Enhanced Traffic Load Monitor [E-TLM]

E-TLM is an experimental decision support tool developed jointly by ISA Software, AENA and INDRA in support of the Gate-to-Gate Dynamic Re-Sectorisation concept evaluation studies

It is based on the innovative use of Fast-Time Simulation modelling techniques to "fast forward" the current Air Taffic situation in a given ATC centre in order to evaluate the theoretical Controller Workload for a variety of possible sector configurations over the next n-hours (typcially 3-Hours).

Using a highly efficient fast-time ATC simulation model component (based on the ISA Software RAMS Plus ATC modelling engine), a Workload Analysis Component (WAC) derived from "Wickens" cognitive workload evaluation techniques, and interactive updates to current and expected aircraft trajectory (and intent) data, the E-TLM system can evaluate the theoretical workload over the next 3-hour period for each and every possible combination of sectors in an ATC center in a matter of minutes.

Through the E-TLM presentation layer, developed by INDRA, the regional planner (supervisor or potentially the Multi-Sector Planner) receives indications for the most optimal Airspace configuration to satisfy the short to mid-term traffic demand without overloading valuable ATC Controller resources

AENA recently completed their second round of Real-Time, Human in the Loop simulation trials using E-TLM in support of Dynamic Resectorisation at the ATC center in Sevilla, where the E-TLM system was acclaimed to be a highly useful decision support application.
