摘要： Methods and systems for automatic sequencing of an ownship aircraft behind a lead aircraft on an approach to a runway. The method determines that the ownship aircraft is in an instrument approach. A pilot selection of the lead aircraft is confirmed as matching the lead aircraft identified in an air traffic control (ATC) command. The method includes calculating, an arrival time of the lead aircraft at the runway; processing the arrival time of the lead aircraft at the runway with a desired separation time to determine a target point for the ownship aircraft to merge onto a centerline of the runway; and automatically, and without further human input, generate lateral guidance, vertical guidance, and speed targets for the ownship aircraft to join the runway centerline at the target point at the desired separation time after the lead aircraft.

摘要： A system for detecting ice accretion on a rotor of an aircraft includes a processing system that is configured to: receive torque data indicative of actual torque supplied from an electric motor to the rotor; implement a model of the electric motor and the rotor that determines an estimated torque that should be supplied from the electric motor to the rotor; compute a load on the rotor from the actual torque and the estimated torque; compare the computed load to a predetermined magnitude; and when the computed load exceeds the predetermined magnitude, generate an alert that indicates ice is accreting on the rotor.

摘要： A system and method for detecting yoke interference for an aircraft having an auto pitch trim function is provided. The system includes a source of elevator load data, a source of aircraft speed data, and a processing system. The processing system is coupled to receive the elevator load data, the aircraft speed data, and initial condition center-of-gravity (CG) data that is representative of at least an estimated initial position of the CG of the aircraft. The processing system is configured to process at least the speed data and the initial condition CG data to: (i) determine an expected elevator load on the elevator flight control surface, (ii) determine if the expected elevator load exceeds the sensed elevator load by a predetermined magnitude, and (iii) when the expected elevator load exceeds the sensed elevator load by a predetermined magnitude, generate a disconnect signal that will disable the auto pitch trim function.

摘要： Aircraft and methods of operating the aircraft to provide for increased descent angles. The aircraft includes a fuselage having fixed wings, a horizontal thrust source coupled to the fuselage and configured to selectively generate and supply horizontal thrust to the aircraft, a vertical thrust source coupled to the fuselage and configured to selectively generate and supply vertical thrust to the aircraft, the vertical thrust source including a vertical thrust rotor that is configured to selectively operate in a locked mode, in which the vertical thrust rotor cannot rotate freely in response to contact of airflow therewith, and an unlocked mode, in which the vertical thrust rotor can rotate freely in response to contact of airflow therewith, and a controller configured to selectively supply a command to the vertical thrust source that causes the vertical thrust rotor to operate in the unlocked mode.
