Safety assessment concerning simple approach lighting system for precision approaches at airport Münster/Osnabrück

September 2017 | Safety Assessment

With regard to the airport’s infrastructure design there are particular specifications concerning the approach lighting system (ALS) according to EASA CS-ADR-DSN. These directives claim for the compliance of all dimensioning criteria of the ALS pursuant to the approach navigation facilities at the airport. At airport Münster/Osnabrück CAT I and CAT II/III (main landing direction) instrument landing systems (ILS) are installed. According to EASA, ILS CAT I should be operated with a precision approach lighting system (PALS): The PALS should consist of a row of lights on the extended runway centerline extending over a distance of 900 m from the runway threshold. However, at airport FMO there is currently a simple approach lighting system (SALS) with an overall length of 420 m. This aspect was classified as relevant for investigation by the competent authority. Therefore, GfL conducts a safety assessment using methods developed in-house derived from EUROCONTROL’s recommendations. Results will become available by the end of the year.
