A system for electric aircraft navigation includes a sensor configured to detect a navigation signal, a flight controller, wherein the flight controller is configured to receive the navigation signal, identify a navigation status as a function of the navigation signal, and determine an aircraft adjustment as a function of the navigation status, and a pilot display, wherein the pilot display is configured to display the aircraft adjustment to a user, and present an autonomous function configured to enact the aircraft adjustment automatically.

An apparatus for visual navigation of a UAV includes a geo-fiducial mat and a plurality of geo-fiducials. The geo-fiducial mat includes a landing pad region that provides a location for aligning with a landing pad of a UAV and a survey point. The geo-fiducials are each specified for a unique directional and offset position in or about the landing pad region relative to the survey point. The geo-fiducials each includes a two-dimensional (2D) pattern that visually conveys an alphanumerical code. The 2D pattern has a shape from which a visual navigation system of the UAV can visually triangulate a position of the UAV.

A system and method for conducting preflight planning for autonomous flight missions of unmanned aerial vehicles (UAVs). The system includes use of a controller to conduct quantitative risk assessments of available digital data to predict low risk flight routes based on estimated flight risk profiles. The flight risk profiles may be based upon flight safety-critical information, including real time regulatory, airspace, obstacle, and infrastructure data sets. Among other data sets, the flight risk profiles may also account for current weather, current population and traffic data, and aircraft operational data specific to the UAV involved. Each risk assessment can generate a flight risk profile dependent on proposed times of travel, from which a low risk route may be predicted for any impending autonomous aircraft flight. Such risk assessments may enhance chances of expeditious regulatory acceptance of flight plans for such predetermined flight routes.

A system and method for pilot assistance in an electric vertical takeoff and landing (eVTOL) aircraft. The system generally includes a pilot control and a flight controller. The pilot control is attached to the eVTOL aircraft. The pilot control is configured to transmit an input relating to the flight path of the aircraft. The flight controller is communicatively connected to the pilot control. The flight controller is configured to receive the input relating to the flight path, generate an output of a recommended flight maneuver as a function of the input, and display the recommended flight maneuver.

Systems and methods provide dynamically modifiable parameters in required time of arrival (RTA) speed regions of an assigned flight path of an aircraft. The system includes a vertical situation display (VSD) rendering thereon a vertical flight profile of the assigned flight path. A control module is coupled to the display system and configured to: demark the vertical flight profile with a plurality of RTA speed regions related to an initial speed profile; render an RTA speed band graphic having demarked sections vertically representing a speed minimum and speed maximum for an respective RTA speed region, the RTA speed band graphic representing a normalized speed range between zero and a maximum value for each respective RTA speed region. The control module accepts user modifications and updates the RTA speed band graphic and the current speed profile to reflect user input.

In some examples, an unmanned aerial vehicle (UAV) may receive location information via the global navigation satellite system (GNSS) receiver and may receive acceleration information via an onboard accelerometer. The UAV may determine a first measurement of acceleration of the UAV in a navigation frame of reference based on information from the accelerometer prior to or during takeoff. In addition, the UAV may determine a second measurement of acceleration of the UAV in a world frame of reference based on the location information received via the GNSS receiver prior to or during takeoff. The UAV may determine a relative heading of the UAV based on the first and second acceleration measurements. The determined relative heading may be used for navigation of the UAV at least one of during or after takeoff of the UAV.

A method for determining transition height elements in a flight climbing stage based on constant value segment identification comprises the steps of splitting a speed component and a Mach component from a flight track, and performing linear interpolation on the two respectively; discretizing the interpolated speed component, and setting a threshold for filtering to obtain a speed discrete value set; identifying a constant-speed segment, and acquiring a maximum constant-speed value and a maximum moment of the constant-speed segment; keeping the Mach component of the track with a time no less than the constant-speed maximum moment; discretizing the kept Mach components, and filtering to obtain a Mach discrete value set; identifying a constant-Mach segment, and acquiring a constant-Mach value corresponding to a minimum moment of the constant-Mach segment; and calculating a transition height in the flight climbing stage according to the constant-speed value and the constant-Mach value obtained.

A method and a system for establishing a route of an unmanned aerial vehicle are provided. The method includes identifying an object from surface scanning data and shaping a space, which facilitates autonomous flight, as a layer, collecting surface image data for a flight path from the shaped layer, and analyzing a change in image resolution according to a distance from the object through the collected surface image data and extracting an altitude value on a flight route.

A method of assisting in piloting an aircraft having a fuselage, the aircraft having a first side arrangement and a second side arrangement, which arrangements are disposed laterally on either side of the fuselage, and each of them participates in the movement of the aircraft. During an assistance phase, the method includes the following steps: measuring a value of a first ground clearance of the first side arrangement and a value of a second ground clearance of the second side arrangement; and displaying on a screen at least one symbol that varies as a function of the variation in the value of the first ground clearance and/or of the variation in the value of the second ground clearance.
