When distribution material is distributed over a target site on a ground surface from an aircraft, a distribution supporting apparatus offers support information to a pilot dropping the distribution material to efficiently distribute the distribution material. The distribution supporting apparatus includes: an input section to which information items on at least an aircraft velocity, an aircraft altitude, and a wind velocity are input; a computation section configured to compute a location at which the distribution material dropped from the aircraft arrives on the ground surface and a density distribution of the distribution material on the ground surface based on the information items input to the input section; and a display control section configured to display, on a display, the support information relating to the location and density distribution computed by the computation section.

Apparatus and method for supporting distribution from aircraft

An aircraft steering angle control system is provided that minimizes the amount of skidding of an airframe that is turning on a low-&#x3bc; taxiway surface, such as an icy taxiway surface, and allows for directional control of the airframe by a steering command. The aircraft steering angle control system outputs an operation signal related to a steering angle as a control command signal for a nose steering wheel, and includes: a nose steering wheel envelope protection function including a reference steering angle setting unit that calculates a reference steering angle on the assumption that the airframe is not skidding; a skid detection unit that detects a skidding state of the airframe based on the reference steering angle; and a switch unit that selects a control command signal for the nose steering wheel in conjunction with the skid detection unit.

Steering angle control system for aircraft

It is an object of the present invention to provide a system that is used to provide support so that a pilot can perform flight operations that reduce noise pollution, by devising this system so that noise conditions on the ground are calculated and displayed on the basis of map information for the flight area in which facilities and the like are described, environmental conditions in the flight area such as the wind direction and wind velocity, or the temperature and density of the atmosphere, and noise generation data for the aircraft itself. The apparatus for supporting low-noise flight according to the present invention comprises means for estimating the noise generated by an aircraft using flight data such as the flight speed, the climb and descent rates, the engine power and the like of the aircraft, means for calculating the level at which the noise generated by the aircraft is propagated in the respective regions on the ground, and means for displaying the calculation results on a map in quantitative terms.
