What does the VS/PATH wheel provide if VS is not selected?

The VS/PATH wheel is an essential control feature in the Dassault Falcon 7X, and when vertical speed (VS) is not selected, it allows the pilot to set and manage a PATH target. This PATH target corresponds to a calculated optimal vertical flight path to maintain or to achieve a predetermined altitude with specific atmospheric conditions in mind.

When managing descent, having a PATH target enables the crew to follow a designated trajectory, which is particularly useful in achieving smooth and efficient descents. In contrast to vertical speed targets or altitude targets that focus on specific rates of climb or descent or on reaching a preset altitude, the PATH target prioritizes maintaining a trajectory influenced by various factors including airspeed, flight profile, and environmental conditions.

Thus, utilizing the VS/PATH wheel in this manner ensures that the aircraft remains on a desirable path, aligned with performance requirements and safety considerations during flight operations.
