On a VOR approach, is it legal to have the GPS LNAV/VNAV up to give you guidance with a VOR/ADF bearing pointer up for that approach and fly it that way assuming you put the altitude preselect to MDA. My understanding is yes, as long as that bearing point is in agreement with the GPS needles. My student just bought a G1000 equipped airplane, and I think this is a very valid way to do these approaches even easier/safer. This is how we teach VOR/NDB approaches in the GV/550. Any thoughts on why this wouldn't be an "faa approved" way to do this?
