Aviation Glossary :: LNAV/VNAV  Aviation Glossary :: LNAV/VNAV FAA Written Test Preparation
Aviation Glossary Welcome to the Dauntless Aviation Glossary!

At Dauntless, our editorial staff maintains the web's largest unified glossary of aviation terms. This glossary is built from a combination of official, quasi-official, and proprietary sources (including original material that we develop oursselves). Uniquely, we often provide multiple definitions of a given term so that you can find that which best applies to you. In order to maximize your learning efficiency, this glossary (and similar ones for our international users) is incresingly fully integrated into our aviation learning apps, including our FAA written test prep and FAA practical test prep software and apps. If you like this glossary, you'll love them with their polished learning environments and world's best and clearest content (please do give them a try.).

LNAV/VNAV
LNAV/VNAV
Lateral navigation/vertical navigation minimums provided for RNAV systems that include both lateral and vertical navigation (e.g., WAAS avionics approved for LNAV/VNAV, certified barometric VNAV with IFR approach certified GPS). Procedure minimums altitude is published as DA (decision altitude).
source: FAA Advanced Avionics Handbook (FAA-H-8083-6)
Identifies APV minimums developed to accommodate an RNAV IAP with vertical guidance, usually provided by approach certified Baro-VNAV, but with lateral and vertical integrity limits larger than a precision approach or LPV. LNAV stands for Lateral Navigation; VNAV stands for Vertical Navigation. These minimums can be flown by aircraft with a statement in the Aircraft Flight Manual (AFM) that the installed equipment supports GPS approaches and has an approach-approved barometric VNAV, or if the aircraft has been demonstrated to support LNAV/VNAV approaches. This includes Class 2, 3 and 4 TSO-C146 WAAS equipment. Aircraft using LNAV/VNAV minimums will descend to landing via an internally generated descent path based on satellite or other approach approved VNAV systems. WAAS equipment may revert to this mode of operation when the signal does not support “precision” or LPV integrity. Since electronic vertical guidance is provided, the approach minimum altitude will be published as a decision altitude (DA).
