Implementing an additional airport / Redesigning airspace to increase flight capacity – LISBON

Home » Use Cases » S1 » Implementing an additional airport / Redesigning airspace to increase flight capacity – LISBON

While demand for flights increased each year, there was limited scope to expand Lisbon’s main airport. NAV Portugal therefore requested our assistance to safely implement a second airport.

Maximising airport capacity

To convert an existing adjacent military airport for commercial flights, NAV Portugal needed to totally redesign the airspace, with additional sectors and a point merge system for arrivals at both airports. The former military airport (Montijo) will be opened for commercial traffic from 2022, although the new airspace design will be used from the end of 2018.

Building a new way of working together

Together we designed a series of simulations to validate the new airspace design. However, staff availability made it impossible for the ATCOs to come to our centre. It was therefore decided to conduct the simulation in Lisbon, on NAV Portugal’s own simulator. To meet this challenge and ensure maximum flexibility, EUROCONTROL and NAV Portugal moved away from standard working practices and opted for a bespoke approach – the EUROCONTROL SIM unit helped prepare real-time simulations on the training simulator at NAV Portugal; the recorded measurements and questionnaire responses were then analysed by us at the EEC.

At a glance

2 simulation sessions:

Phase 1: 5 scenarios, 12 ATCOs, 3 days
Phase 2: Refine scenarios for a 2-week RTS
Result: capacity for 72 movements per hour

“NAV Portugal asked EUROCONTROL to collaborate and assist them in the validation of real time simulation for the redesigned Lisboa TMA that dealt with Point Merge and new SIDs/STARs. This simulation assistance was made for the first time outside EUROCONTROL Experimental Center in Bretigny it has been a fruitful and efficient cooperation between this two entities.”
