# GM1 ADR-DSN.B.065 Longitudinal slopes changes on runways

## GM1 ADR-DSN.B.065 Longitudinal slopes changes on runways

(a) Slope changes are so designed as to reduce dynamic loads on the undercarriage system of the [aeroplane](https://avioverse.aero/glossary/easa/aeroplane). Minimising slope changes is especially important on runways where [aircraft](https://avioverse.aero/glossary/easa/aircraft) move at high speeds.

(b) For precision approach runways, slopes in a specified area from the [runway](https://avioverse.aero/glossary/easa/runway) end, and including the touchdown area, are so designed that they should correspond to the characteristics needed for such type of approach.
