Are taxiway centre line markings required to extend onto aircraft stands under EASA rules?

No, taxiway centre line markings are not required to extend onto aircraft stands. The guidance clarifies that 'continuous guidance' does not require markings onto stands, but rather on taxiways leading to stands or apron areas where other visual cues (e.g., lead-in arrows, stand number indicators) exist.

What visual cues or other means are mentioned as acceptable alternatives to centre line markings on aircraft stands?

Lead-in arrows and stand number indicators are mentioned as visual cues or other means that can enable aircrew to manoeuvre the aircraft onto a stand or other parking area.

Does GM1 ADR-DSN.L.555 specify any applicability date for its requirements?

No, the section does not state any applicability date.
