I don't have the information...does anyone know if the runway the landing was attempted on has ALSFII...or what kind of approach lights? sequenced flashers/rabbit?
anyway, in the USA...at DA/DH if you have JUST the sequenced flashers in sight you may descend to TDZE plus 100'...at that time you must have the many items we used to call the runway environment in sight to continue to landing.
Does Ireland have that rule?
