Aircraft Flight Path Correction During the Flight Execution Phase Using the Operative Information on Weather Hazards

Modern aviation system operation is based on advanced technologies that allow to obtaining of crucial flight information in real-time. Systems of air navigation support share different data with all air space users to ensure the safety of air transportation. It plays an important role in operative flight trajectory correction when hazardous areas are detected along the pre-planned flight trajectory. However, this data may be unavailable at the stage of flight planning. In this paper, we consider weather-related hazards that influence the flight during the en-route flight phase. Also, we consider potential of modern information systems to obtain and share operative meteorological information as well as to use this information for in-flight trajectory correction. The Bellman algorithm was chosen to calculate the shortest part taking into account the operatively detected hazards. The simulation of trajectory correction taking into account different weather situation in the same area is done and results of simulation are discussed.
