Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

13.10.2014. -In the period from 24 to 26 October 2014, calibration flights will be conducted at Frankfurt Airport.

The accuracy of the instrument landing systems (ILS) for the centre runway (westerly weather patterns) and the northwest runway (easterly weather patterns) 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 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 30 to 2 November 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.
