I have never seen PVD, being a 73 driver. Is it displayed for the T/O runway regardless of nav selections? I'm curious because the 73 EFIS and NG have the ILS needles on the PFD, as long as you select an ILS freq on the nav sources, and the LOC needle will seemingly do the same job. Is it simply a system that gives better peripheral and faster/quicker recognition needed because of the higher cockpits of the wide bodies resulting in greater slant ranges for seeing the runway lighting, given that we would operate to the same departure minima?
