The FAA/Airline Data Exchange (FADE) experiment determines whether updated
schedule information from NAS users affects Traffic Flow Management’s
decision making.

August - ATCSCC exercises the CDM concept in preparation for operational
exercises.
Human-in-the-loop exercises result in a total reduction of 10-40% of assigned
airline delay.
December -
A joint airline/ATCSCC exercise is conducted at Metron, Inc in Reston,
Virginia to measure the combined effects of improved decision making and
the new compression process. Total delay reduction is 10-35% depending
upon the airport and scenario.

Spring - CDM
"Roles and Responsibilities"
