APPROACH DESCRIPTION AND INSTRUCTIONS
An LP approach uses SBAS accuracy, similar to an LNAV
approach with more precision, and has lateral accuracy like
an LPV approach. Angular scaling is similar to a localizer
approach. Most LP approaches have step down altitudes
associated with them. The approach still results in an MDA
LP APPROACH
and missed approach point.
The LP+V approach has advisory vertical guidance and at
each step down the pilot must descend to the correct
altitude. The approach results in an MDA and missed
approach point.
