Teniendo en cuenta que de los diversos tipos de DME existentes son: DME/N Modo Y, DME/N Modo X y DME/P.

Los disenos seran efectuados de manera que solo puedan ser utilizados por aeronaves equipadas con sistema RNAV, por lo tanto se realizara la suposicion de que todas las aeronaves poseen dicho equipo. Por lo tanto, el excluira los circuitos de espera y la aproximacion inicial e intermedia, que en la navegacion P-RNAV son sustituidas por las transiciones. Se realizara una completa codificacion de los datos y las cartas segun la normativa establecida para tal efecto.

Currently, aircraft operators are requesting more flexibility to fly according to their prefer- ences, in order to achieve their business objectives. Due to this reason, much research effort is being invested in developing different techniques which evaluate aircraft optimal trajectory and traffic synchronisation. Also, the inefficient use of the airspace using barometric altitude overall in the landing and takeoff phases or in Continuous Descent Approach (CDA) trajectories where currently it is necessary introduce the necessary reference setting (QNH or QFE). To solve this problem and to permit a better airspace management born the interest of this research.

However, there are many systems that operate in the L-Band (960-1215MHz) that could produce interference between systems. At airports, some interference has been detected between transmissions of MLT systems (1030MHz and 1090MHz) and Distance Measuring Equipment (DME) (960- 1215MHz).

Trajectory prediction should incorporate variables such as air pressure ( p), wind velocity ( w) and temperature ( T), as well as clouds/visibility, gusts/microbursts and the concentration of particles or other elements that can affect aircraft travel through the atmosphere. Today’s commercial aircraft normally carry equipment that contains automatic dependent surveillance-broadcast system which broadcast usable information that can be used for different purposes. This article explores the characteristics of the information supplied by automatic dependent surveillance-broadcast, not for surveillance purposes, but for the provision of valuable atmospheric information that could support four-dimensional trajectory management. It also provides information on the strengths and weaknesses of automatic dependent surveil...

In an effort to contribute for sustainable aviation, this work aims at presenting the efficiency enhancements at terminal airspace operation through the multi-objective trajectory optimisation of flight departures. This study put in place consolidated multi-objective models in terms of noise and fuel consumption for the calculations of optimised aircraft trajectories based on Continuous Climb Operations (CCOs) principles. The conclusions will bring the reader more relevant insights on determining the effects when ATC facilitates the performance of this type of operation.
