7.1.4.Equipment placement constraints

7.1.4. Equipment placement constraints System design may require placing remote tower elements, especially cameras and their holding fixtures at the runway strip, taxiway strip, RESA or near the strip of a precision approach runway. For further details on camera placement, see Section 5.2.6. Placing objects inside the runway strip and its corresponding obstacle surfaces is generally prohibited, but Annex 14, Volume 1, Chapter 9.9, on equipment siting, clearly allows equipment inside the runway safety areas if it is needed for air navigation purposes. According to the Chicago Convention nomenclature, the term ‘air navigation’ is equivalent to ATM, and not restrictive to navigation as part of CNS; hence, cameras or other CNS equipment required for air navigation purposes are allowed inside the runway safety areas as well. The applicable EU regulatory framework on aerodromes (CS ADR-DSN.J.480) also allows objects above the inner approach surface, the inner transitional surface or the balked landing surface, provided that they are frangible and because of their function, they should be located on the strip. Furthermore CS ADR-DSN.T.915 stipulating restrictions regarding equipment siting on operational areas allows such installations provided ‘its function requires it to be there for air navigation or for aircraft safety purposes’. Also, GM1 ADR-DSN.B.150 repeats the provisions of Annex 14, permitting placement. Equipment placement should be done taking into account applicable safety and security rules and procedures. When deciding on the most appropriate location, due consideration should be paid to leave the ILS critical/sensitive areas clear. If camera sites are easily accessible to the general public (i.e. outside the aerodrome security area), it should be protected with special care. This should be taken into consideration when developing the physical protection specification, and during implementation and operation. Also Annex 14, Volume I, Chapter 6.1.1 as well as CS ADR-DSN.Q.840, regarding aerodromes that fall within the scope of Regulation (EU) 2018/1139, require objects within the lateral boundaries of the obstacle limitation surfaces to be marked and/or lighted.
