Abstract: Diverse types of crew interfaces (400, 430, 450) are provided for outputting visible, audio and tactile information to a pilot for flight control. A unified estimation of the current aircraft state and of a current phase of flight are made (110), based on flight status information. Respective coordinated visible, audio and tactile presentations for the diverse types of crew interfaces are generated, (120) coordinated so that they provide mutually consistent indications of the unified estimation of the current aircraft state, according to the unified estimation of current flight phase. The respective coordinated presentations are output (130) by the diverse types of crew interfaces to the pilot. By coordinating crew interface outputs across sight, sound and touch senses, this can relieve the pilot of workload in interpreting unsynchronised or incoherent outputs from different types of interfaces.

Abstract: A method to autonomously taxi an aircraft is disclosed. The method comprises receiving, by a processing means, a route intended for the aircraft 310. Obtaining, by the processing means, a route line based on the route 320. Determining, by the processing means, at least one route feature along the route line 330. Determining, by the processing means, a deviation of a nosewheel of the aircraft from the route line based on a current position of the aircraft provided by the aircraft global navigation satellite system (GNSS) 340. Outputting, by the processing means, an adjustment of an angle of the nosewheel to correct the deviation from the route based on the deviation of the nosewheel 350. Outputting, by the processing means, an adjustment of the speed of the aircraft based on a current position on the route line and a proximity to the at least one determined route feature 360.
