Schematic display for vertical navigation
First Claim
1. A method for presenting vertical navigation (VNAV) data on an aircraft, the method comprising:
- dividing a flight plan into a series of VNAV legs based on vertical waypoints in the flight plan, each VNAV leg of the series of VNAV legs including exactly one of;
a top of climb (TOC) vertical waypoint or a top of descent (TOD) vertical waypoint;
generating a series of profile-view schematics, each profile-view schematic of the series of profile-view schematics corresponding to one VNAV leg of the series of VNAV legs;
identifying an active VNAV leg among the series of VNAV legs based on a location of the aircraft with respect to the series of VNAV legs; and
displaying an active profile-view schematic that corresponds to the active VNAV leg.

Abstract
A schematic display for presenting vertical navigation (VNAV) data is disclosed. A planned route such as a flight plan is divided into a series of VNAV legs, and only a VNAV schematic that corresponds to the active VNAV leg is displayed. The VNAV schematic in accordance with the present disclosure is a profile-view schematic for the active VNAV leg, providing a visual representation indicating the locations of the upcoming Top of Climb (TOC) or Top of Descent (TOD). Additional VNAV data may also be presented to provide content context. Since the schematic display in accordance with the present disclosure only displays VNAV data relevant to the active VNAV leg at a given time, the complexities associated with displaying the VNAV schematic is reduced, making the VNAV data easy to read and understand.
