Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

08.06.2015.- In the period from 11 to 14 June 2015, calibration flights will be conducted at Frankfurt Airport.

The accuracy of the instrument landing systems (ILS) for the centre runway, operating direction 07 (easterly weather pattern), and the southern runway, operating direction 25 (westerly weather pattern), will be inspected.

The calibration aircraft being used is a twin-turboprop Beechcraft Super King Air 350. During this time, noise disturbance is to be expected both during daytime and nighttime hours.

In principle, a night curfew applies at Frankfurt Airport from 23:00 to 5:00 hrs and no take-offs or landings are allowed. However, flights for technical checks, such as calibration flights, are also permitted during the night so that there is no negative impact on regular operations 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.
