Flight inspection at Frankfurt Airport

Noise disturbance to be expected during the day and at night

08.04.2013.- In the period from 11 to 14 April and from 25 to 28 April 2012, calibration flights will be conducted at Frankfurt Airport.

In the first period (11 to 14 April), the precision of the instrument landing systems of the northern runway will be inspected. Flight checks will be conducted for the landing directions 25 (westerly weather patterns) and 07 (easterly weather patterns).

If it is impossible to conduct the calibration flights during the planned period, for example due to bad weather, they will be postponed to the period from 18 to 21 April 2013.

In the second period (25 to 28 April), the precision of the instrument landing systems of the central runway will be inspected. Flight checks will be conducted for the landing directions 25 (westerly weather patterns) and 07 (easterly weather patterns).

The alternative period for this second period will be from 2 to 5 May 2013.

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

Despite the night curfew, technical flight checks such as calibration flights may also be conducted at night as they would have an immense impact on regular air traffic 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.
