The A321 uses LNAV/VNAV for what?

Explanation:
LNAV/VNAV is a navigation mode that provides both lateral and vertical guidance, allowing the aircraft to fly a published 3D path to the runway. On the A321, enabling LNAV/VNAV lets the autopilot and flight director follow a designed lateral route (left/right) and a vertical descent path (up/down) using GPS/RNAV data. This is used for approaches that publish a vertical guidance profile, sometimes called APV, guiding you down to a DA/DH with the proper descent angle rather than just following a horizontal track. It’s not about holding a pattern, avoiding weather, or controlling engines, so those functions are separate.
