Abstract: Systems and methods for radar-based aircraft maneuver actions are provided. An example computer-implemented method includes transmitting, using one or more transmitters onboard an aircraft, one or more radio signals. Reflected radio data corresponding to one or more radio signals reflected from a plurality of radio detection and ranging (“radar”) reflectors placed at a plurality of locations associated with an aerial facility can be received using one or more radio receivers onboard the aircraft. A location for the aircraft can be computed based on the radio data and the plurality of locations associated with the aerial facility at which the radar reflectors are placed. A maneuver action for the aircraft can be initiated at a particular landing pad of the aerial facility based on the location.

Abstract: A motor vehicle with an open body which includes forward body columns inclined opposite the driving direction. These body columns are protected against buckling in case of an overturning of the vehicle by approximately vertically extending support struts.

Abstract: In a method of producing blocks of a foamable reaction mixture having an adjustable surface and sharp edges wherein the reaction mixture is discharged from a mixing chamber onto a forwardly moving surface path in a continuous mass of varying height, the improvement therein includes applying forces to the discharging mass opposing formation of differences in the height thereof.
