Lateral Navigation(LNAV)
Definition
GPS-based lateral guidance for non-precision approaches. LNAV approaches use a minimum descent altitude rather than decision altitude. LNAV/VNAV adds vertical guidance from baro-VNAV or SBAS.
Why Lateral Navigation Matters for Pilots
Navigation concepts like Lateral Navigation are tested on instrument rating exams and are essential for safe cross-country flying. Whether you are planning a VFR flight or navigating under IFR, a solid understanding of Lateral Navigation ensures you can find your way accurately and efficiently.
Exam Tip
This concept is commonly tested in navigation-related questions on FAA and EASA exams. Make sure you can explain Lateral Navigation in your own words for the oral exam. Practice applying this concept to real-world scenarios, not just memorizing the definition.
