Surveying flights

during the night of 11 to 12 April

Published: 09 April 2025, 15:00

German air traffic control (DFS) has announced that it will conduct aerial surveys on the northern runway of BER during the night of 11 to 12 April. A relatively quiet, twin-engine, propeller-driven aircraft of the type Beechcraft Super King Air 350 will be used. During the calibration flights, the aircraft will take off and land in an easterly direction, frequently flying over certain regions in succession and at low altitudes. Overflying of populated areas will be avoided as far as the prescribed flight profiles allow.

During the survey flights, the instrument landing system (ILS) of the runway is checked for accuracy and error-free operation. The ILS supports pilots in their daily flight operations during navigation during the approach. This is mainly done by signal transmitters on the ground that send information about the approach course and glide angle to the cockpit of the aircraft during landing.

The specially equipped measuring aircraft checks the precision of the signals required for safe landings. As usual, the survey flights take place at night, as air traffic does not permit this during the day and the ILS cannot be used during the flight inspection. The flights are therefore generally exempt from night flight restrictions.

The International Civil Aviation Organisation (ICAO) requires that the ILS be measured at regular intervals.
