Abstract: There is disclosed a rotorcraft comprising: an array of lift devices; a pilot housing; connecting lines attaching the pilot housing to the array of lift devices; and an actuator interface at the pilot housing such that the pilot can 5 steer the rotorcraft.

Abstract: There is disclosed a rotorcraft comprising: an array of lift devices supported at a structure; a first group of the lift devices configured to generate thrust in a first common direction; a second group of the lift devices being tilted or tiltable relative to the first group of devices so as to generate thrust in at least a second common direction; and a flight control system.

Abstract: Disclosed is a glide path indicator (2) comprising a light emitter (20) configured to emit a visible light signal that defines a glide path (14) for use by a pilot of an approaching aircraft (10), and a camera (22) configured to capture images of the approaching aircraft (10), the camera (22) being arranged such that at least part of the glide path (14) defined by the light emitter (20) is located within a field of view of the camera (22). The glide path indicator (2) may be mounted to a vehicle (4), for example, an aircraft carrier. The glide path indicator (2) may further comprise a stabilization module (26) configured to stabilize the light emitter (20) and the camera (22) so as to reduce or eliminate the effects of the vehicle's motion on the glide path (14) and the field of view of the camera (22).
