Pilot/Controller Glossary

CT MESSAGE- An EDCT time generated by the ATCSCC to regulate traffic at arrival airports. Normally, a
CT message is automatically transferred from the traffic management system computer to the NAS en route
computer and appears as an EDCT. In the event of a communication failure between the traffic management
system computer and the NAS, the CT message can be manually entered by the TMC at the en route facility.
