Pursuant to section 10(a) (2) of the Federal Advisory Committee Act: (Pub. L No. 92-463, 5 U.S.C. App.) notice is hereby given for an Industry Day meeting to introduce the Four Dimensional Trajectory Demonstration (4DT) project to the aviation community.


○ The 4D Trajectory Demonstration Project will conduct a demonstration of the key 4DT Trajectory Based Operations (TBO) services, including Dynamic Required Navigational Performance (DRNP), Advanced Interval Management (AIM), and Air Traffic Control (ATC) Winds. It will also demonstrate the use of Aeronautical Telecommunication Network (ATN) Baseline 2 data link for the exchange of 4D Trajectories between ground automation systems and aircraft to exercise TBO concepts.

○ The purpose of the project is to demonstrate the technical feasibility and evaluate benefits of the advanced TBO services enabled by modern data link technologies. The 4D Trajectory demonstration will leverage the availability of ATN baseline 2 data link standards, advanced Performance Based Navigation (PBN) and surveillance avionics suites, common flight object for trajectory exchange between Air Traffic Management (ATM) automation and Flight Operations Center (FOC) automation.


○ Attendance is open to the interested public but limited to space availability and is on a first come, first serve basis. A webcast will be provided for those who cannot attend in person. To attend the Industry Day (in person or via webcast), participants must register via the following link:​e/​4dt-demonstration-industry-day-tickets-16997639397
