A method of guidance for an aircraft includes obtaining relative position data indicative of a direction from a location of the aircraft to a location of a moving target point. The method also includes determining, based on the relative position data, a location of a virtual leader based on projecting the location of the aircraft onto a virtual leader path, where the virtual leader path corresponds to a straight approach path to the location of the moving target point along a desired approach direction. The method further includes determining, based on the location of the virtual leader, a guidance input to cause the aircraft to follow the virtual leader.

Autoland systems and processes for landing an aircraft without pilot intervention are described. In implementations, the autoland system includes a memory operable to store one or more modules and at least one processor coupled to the memory. The processor is operable to execute the one or more modules to identify a plurality of potential destinations for an aircraft. The processor can also calculate a merit for each potential destination identified, select a destination based upon the merit; receive terrain data and/or obstacle data, the including terrain characteristic(s) and/or obstacle characteristic(s); and create a route from a current position of the aircraft to an approach fix associated with the destination, the route accounting for the terrain characteristic(s) and/or obstacle characteristic(s). The processor can also cause the aircraft to traverse the route, and cause the aircraft to land at the destination without requiring pilot intervention.

An aircraft emergency oxygen supply system includes: at least one passenger oxygen mask; a compartment for housing the at least one passenger oxygen mask; and at least one oxygen hose. E each of the at least one passenger oxygen mask is coupled to a respective oxygen hose for supplying a gas comprising oxygen to the respective oxygen mask; at least one fixing clip. Each of the at least one fixing clip comprises a lanyard fixing portion and at least one C-shaped oxygen hose fixing portion for releasably holding one or more oxygen hoses. For each of the at least one fixing clip, the aircraft emergency oxygen supply system comprises a lanyard having a first end, which is fixed at the compartment, and an opposing second end, which is fixed to the lanyard fixing portion of the respective fixing clip.

Provided is a drone with an airbag with which it is possible to prevent the danger of injuring a person when a crashed drone collides with the person. A first airbag 11 is provided in a state surrounding a drone 9 within the horizontal plane. The first airbag 11 is held by a first holding part 10 provided on a central mounting part 2. The first airbag 11 is installed in the first holding part 10 in a folded state, the first airbag 11 being inflatable so as to project outward by gas being supplied. The first airbag 11 is capable of expanding before impacting another object such as a person and surrounding the drone 9 in the horizontal plane.

An improved system detects an environmental anomaly in a shipping container and initiates a mediation response through a generated layered alert notification. The system includes sensor-based ID nodes associated with packages within the container, and a command node mounted to the container communicating with the ID nodes and an external transceiver on a vehicle transporting the container. The command node is programmed to detect sensor data from the ID nodes; compare the sensor data to package environmental thresholds in context data related to each ID node; detect the environmental anomaly when the comparison indicates an environmental condition for at least one package exceeds its environmental threshold; responsively generate a layered alert notification identifying a mediation recipient and mediation action, and establishing a mediation response priority based upon the comparison; and transmit the layered alert notification to the transceiver unit to initiate a mediation response related to the mediation action.

A method of fire suppression may include injecting a reactive agent into a reaction zone to produce a catalytically active species for fire suppression and conveying the catalytically active species to a fire to catalytically interfere with flame chemistry of the fire. Fire in a fuel tank may be suppressed by injecting the reactive agent into a convective flow of a mixture of fuel and oxidizer in a fuel tank, the reactive agent reacting in the fuel tank to release a species which catalytically interferes with flame chemistry to suppress fire in the fuel tank. Fire at an airplane crash may be suppressed by releasing the reactive agent from the container at the crash site to produce an active species to catalytically interfere with a fire at the crash site.
