Calibration flights around Frankfurt Airport

In the period from 26 to 30 May 2025, calibration flights will be carried out around Frankfurt Airport. A calibration aircraft specially equipped for this purpose will fly a series of flight procedures.   

The calibration flights will take place during the day, but also at night, depending on the traffic situation.  

Should there be any delays due to technical reasons or the weather, the calibration flights will have to be continued in an alternative period.    

The calibration aircraft being used is a turboprop Beechcraft Super King Air 350. Overflights of built-up areas will be avoided as far as possible and to the extent the specified flight profiles permit. The calibration is to test the safe operation of the approach and departure routes.
