CS ADR-DSN.J.465 General
Obstacle limitation requirements should be distinguished between:
GM1 ADR-DSN.J.465 General
The requirements for obstacle limitation surfaces are specified on the basis of the intended use of a runway, i.e.
CS ADR-DSN.J.470 Non-instrument runways
The following obstacle limitation surfaces should be established for a non-instrument runway:
GM1 ADR-DSN.J.470 Non-instrument runways
Circumstances in which the shielding principle may reasonably be applied are described in the ICAO Doc 9137, Airport Services Manual, Part 6, Control of…
CS ADR-DSN.J.475 Non-precision approach runways
The following obstacle limitation surfaces should be established for a non-precision approach runway:
GM1 ADR-DSN.J.475 Non-precision approach runways
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…
CS ADR-DSN.J.480 Precision approach runways
The following obstacle limitation surfaces should be established for a precision approach runway Category I:
GM1 ADR-DSN.J.480 Precision approach runways
The following obstacle limitation surfaces should be established for a precision approach runway Category I:
CS ADR-DSN.J.485 Runways meant for take-off
The safety objective of the take-off climb surface slopes and dimensions is to allow safe take-off operations by defining the limits above which new…
GM1 ADR-DSN.J.485 Runways meant for take-off
If no object reaches the 2 % (1:50) take-off climb surface, an obstacle-free surface of 1.6 % (1:62.5) should be established.
CS ADR-DSN.J.486 Other objects
Objects which do not project through the approach surface but which would nevertheless adversely affect the optimum siting or performance of visual or…
GM1 ADR-DSN.J.486 Other objects
In certain circumstances, objects that do not project above any of the obstacle limitation surfaces may constitute a hazard to aeroplanes as, for…
CS ADR-DSN.J.487 Objects outside the obstacle limitation surfaces
Applicability: The specifications in paragraph (b) below apply only to the area under control of the aerodrome operator.
GM1 ADR-DSN.J.487 Objects outside the obstacle limitation surfaces
Beyond the limits of the obstacle limitation surfaces the safety assessment should be conducted for the proposed constructions that extend above the…
