Stop Bars in Hong Kong
Regarding stop-bars here, we have limited stop-bars associated with taxiways but all holding positions for all entry to both runways have stop-bars in accordance with ICAO requirements. Whenever the viz is down to 6km and/or the cloud ceiling is less than 1,000 feet, at night or whenever ATC consider it may assist pilots, approach & runway lights shall be switched on & the stop-bar lights should be switched on when approach lighting is switched on. In any case all stop-bars switch on automatically when the pre-set lighting for CAT I / CAT II / CAT III lighting is selected. To repeat, ALL entry points to both runways have stop-bars. Hope that answers your question.
