without NIGS, and drive all the way to clock the jet on bay 19. Now, if the 18A NIGS was on and you were approaching the guidance from the south (so not having even got to the "18" on the ground)... Can't find it now but in the old days we weren't allowed onto the bay without a marshaller or NIGS; "Holding short of bay XX" was a not uncommon refrain.
