8.6.1 General

Note1 - Requirements for obstacle limitation surfaces are specified in 4.2.

Note2 - The design of light fixtures and their supporting structures, light units of visual approach slope indicators, signs, and markers is specified in 5.3.1, 5.3.6, 5.4.1 and 5.5.1, respectively. Guidance on the frangible design of lights and other navigation aids is given in the ICAO Airport Services Manual, Part6.

8.6.1.1 Standard - Unless its function requires it to be there for air navigation purposes, no equipment or installation shall be:

  1. on a runway strip, a runway end safety area, a taxiway strip or within the distances specified in Table3-1, column4, if it would endanger an aircraft; or
  2. on a clearway if it would endanger an aircraft in the air.

8.6.1.2 Recommendation - Any equipment or installation required for air navigation purposes which must be located in an area identified in 8.6.1.1, should be regarded as an obstacle and should be of minimum practicable mass and height, be frangible, and sited in such a manner as to reduce the hazard to aircraft to a minimum.

8.6.1.3 Standard - Any equipment or installation required for air navigation purposes which must be located on or near a strip of a precision approach runway and which:

  1. is situated on that portion of the strip within:

    1. 60 m of the runway centre line where the code number is 3 or 4; or
    2. 45 m of the runway centre line where the code number is 1 or 2; or
  2. penetrates the take-off/approach surface or the inner transitional surface; shall be of minimum practical mass and height, be frangible, and sited in such a manner as to reduce the hazard to aircraft to a minimum.

8.6.1.4 Recommendation - Any equipment or installation required for air navigation purposes and which is an obstacle of operational significance in accordance with 4.2.2.7, 4.2.3.5 or 4.2.4.6, should be of minimum practicable mass and height, be frangible, and sited in such a manner as to reduce the hazard to aircraft to a minimum.
