NAS Implementation - Procedures - Localizer Performance (LP)

Localizer Performance (LP) approaches are non-precision approaches with Wide Area Augmentation System (WAAS) lateral guidance. They are added in locations where terrain or obstructions do not allow publication of vertically-guided LPV procedures.

Both LP and LNAV lines of minima are Minimum Descent Altitudes (MDA) rather than DAs. It is possible to have LP and LNAV lines of minima published on the same approach chart. An LP is published if it provides lower minima than the LNAV. See AIM 1-1-20.

Example: RNAV (GPS) RWY 18 at Independence Municipal, Iowa (IIB)
