The next session of calibration flights concerning the navigation aids at Genève Aéroport will take place from Wednesday 28 April 2021, subject to weather conditions. The operation could go on for three days. Due to the reduced traffic resulting from the Covid-19 pandemic, this spring session will take place during the day.
Subject to weather conditions, the scheduled flight dates are as follows:
- 28, 29 and 30 April 2021 between 12:00 and 18:30.
- Back-up dates: 3, 4 and 5 May 2021
International civil aviation standards require regular checks on the proper functioning and accuracy of airport navigation aids. To this end, a specially equipped aircraft is used to perform a series of approaches.
In Switzerland, calibration flights for navigation aids (Instrument Landing System (ILS) and Very high frequency Omnidirectional Range (VOR)) are carried out under the supervision of Skyguide, the authority responsible for airspace surveillance.
Normally, these calibration flights take place at night with the authorisation of the Federal Office of Civil Aviation because they are likely to disrupt air traffic. Operated during the day, they will therefore create less nuisance.
