[SA][AA]:  The ACC/Flight Object needs to be enhanced to handle Tower/TRACON controller communications eligibility and handoffs (assuming Tower/TRACON facilities do not have their own FDP).

The FLS function creates, updates, deletes, and distributes Flight Objects. Flight Objects consist of a flight plan, converted route, trajectory, and status information about a flight. Status information includes control eligibility and conformance/adherence status. Requests to FLS are previously syntactically checked; semantic validation is performed by FLS in the process of creating and updating the Flight Object by invoking FPS for the flight plan and RTC for the route.
[from ERAM SADD, Section 4.2.2]

[S1][AA]:  The FLS flight object will need to be updated to include the following information:
- a field indicating that the aircraft is data link capable (may also need to include information about type, version of datalink information - from flight plan??).
- data authority information,
- communications eligibility (note this is different from control eligibility).

[S2][AA]: Additions to the FLS flight object may include:
- FMS Trajectory information

Note: FMS Trajectory information may need to be a new trajectory stored in flight object.  The FMS trajectory might be DIFFERENT from both the Flight Plan Trajectory (ERAM) and the Aircraft Trajectory (ERAM).  The Aircraft Trajectory contains stuff like letters of agreement data that might alter the trajectory that the aircraft is unaware of. 

Note:  The filed flight plan may need to be more detailed to indicate data link type (e.g. ATN, FANS).

The TJS function provides clients with the capability to model trajectories. Services are also provided for deriving the predicted location and time that an aircraft will cross an adapted airspace boundary (e.g. sector, facility) based on the trajectory. Trajectory modeling is
