Collision with ground / water / terrain and midair obstacles is one of the common causes of severe aircraft accidents. The various data from the coremicro AHRS / INS / GPS Integration Unit, terrain data base, and object detection sensors are processed to produce collision warning audio / visual messages and collision detection and avoidance of terrain and obstacles through generation of guidance commands in a closed-loop system. The vision sensors provide more information for the Integrated System, such as, terrain recognition and ranging of terrain and obstacles, which plays an important role to the improvement of the Integrated Collision Avoidance System.

The present invention relates to a salvage system for a life jacket capable of enabling quick rescue of a victim by quickly finding a victim wearing the life jacket using an artificial satellite and displaying an electronic map provided with the position of the victim and the image of the victim on a screen in real time, when a marine accident or an aircraft accident occurs, and more specifically, to the life jacket, with a marine position tracking terminal attached thereto, which transmits and receives radio signals to and from a GPS satellite and a relay satellite to track the position of the victim, and allowing greater buoyancy to be generated in the head and the chest regions on the surface of the water, when wearing it. A salvage system for a life jacket according to the present invention comprises: a life jacket; a marine position tracking terminal, attached to the life jacket, which transmits a rescue signal and an inherent ID stored in a microcomputer to a plurality of GPS satellites via a rescue signal transmitter; a relay satellite receiving the signal from the marine position tracking terminal and the GPS satellites to calculate a coordinate position of a victim wearing the life jacket and provide it to an integrated geographic information system (GIS), and monitor the image of the victim using the calculated coordinate position; and a central control center receiving in not formation on an electronic map provided with the coordinate position of the victim and the monitored image of the victim from the relay satellite and displaying them on a status screen in real time, thereby enabling follow-up measures for early rescue of the victim.

The invention provides an FTA-based method for testing and analyzing aircraft severe weather environment faults, belonging to the technical field of aircraft testing. Including the following steps: S1, determine the flight accident caused by the bad weather environment as a fault tree top event; S2, carry out statistical analysis on the accident and the accident symptoms related to the weather factor; S3, analyze the set of bad weather factors that cause the aircraft accident and construct the fault tree; S4, construct a failure risk model of the aircraft in severe weather environment; S5, predict the importance of the risk of adverse weather factors affecting flight safety. The invention solves the problem that the prior art lacks the failure analysis method for the aircraft's harsh climate environment, which is not conducive to the design of the aircraft climate test in the climate environment laboratory of the whole aircraft, and has the advantages of simple operation and strong applicability.
