A fly-by-wire (FBW) system comprising a plurality of servo actuators for controlling the flight control surfaces of an aircraft in which each of the servo actuators may comprise a flight control computer (FCC) that controls the output of the servo actuator. Input from a pilot or autopilot system may be communicated directly to the servo actuator FCCs, which may perform the requisite computations to determine the servo actuator output. For each axis, a primary and a secondary servo actuator may be provided, and the secondary servo actuator may operate in the event of a failure in the primary servo actuator. Each servo actuator may have two motors, each configured to drive an end of a differential such that each motor can act as a brake, a clutch or motor on the servo actuator.

Fly-by-wire system with FCC-integrated servo actuators

Autoland systems and processes for landing an aircraft without pilot intervention are described. In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft. The processor can also calculate a merit for each potential destination identified, select a destination based upon the merit; receive terrain data and/or obstacle data, the including terrain characteristic(s) and/or obstacle characteristic(s); and create a route from a current position of the aircraft to an approach fix associated with the destination, the route accounting for the terrain characteristic(s) and/or obstacle characteristic(s). The processor can also cause the aircraft to traverse the route, and cause the aircraft to land at the destination without requiring pilot intervention.

The processor can also cause the aircraft to traverse the route, determine a final approach segment associated with the route; identify terrain characteristic(s) and/or obstacle characteristic(s) associated with the final approach segment; and determine an adjusted final approach segment accounting for the terrain characteristic(s) and/or obstacle characteristic(s).
