CS ADR-DSN.J.470 Non-instrument runways ED Decision 2016/027/R (a) The following obstacle limitation surfaces should be established for a non-instrument runway: (1) conical surface; (2) inner horizontal surface; (3) approach surface; and (4) transitional surfaces. (b) The heights and slopes of the surfaces should not be greater than, and their other dimensions not less than, those specified in Table J-1. (c) New objects or extensions of existing objects should not be permitted above an approach or transitional surface except when the new object or extension would be shielded by an existing immovable object. (d) New objects or extensions of existing objects should not be permitted above the conical surface or inner horizontal surface except when the object would be shielded by an existing immovable object, or if after a safety assessment, it is determined that the object would not adversely affect the safety or significantly affect the regularity of operations of aeroplanes. (e) Existing objects above any of the conical surface, inner horizontal surface, approach surface and transitional surfaces should, as far as practicable, be removed except when the object is shielded by an existing immovable object, or if after a safety assessment, it is determined that the object would not adversely affect the safety or significantly affect the regularity of operations of aeroplanes. (f) In considering proposed construction, account should be taken of the possible future development of an instrument runway and consequent requirement for more stringent obstacle limitation surfaces.
