<strong>Trajectory</strong>-<strong>Based</strong> <strong>Operations</strong> (<strong>TBO</strong>)<br />
Study Team Report<br />
Surface movement management includes the following functions:<br />
• Departures are sequenced <strong>and</strong> staged to maintain throughput<br />
• Lists, by departure <strong>and</strong> arrival runways, are maintained, <strong>and</strong> delays tabulated for departure <strong>and</strong><br />
arrival flows<br />
• Integrated information about weather, departure queues, aircraft flight plan information,<br />
runway configurations, expected departure times, gate assignments, <strong>and</strong> flow information<br />
shared with ramp control <strong>and</strong> airport operations<br />
• Transmission of automated terminal information, departure clearances <strong>and</strong> amendments, taxi<br />
route instructions (including hold-short restrictions for runway crossings) <strong>and</strong> leads to data link<br />
<strong>and</strong> graphical transmission of taxi routes<br />
• Conformance monitoring is provided while taxiing, continuously comparing the route clearance<br />
with surveillance information <strong>and</strong> alerting to non-conformance<br />
• Predict dem<strong>and</strong> <strong>and</strong> plan/manage surface movement <strong>and</strong> arrival/departure flows<br />
• Updates the estimated departure clearance times to renegotiate the 4DT<br />
• Factors in airport operational conditions such as snow removal, aircraft deicing, changes in<br />
runway configuration, <strong>and</strong> effective capacity for the l<strong>and</strong>ing <strong>and</strong> takeoff direction<br />
• Factors in wake vortex separation for both departures <strong>and</strong> arrivals in managing takeoffs<br />
• Identifies slot opportunities for arrivals when the takeoff sequence has holes<br />
• Integrates advanced arrival <strong>and</strong> departure flow management functions to allow ANSP flow<br />
managers to work collaboratively with flight operators to manage high dem<strong>and</strong> situations that<br />
consider various weather <strong>and</strong> airport conditions<br />
• Integrates information from other metroplex airports for time-based departures based on<br />
efficient merging <strong>and</strong> spacing in complex airspace<br />
• Surface movement automation performs runway safety functions supported by surveillance that<br />
enables limited simultaneous runway occupancy for l<strong>and</strong>ing aircraft, defining the safe distance<br />
by review of prior aircraft performance for wet, dry, day <strong>and</strong> night conditions<br />
• Integrates surface movement information to improve controller situational awareness<br />
• Provides a limited capability for surface management at secondary, non-towered airports based<br />
on ADS-B use on the surface<br />
• Provides dynamic, pair-wise longitudinal <strong>and</strong> vertical information for wake turbulence<br />
separation by sequencing aircraft for takeoff<br />
• Supports low-visibility takeoff <strong>and</strong> l<strong>and</strong>ing operations for appropriately equipped aircraft<br />
• Provides a reduced set of functions for remotely staffed tower services <strong>and</strong> automated virtual<br />
towers to sustain the start of a <strong>TBO</strong> for takeoff <strong>and</strong> terminate a <strong>TBO</strong> with l<strong>and</strong>ing<br />
• Information shared from surface movement management, including archived information, is<br />
available for improved strategic management of airside airport infrastructure<br />
• Supports surface movement green operations, limiting noise <strong>and</strong> emissions, <strong>and</strong> gaining taxiout<br />
efficiencies to reduce the environmental footprint of the airport<br />
Throughout surface operations, <strong>TBO</strong> surface movement automation is working to update the 3DT <strong>and</strong><br />
provide to the ANSP strategic evaluation service the necessary updates that coincide with a narrow<br />
takeoff window for the aircraft. Aircraft that must merge with planned overhead traffic have the<br />
tightest window of time. Those departures going to a secondary airport have time measured as an ETA,<br />
<strong>and</strong> do not require tight control. Once the departure sequence is set, progress in terms of time is being<br />
