LNAV guidance becomes active at 50 feet AGL under what conditions?

LNAV provides the lateral path along the published approach. It becomes active when you reach 50 feet above the ground on the final approach segment, so the system can reliably track the final approach course and guide you to the runway centerline. This threshold prevents early engagement and ensures you’re stabilized before LNAV starts steering the aircraft laterally. Activation at other altitudes (higher or zero) isn’t how LNAV is designed to engage, and it wouldn’t provide the proper guidance as you near the runway.
