Edition: 2026-03-03 · In force
34. Two ILS facilities serving opposite ends of a single runway
(1)Where two separate ILS facilities serve opposite ends of a single runway and operationally harmful interference would be present if both facilities were transmitting, an interlock shall be used.(2)The CNS provider shall ensure that the interlock in subregulation (1) allows only the localizer serving the approach direction in use to radiate.(3)The CNS Provider shall ensure that only one facility radiates at a time where two ILS are serving opposite ends of a runway or different runways at the airport using same paired frequencies.(4)When switching from one ILS facility to another, radiation from both shall be suppressed for not less than 20 seconds.(5)At those locations where an ILS facility and a GBAS facility serve opposite approach directions to the same runway, when the approach direction in use is not the direction served by the ILS, the localizer shall not radiate when GBAS low visibility operations that require GBAS Approach Service Type (GAST) D are being conducted, except where it can be demonstrated that the localizer signal supports compliance with the requirements in these Regulations defining the desired to undesired signal ratios and the maximum adjacent channel power tolerable by the GBAS VHF Data Broadcast (VDB) receiver.
