The 4D Trajectory Management - the possibility for Airspace Users to fly preferred route
without reference to the ATS route network. It controls the development of the business or
mission trajectories (BDT to SBT to RBT) in 4 dimensions (latitude, longitude, flight-level
and time).

The
framework
of the 4D
Trajectory
Management
• flexibility, which is in the form of
agreed trajectories provides the safe
and efficient creation, amendment
and distribution of trajectory data;
• cost effectiveness, which provides
an optimal trajectory of flight.

USING FREE ROUTING
1) improved flight efficiency in both fuel efficiency and
business/mission effectiveness;
2)flexibility which offers the airspace users the possibility to
plan their flight trajectories with lots of options;
3)the effectiveness of the environment or fuel efficiency,
allowing to fly with the preferred trajectories and reducing the
distance flown, with reducing flight emissions and fuel burnt.

4D-TRAJECTORY-BASED CONCEPT
Main Benefits of the Business Trajectory:
• Get as close as possible to the user-preferred trajectory (shortest distance /
optimized profile between two points)
• Have a common and shared representation of the flight information
between the aircraft and the ground
• Make the best use of technologies and procedures (FMS, Airlines
Operating Centers, weather prediction…)

Initial 4D operations consist in giving a time constraint at merging point to each
aircraft converging to this point, in order to sequence the traffic.
• Typical merging point could be Initial Approach Fix points, in the vicinity of
congested airports (CTA given before Top of Descent)
• Impact on airborne systems : light avionics upgrade (COM and NAV) with
limited cost
• Impact on airborne systems : Arrival Manager (AMAN) and DL COM
capabilities
The application of initial 4D trajectory operations is improved by the use of the
Airline operational flight plan.
