approach minimums

LPV

  • does NOT qualify as a precision approach
  • requires WAAS-capable GPS (guidance is similar to ILS)

LNAV/VNAV

  • WAAS not required
  • less precise
  • higher DA for obstacle clearance on a missed approach

LNAV

  • no vertical guidance means the MDA can be lower
  • there may be a steeper angle of descent (closer to the runway)
  • LNAV + V on the GPS display is advisory-only vertical guidance: not the same as WAAS (i.e., "approved vertical guidance"); must use LNAV minimums
