Flight inspection at Frankfurt Airport

Noise disturbance to be expected at night as well

21 October 2013 - In the period from 24 to 27 October 2013, calibration flights will be conducted at Frankfurt Airport.

Both the instrument landing system of the southern runway (easterly weather pattern) as well as the central runway (westerly weather pattern) will be inspected. A twin-turboprop Beechcraft King Air 350 is being used as the calibration aircraft. During this time, noise disturbance is to be expected both during day- 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 31 October to 3 November 2013.

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