Luxembourg’s government announced the news on Tuesday, with transport minister François Bausch saying that the “aerodrome certificate to Lux-Airport is the result of the hard work and excellent cooperation of a large number of people.”

He further said that the goal of the certification was to improve safety. The application process involved a wide-scale verification process to prove compliance.

A total 188 items will have to be rectified during the runway renovation from 2019 to 2020 while 677 organisational and operational requirements had to be fulfilled, and proof supplied that the airport is compliant. An initial appraisal was carried out in April to demonstrate the progress made, the certification audit was done in September and the verification audit in November.

Practical steps to meet the certification requirements included redesign and repainting of surface markings on aprons, taxiways and runway, adaptations and replacement of existing spotlights on the aprons, installation of new mobile light masts, complete resurfacing of the P2 apron, issuing of 2,400 new drivers' licences, introduction of a new airside safety course for all personnel, installation of a new airside inspection team to ensure that the procedures are respected and organising drone flights with very high resolution cameras to record any damages to aprons.

Future renovations will include renewal of the runway, taxiways and aprons and the installation of LED technology on signage panels.
