Question for the Boeing guys, cause I think the fms are somewhat similar. If the ILS is out, and you have no other vertical guidance, can you build or put in a visual with vertical guidance as a reference in the fms? In the CRJ FMS, you can put in a visual approach, keep the needles in white, and have a snow flake to follow to help with vertical guidance on runways with no ils or papi/vasi. Just for situational awareness. Overkill, I know. But I am not chuck Yeager, and my motto in the cockpit is use all available resources to help you out.
