LNAV follows Geodetic VS Great Circle
Hi,
Can someone explain to me what's the difference when LNAV follows a Geodetic line compare to great circle tracks?
From my understanding from the descriptions in the web Geodesic path and great circle path are the same in a sphere.
The question rises when I notice some of B737NGs have LNAV provide geodesic guidance and some provide great circle courses.
Regards
