Flight inspection at Frankfurt Airport

Some noise disturbance to be expected

28.09.2015.- Calibration flights will be conducted at Frankfurt Airport between 2300 hrs and 0500 hrs in the night from 3 to 4 October 2015. The accuracy of the satellite-based precision approach system GBAS (Ground-based Augmentation System) will be measured for the southern, centre and northwestern runways. This requires a series of approaches to be made by the calibration aircraft, a Dornier 128-6.

In the period from 8 to 11 October 2015, routine calibration flights will be conducted to measure the accuracy of the instrument landing system (ILS) of the northwestern runway. For these flights, a twin-turboprop Beechcraft Super King Air 350 will be used to fly approaches in both operating directions. During this period, noise disturbance is also to be expected during the night.

If it is impossible to conduct the ILS calibration flights during this period, due to bad weather for example, they will be postponed to the period from 15 to 18 October 2015.

Despite the night curfew at Frankfurt Airport, technical flight checks, such as calibration flights, are permitted at night. During the day, these flights would cause a major disruption to regular air traffic. Please bear in mind that these flights are indispensable for the safety of air traffic. Nevertheless, DFS would like to apologise for any inconvenience caused by such flights.
