LIMITATION

Division 1 General

7.01 Introduction

       (1) Both of the following must be monitored and maintained free from obstacles in accordance with this MOS:

(a) the airspace around an aerodrome;

(b) the manoeuvring area of an aerodrome.

Note 1   Where the requirement to maintain the OLS and PANS-OPS airspace (protection surface) clear of obstacles cannot be fulfilled, some kinds of aerodrome operation may not be authorised or permitted.

Note 2   An aerodrome operator is responsible for monitoring the OLS and PANS-OPS airspace and must advise CASA in the event of an actual or proposed OLS penetration, and the terminal instrument flight procedure designer in the event of an actual or proposed penetration into the PANS-OPS airspace. Following CASA or designer assessment of any resulting hazard from the penetration, it is the responsibility of the aerodrome operator to advise the relevant planning authority of the result of the assessment and liaise with that authority to ensure that hazardous obstacles that are an unacceptable risk to aviation are not approved; or that hazardous objects or structures are appropriately mitigated, for example, through charting, markings or lighting.

Note 3   Obstacles within the aerodrome boundary are to be dealt with in accordance with section 7.03. To address obstacles either outside of the aerodrome boundary or otherwise outside of the control of the aerodrome operator, may require liaison with the relevant planning authority.

       (2) Obstacle data requirements for terminal instrument flight procedure design must be determined by a certified designer under Part 173 of CASR.

7.02 Obstacle restriction area

       (1) Objects or structures, other than approved visual and navigational aids, must not be constructed or erected within the obstacle restriction area of an aerodrome without the written approval of CASA.

       (2) Equipment and installations required for air navigation must be:

(a) of minimum possible mass and height; and

(b) frangible, including any mountings; and

(c) sited to reduce to a minimum any hazard they may present to aircraft.

       (3) In determining the obstacle clear approach or take-off surfaces, obstacles in the obstacle restriction area must be taken into account.

CHAPTER 7

Division 2 Obstacle limitation surfaces (OLS)

7.03 Introduction

       (1) An aerodrome operator must establish and monitor the obstacle limitation surfaces (OLS) applicable to the aerodrome.

       (2) The physical dimensions of the OLS for approach runways must be determined using Table 7.15 (1).

       (3) The physical dimensions of the OLS for take-off runways must be determined using Table 7.16 (1).

       (4) As far as possible, the aerodrome operator must ensure that the OLS within the aerodrome boundary is maintained clear of obstacles.

Note   If third parties propose to erect structures likely to infringe the OLS outside the aerodrome boundary, it is in the interests of
