GM1 ADR.OPS.B.065 Visual aids and aerodrome electrical systems ED Decision 2021/003/R UNSERVICEABILITY OF STOP BARS In situations where the stop bars cannot be turned off because of a technical problem, the following contingency measures may, inter alia, be considered: (a) physically disconnecting the respective lit stop bar from its power supply; (b) physically obscuring the lights of the lit stop bar; and (c) using a different route, until the malfunctioning system has been repaired. In case of implementation of (a) or (b), a marshaller or a follow-me vehicle may need to be provided to lead the aircraft to cross the stop bar. Moreover, in case of implementation of (b), care is necessary to ensure correct implementation of the measure to avoid misunderstandings by the flight crew. In any case, the measures taken do not undermine the principle that a lit stop bar must not be crossed, while maintenance action needs to be taken as soon as possible.
