Embodiment Construction

[0103] figure 1 and figure 2 A system for computing an aircraft trajectory 100 from a description of an aircraft intent 114 , which in turn is derived from a description of a flight intent 101 , is shown in .

[0104] figure 1 The basic structure of how flight intents may be used to derive aircraft intents and how aircraft intent descriptions 114 may be used to derive descriptions of aircraft trajectories 122 is shown. In essence, the flight intent description 101 is provided as input to the intent generation infrastructure 103 . The intent generation infrastructure 103 determines the aircraft intent using the instructions provided by the flight intent 101 and other inputs to ensure that a set of instructions is set to an aircraft intent description 114 that will allow the unambiguous trajectory 122 to be calculated. This process may include the intermediate steps of enriching the flight intent 101 and completing the enriched flight intent to provide a parametric aircraft ...

Abstract

The present invention provides a computer-implemented method of generating an aircraft intent description expressed in a formal language that provides an unambiguous four-dimensional description of an aircraft's intended motion and configuration during a period of flight. A flight intent description is parsed to provide instances of flight intent that span a flight segment, the flight segments together spanning the period of flight. The parsed flight intent is enriched with objectives and constraints according to user preferences, operational context and aircraft performance. The resulting enriched flight intent is converted into a parametric aircraft intent description by ensuring that each flight segment closes all associated degrees of freedom of motion and of configuration of the aircraft. At least some instances of aircraft intent contain a parameter range, and the method further comprises optimising the parametric aircraft intent by determining an optimal value for the parameter of each parameter range.

Description

technical field [0001] The present invention relates to providing a method of forming an aircraft intent description expressed using a formal language. Such descriptions allow unambiguous prediction of the path of the aircraft. Background technique [0002] The ability to predict aircraft trajectories is useful for several reasons. By trajectory, a four-dimensional description of the aircraft's path means that eg the three-dimensional position of the aircraft can be specified at each of a series of points in time. This description may be the evolution of the state of the aircraft over time, where the state may include the position of the center of mass of the aircraft and other aspects of its motion, such as velocity, attitude, and weight. [0003] Air traffic management (ATM) would benefit from an improved ability to predict the four-dimensional trajectories of aircraft. Air traffic management is responsible for the safe separation of aircraft, a particularly difficult t...
