Air traffic controller NAV wants to extend the timetable of flights in Lisbon, for the night period, between October 18 and November 29, due to the implementation of the new Top Sky control system, a company source told Lusa.

An official source from NAV explained to Lusa that it is about extending the timetable of flights in Lisbon, for the night period, not to increase the volume of traffic, but to spread the flights over more hours, thus allowing the update of the air traffic control system, from 18 October. The idea is that the exceptional regime will be in force between October 18 and November 29, explained NAV.

Lisbon airport has a night flight restriction regime, which sets a limit of 91 weekly flights between 00:00 and 06:00, due to noise. In July, the environmental association Zero denounced that noise levels at Lisbon airport exceed legal limits and warned that the night flight restriction regime is also not complied with, citing measurements taken in the week starting July 11 and which pointed to a total of 140 movements between 00:00 and 06:00.

The Top Sky project, common to six other countries and coordinated by Eurocontrol, was presented by NAV in 2019 and foresees an investment of 103.8 million euros, until 2023.
