• ED Decision 2016/027/R found in: Aerodromes (139/2014) Part-ADR.AR Part-ADR.OR Part-ADR.OPS CS-ADR-DSN CS-HPT-DSN (Dec 2024)

GM1 ADR-DSN.J.475 Non-precision approach runways ED Decision 2016/027/R (a) If it is of particular importance for safe operation on circuits, arrival routes towards the aerodrome or on departure or missed approach climb-paths, an outer horizontal surface for non-precision approach runways should be established. (b) Circumstances in which the shielding principle may reasonably be applied are described in ICAO Doc 9137, Airport Services Manual, Part 6, Control of Obstacles. (c) Because of transverse or longitudinal slopes on a strip, in certain cases the inner edge or portions of the inner edge of the approach surface may be below the corresponding elevation of the strip. It is not intended that the strip be graded to conform with the inner edge of the approach surface, nor is it intended that terrain or objects which are above the approach surface beyond the end of the strip, but below the level of the strip, be removed unless it is considered they may endanger aeroplanes.
