    Abstract: Disclosed is a system for controlling acoustic radiation from an aircraft. The system comprising a plurality of rotor systems (one or more) and a noise controller configured to regulate acoustic radiation from the plurality of rotor systems. The noise controller can be configured to regulate a commanded flight setting from the flight control system and to output a regulated flight setting to the plurality of rotor systems. Based on the regulated flight setting, the plurality of rotor systems are configured to generate, individually and in aggregate, acoustic radiation having a target acoustic behavior. The target acoustic behavior may be achieved using beamforming techniques to, for example, change the directionality of acoustic radiation from the plurality of rotor systems, or otherwise tune the acoustic radiation to reduce detectability and/or annoyance.

    Abstract: A method, apparatus, system, and computer program product for planning multimodal travel. A planning request for the multimodal travel from a first location to an second location is received. Candidate routes are determined for a passenger that is customized for a set of customization parameters a using the first location, the second location, and a set of passenger preferences. A candidate route in the candidate routes comprises a first leg from the first location to a first vertiport via a first modality, a second leg for a passenger air vehicle to travel from the first vertiport to a second vertiport using an air modality, and a third leg from the second vertiport to the second location using a second modality. The candidate route in the candidate routes is selected to form a route for the multimodal travel for the passenger when a user input is received selecting the candidate route.

    Abstract: Disclosed is a system, method, and aircraft for controlling acoustic radiation from an aircraft comprising a plurality of rotor systems and a noise controller configured to regulate acoustic radiation from the plurality of rotor systems. The noise controller can be configured to regulate a commanded flight setting from the flight control system and to output a regulated flight setting to the plurality of rotor systems. Based on the regulated flight setting, the plurality of rotor systems are configured to generate, individually and in aggregate, acoustic radiation having a target acoustic behavior. In certain aspects, the noise controller can change the directionality of acoustic radiation from the plurality of rotor systems, or otherwise tune the acoustic radiation to reduce detectability or annoyance.
