In the period from 5 to 7 September 2025, calibration flights to check the instrument landing system (ILS) of the central runway at Frankfurt Airport will be conducted. Operating direction west, i.e. approaches from the east, will be calibrated. A calibration aircraft especially equipped for this purpose will check the precision of the signals, which are essential for safe landings.
On these days, the calibrations will begin at 23:00 hrs and last until approximately 03:00 hrs on the following day. The calibration aircraft being used is a turboprop Beechcraft Super King Air 350. Overflights of built-up areas will always be avoided whenever possible.
The calibration is crucial for the safe, orderly and expeditious handling of air traffic at airports.
