Embodiments are directed to obtaining a first analog signal corresponding to a position error between a commanded gang output of a plurality of electro-mechanical actuators configured to be run in parallel with one another and a measured gang output of the plurality of electro-mechanical actuators, obtaining a second analog signal corresponding to an output torque, and processing, by a circuit, the first analog signal and the second analog signal to generate and output a discrete that indicates a status of the torque in terms of direction and magnitude.

A personal restraint system configured for use with a seat oriented perpendicular to a direction of flight of an aircraft is provided including a lap portion and a shoulder portion. The lap portion includes a first belt having a belt buckle and a second belt having a belt connector. The first belt is arranged a first side of the seat and the second belt is arranged adjacent a second side of the seat. The belt connector removably couples to the belt buckle. A shoulder portion includes a retractable third belt having a coupling configured to selectively couple to one of the belt buckle and the belt connector. A pretensioner operably coupled to either the first belt or the second belt includes at least one sensor configured to monitor one or more aircraft conditions. Upon detection of a predetermined aircraft condition, the pretensioner applies tension to the first or second belt.

An aircraft is provided and includes a single sensor and wings extending outwardly in opposite directions from a fuselage. Each wing includes a main section, an engine section supported on the main section and tail surfaces extending transversely relative to the main section. The single sensor is mountable to one of the tail surfaces with a field of view (FOV) representable as a spherical wedge having a dihedral angle exceeding 180.

A system and method for determining length of load sling assembly in an aircraft, includes receiving, with a processor, information via one or more sensors regarding a load length during a delivery and descent state, the load length comprising length of a load sling assembly and a load height; controlling, with the processor, a minimum altitude of operation of the aircraft that ensures that the load does not touch the ground or obstacles during one or more of a flight plan, during decent, or during delivery; determining, with the processor, when a load has touched a ground in response to the receiving of the load length information; and releasing, with the processor, the load from the load sling assembly when the processor determines that the load has touched the ground.
