A passenger service unit is provided. The passenger service unit includes at least one projector configured to project an image onto one or more display surfaces, at least one sensor configured to indicate a current position of the one or more display surfaces, and a projector controller in communication with the at least one projector and the at least one sensor. The projector controller is programmed to receive a signal from the at least one sensor indicating a current position of a display surface and instruct the at least one projector to project at least one image onto the tray table based on the current position of the display surface.

Herein provided are methods and systems for assessing a fuel burn level of an aircraft for a planned mission. Flight information relating to the planned mission is obtained via a graphical user interface, the flight information comprising configurable number of passengers for the aircraft. A requisite engine bleed level for the planned mission is determined based on the flight information. The fuel burn level is assessed based on the requisite engine bleed level.

A control system for an aircraft cabin includes a first sensor, a second sensor, and a processor. The first and second sensors are configured to detect communicative gestures of a subject and are oriented to detect the communicative gestures in first and second cabin volumes, respectively. The second cabin volume at least partially overlaps the first cabin volume. The processor is configured to: identify a control volume defined by an overlap between the first and second cabin volumes; define a task envelope as a sub-set of the control volume in which the subject may perform the communicative gestures; disregard communicative gestures outside of the task envelope; compare an identified gesture of the communicative gestures performed inside the task envelope with a plurality of stored gestures; and generate a control task to command cabin devices in response to a match between the identified gesture one of the stored gestures.

Introduced here are technologies for examining an image of an airline passenger, while the passenger is onboard. The image may be examined for abnormalities, the passenger's mood, and/or the passenger's expression. The image analysis may be supplemented by data from a suite of sensors such as heart rate monitors, accelerometers, gyroscopes, and the like. The image and the sensor data are then analyzed to detect abnormalities, identify related recommendations, and suggest products and services offered onboard or at the destination that are related to the abnormalities and recommendations. The general purpose is to improve an airline passenger's travel experience while on board the flight.

A seatbelt detection system detects seatbelt use in each seat of a passenger aircraft to produce safety-compliance data. A computer system, which is communicatively coupled to the seatbelt detection system, receives sensor data from a plurality of sensors in an aircraft cabin; and employ an artificial intelligence (AI) program to train on input data comprising at least one of safety compliance data, aircraft system data, cabin environment data, cabin operations data, or aircraft operations data; and the AI program is configured to minimize a summed error of predictions of seatbelt compliance.

An aircraft projection device includes a projector that displays an image by projecting the image onto a floor surface of a passage in an interior of an aircraft; and a controller that controls the projector to display the image onto the floor surface of the passage in the interior of the aircraft.

According to some examples of the presently disclosed subject matter there is provided a system and method for deploying a plurality of unmanned aerial vehicles (UAVs) by an airborne carrier aircraft for dispersing payload material, each UAV comprising at least one container containing payload material and being configured to disperse the payload material at a designated dispersion area in an event site.

A device having at least one communication unit arranged in a wall of the aircraft and at least one communication unit arranged in a seat of the aircraft, which are able to cooperate with one another in order to communicate data by means of visible light. The device also includes at least one inductive transmitter arranged in the wall and at least one inductive receiver arranged in the seat, which are able to cooperate with one another in order to transmit electric power by induction. Also a system with such a device and an aircraft with such a device or such a system.

A cabin attendant aircraft tray table may include a front section of a body, a rear section of the body, and at least one hinge coupling the front section and the rear section. The front section may be configured to actuate relative to the rear section via the at least one hinge between a stowed position, a personal electronic device (PED) position, and a tray position. The cabin attendant aircraft tray table may be stowable in a cavity defined within a frame of a cabin attendant aircraft seat assembly when the front section is in the stowed position. The front section may be held in place relative to the rear section via a mechanical assembly when the front section is in the PED position, and may be configured to receive and support a PED when the front section is in the PED position.
