Embodiment Construction

[0083] The tool according to the invention is improved within the SESAR engineering framework established by the European Union [5].

[0084] The method according to the invention may also be referred to below as "Vertical Trajectory Prediction Algorithm" (VTPA). The method was invented with the aim of predicting the altitude distribution of aircraft trajectories during typical missions, within the framework of the enhanced flight data processing system (e-EDP), that is, the integrated tool that supports the behavior of the main Air Traffic Management (ATM) European Control Center. The altimetry profiles mentioned above can be combined with survey track profiles to allow overall track prediction.

[0085] The main purpose of the algorithm implementation is to generate realistic vertical trajectory profiles for each mode of operation commanded by the air traffic controller. All executed modes of operation are reported in the following sections.

[0086] The vertical trajector...

Abstract

The invention concerns a method and system for the prediction of aircrafts vertical trajectory, in particular for Air Traffic Management, comprising the following flight calculation modules: Take-off; Climb; Cruise; Descent; and Landing, corresponding to the relevant flight phases, wherein: the calculation of the predicted aircraft trajectory is effected by using a set of TEM equations comprising, as output variables, the vertical rate of climb or descent, the true air speed, the energy share factor, the thrust and the drag, the mass of the aircraft modeled as point-mass, and comprising, as inpu variables, the Mach number depending on true air speed and temperature and altitude, the gravity acceleration, and the fuel flow, and the flight path angle; the calculation of the predicted aircraft trajectory for Cruise phase, wherein only the mass is varying, is performed by using the following analytical solution to said set of TEM equations.

Description

technical field [0001] The present invention relates to a fast vertical trajectory prediction method for air traffic management (ATM), and related ATM systems. [0002] In more detail, the invention relates to a method capable of calculating the vertical trajectory of an aircraft by integrating numerical and analytical solutions of several flight phases in a fast and computationally efficient manner using suitable methods. The invention further relates to an ATM system implementing the method of the invention. Background technique [0003] Currently the ATM system supports flight. However, the associated international traffic is growing rapidly [4, 5], requiring a multi-flight ATM system that is larger than any current operating system. [0004] Therefore, the level of automation of the ATM process must be increased to fulfill this demand. The number of vehicles planned to fly in the next generation aviation area will require an unrealistic number of human controllers [6]...
