Survey flights

in the night of 27 to 28 January

Veröffentlicht: 26. Januar 2023, 11:30 Uhr

The German Air Traffic Control (DFS) has announced new survey flights for the night of 27 to 28 January on the southern runway. Following survey flights in a westerly direction on the night of 21 to 22 January, flights will now take off and land in an easterly direction. In doing so, certain regions can be flown over frequently one after the other and at low altitude, whereby an attempt is made to avoid overflights of settlements as far as the given flight profiles allow. Once again, the Beechcraft Super King Air 350 twin-engine propeller plane will be used.

During the survey flights, the instrument landing system (ILS) of the runway is checked for accuracy and faultless functioning. The specially equipped measuring aircraft checks the precision of the signals required for safe landings. In daily airport operations, the ILS supports the pilots in navigating during the approach. Essentially, this is done by signal transmitters on the ground that send information about the approach course and glide angle to the aircraft's cockpit during landing.

The survey flights take place at night because air traffic does not permit this during the day and the ILS cannot be used operationally during the flight survey. The flights are therefore generally exempt from night flight restrictions. Surveying of the ILS is required by the International Civil Aviation Organisation (ICAO) at regular intervals.
