The Enhanced tactical flow management system (ETFMS) provides enhanced tactical data to all operational stakeholders, regardless of national boundaries, language, or equipment. ETFMS facilitates improvements in flight management from the pre-planning stage to the arrival of the flight. It maximises the updating of flight-related data and thus improves the real picture of a given flight, thereby contributing to the gate-to-gate concept.
The ETFMS has two main functions:
- Calculation of traffic demand in every sector of the NM area of operations, using the flight plan information received from the aircraft operators (AOs) via the initial flight plan processing system (IFPS);
- Computer-assisted slot allocation (CASA) – a more complex calculation, slot allocation and distribution of the resulting lists to all parties involved.
