NAV wants ‘exceptional regime’ to run between October 18 – November 29
Portugal’s air traffic control company NAV wants to extend the schedule of nighttime flights in Lisbon due to the implementation of the new Top Sky control system, a company source told Lusa.
Notice for the consultation of interested parties was published on Wednesday to start the procedure to approve an ordinance allowing for an exceptional regime concerning the operation of aircraft at Lisbon airport.
NAV’s official source told Lusa it is a question of extending the schedule of flights in Lisbon for the night period, not increasing the volume of traffic. More a case of “distributing flights over more hours, allowing the air traffic control system to be updated, as of 18 October”.
None of this sounds very clear. Lisbon airport is restricted to 91 flights per week between the hours of 00:00 and 06:00 due to noise.
In July, environmental association Zero stressed that noise levels at Lisbon airport still exceeded legal limits and warned that the night flight restriction regime was also not being complied with.
ZERO cited readings taken in the week beginning July 11, which indicated a total of 140 movements between 00:00 and 06:00.
Thus what NAV’s announcement really means is open to question.
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 until 2023, says Lusa.
Elsewhere, it is described as “the world’s most advanced air traffic control automation solution, designated to control en route, approach and oceanic traffic, both in civil and military environments.”
interested parties – which will include groups like ZERO – now have 10 days to comment on NAV’s request, says Lusa “after which a government decree will enter public consultation and will be known in greater detail”.
