The E-170/175/190/195 has the capability to do VGP approaches. On the E-Jets, it works much like an ILS only the needles are magenta instead of green. The sensitivity remains constant, unlike an ILS, so the course and glideslope don't get squirrelly close to the ground. We (S5) can shoot these approaches using LNAV/VNAV minimums on any compatible RNAV approach.
