Flight inspection at Frankfurt Airport

Flights take place at night as well

21.08.2017.- In the period from 24 to 27 August 2017, calibration flights will be conducted at Frankfurt Airport.

The accuracy of the 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 daytime and nighttime hours.

If it is impossible to conduct the calibration flights during the planned period, for example due to bad weather, they will be postponed to the period from 15 to 17 September 2017.

Despite the night curfew at Frankfurt Airport, technical flight checks such as calibration flights may also be conducted 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.
