Noise disturbance to be expected during the day and at night 

In the period from 24 to 27 April 2014, calibration flights will be conducted at Frankfurt Airport.

The accuracy of the instrument landing system (ILS) for the southern runway (easterly weather patterns) and the ILS for the central runway (westerly weather patterns) 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 this time, due to bad weather for example, they will be postponed to the period from 8 to 11 May 2014.

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.
