Three questions - how often do they update these markings? And what would park at line 25? And what determines the location of the marking?
I was wondering how often airports/terminals update these markings? Is it strictly done when new aircraft models are expected to arrive (i.e. when the airline announces they are flying say the A380 to an airport they then will paint the marking for it) What would park at line 25? it’s currently blacked out Third- is it the size and reach of the gates that determine where the plane marking is or is it purely dictated by the length of the aircraft?
