexibility with the ability to file multiple flight plan choices in respect to airspace constraints.
