Abstract

A craft comprises a hull, a wing, a hydrofoil, and a control system. The wing is configured to generate upwards aero lift as air flows past the wing to facilitate wing-borne flight of the craft.

Abstract

While hull-home and operating in a heading adjustment mode, the control system of the disclosed craft receives indications of a target craft heading and an observed craft heading. Embodiments include determining that the difference in heading is above a threshold, determining an adjusted wing-affixed control setting for affecting a change in the observed heading of the craft based on at least (a) sensed environmental conditions, (b) the initial wing- affixed control setting, (c) the target craft heading, and (d) the observed craft heading; and operating wing-affixed control element(s) according to the adjusted wing-affixed control setting to change the observed heading of the craft to the target craft heading. After determining that the heading difference is not above the threshold heading difference, the wing-affixed control setting is adjusted to forgo affecting further change in the observed heading of the craft.
