What are the Criteria to "upgrade" an Approach from LNAV to LNAV+V?

Most LNAV approaches are eligible for upgrade to LNAV+V.

The Criteria for being Included in the Database are:

  • It must be a GPS-approved approach.

  • There must be a non-zero vertical angle for the approach.

  • A valid geoid height for the runway must exist.

  • The approach does not contain LNAV/VNAV or LPV service levels.

Additionally, the unit must have a SBAS (WAAS, EGNOS, GAGAN or MSAS) signal of sufficient integrity. This means the GPS Status page must show “3D Diff Nav”.

If all these requirements are met, the Garmin navigator will automatically upgrade the approach from LNAV to LNAV+V.
