Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

26.04.2016.- In the period from 28 to 30 April 2016, calibration flights will be conducted at Frankfurt Airport. They had originally been scheduled for calendar week 16 but due to the weather, it was not possible to conduct all of the required flights.

The instrument landing system of 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 1 May 2016.

In addition, the satellite-based precision approach system GBAS (Ground-based Augmentation System) will be calibrated for the southern runway (westerly and easterly weather patterns) and the northwestern runway (westerly weather pattern). This requires a series of approaches to be made by the calibration aircraft, a Beechcraft King Air 350.

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.
