Trajectory-Based Operations (TBO)
Study Team Report
Since the airline, ramp control, and the ANSP want to make a pre-determined takeoff time, ramp
control automation has historical information on taxi-out times, and uses this to calculate a pushback
time that will be part of the flight object. Any delays—loading, maintenance, deicing, etc.—to the
takeoff time are added to the flight object and passed to the ANSP’s strategic evaluation service, and
the surface movement automation is also updated through the flight object change passed from the
strategic evaluation service.

17.6 FBO Flight Management
At many airports that do not have a control tower, there is a FBO that generally provides services for
aircraft. These services include fueling, access to flight plan filing, aircraft maintenance and handling,
and similar support. The FBO is linked to the ANSP through network-centric operations, and can
provide connectivity as a value-added service to pilots, whether in the FBO’s facility or out on the
ramp. The pilot can connect either by cellular phone technology or WiMAX covering the ramp area.
FBO flight management can provide many of the same capabilities as ramp control, allowing the pilot
to connect with changes to their trajectory that then flows to the ANSP’s strategic evaluation
capabilities. Delays can be noted, takeoff times updated, and ETAs changed.

17.7 ANSP Surface Movement Management
Surface movement management is the automation that moves the aircraft from the gate or ramp space
to takeoff within the context of a 3DT (vertical component is not used since all aircraft are on the
surface for this segment of TBO). The surface management function’s purpose is to gain efficiencies in
surface movement and deliver aircraft in the right sequence as close to their planned 4DT takeoff time
as is possible.
Surface movement management is a learning system. Using surveillance from multilateration and
ultimately ADS-B, it remembers throughput, from gate to takeoff and from touchdown to the gate. It
can calculate a nominal taxi time that considers gate, airline, aircraft, time of day, weather conditions,
and other airport operational parameters that affect time (e.g., passing through deicing). The system
learns queue length, throughput, and travel times for combinations of taxi routes that may be assigned
to the aircraft from its gate or runway exit positions. This accumulated information is used to modify
the takeoff times based on expected taxi times for all aircraft.
