Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

19.10.2015.- In the period from 22 to 25 October 2015, calibration flights will be conducted at Frankfurt Airport.

The instrument landing systems of the southern runway (easterly weather pattern) as well as the centre runway (westerly weather pattern) will be inspected. A twin-turboprop Beechcraft King Air 350 will be used as the calibration aircraft. During this time, noise disturbance is to be expected both 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 29 October to 1 November 2015.

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.
