Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

26.02.2018.- In the period from 1 to 04 March 2018, calibration flights will be conducted at Frankfurt Airport.

The accuracy of all instrument landing systems (ILS) for runway northwest will be inspected for both operating directions (easterly and westerly weather patterns). A twin-turboprop Beechcraft King Air 350 will be used as the calibration aircraft. During this time, noise disturbance is to be expected during the day and at night.

If the calibration flights cannot be conducted on these days, for example, due to bad weather, they will be postponed to the period from 8 to 11 March 2018.

Despite the night curfew at Frankfurt Airport, technical inspection flights, such as calibration flights, are permitted at night, as they would have a great impact on regular air traffic during the day.

The calibration of technical facilities is indispensable for the safety of air traffic. DFS would like to apologise for any inconvenience caused by such flights.
