The current Flight Management System (FMS), CMA-9000, from CMC Electronics - Esterline, only optimizes the vertical flight profile in terms of aircraft speeds. This article defines a methodology that optimizes the vertical flight profile in terms of speeds and altitudes, obtaining a trajectory that reduces the global flight cost. © 2012 IEEE. Source

This paper presents an algorithm for determining the optimal cruise altitude for an aircraft flying at a constant speed and level flight on a given flight route segment. The optimization criteria correspond to the minimization of the total costs associated with flying a cruise segment, including the costs related to fuel consumption (when possible). The algorithm makes use of a new method for computing fuel burn for level-flight cruise segments, based on an aircraft's performance data. The new fuel burn method was developed for aircraft models that use the center of gravity position as well as for models that do not consider the center of gravity position. This algorithm was developed for normal flight conditions and does not consider the costs associated with the initial and final changes of altitude required to reaching the optimal altitude, nor those needed at the end of a segment to return to the initial cruise altitude. Algorithm performances were evaluated for two aircraft models: one for models that use an aircraft's center of gravity position - a more complex and computing intensive method, and one for those that do not use the center of gravity position. The validation data were generated based on the information produced on a CMC Electronics - Esterline FMS platform that used identical aircraft models and performance data for identical flight conditions. © 2012 by Bogdan D.

In order to implement a trajectories optimization algorithm into the Flight Management System CMA-9000 from CMC Electronics - Esterline, an algorithm with a short calculation time has to be designed. The performance databases are supplied by CMC Electronics - Esterline for three aircraft: the Airbus A310, the Lockheed L-1011 and the Sukhoi Superjet 100. To create flight trajectories, performance characteristics have to be interpolated in these databases. An interpolation procedure is defined in this algorithm to calculate fuel burn, distance traveled and flight time, with the lowest algorithm execution time possible. Source

The current Flight Management System, CMA-9000, from CMC Electronics - Esterline, does not include a cruise optimization. In the presence of winds, the aircraft fuel consumption is highly affected. If the aircraft experiments head winds, the consumption will increase, and the consumption will decrease in the case of tail winds. The cruise phase is analyzed using genetic algorithms to obtain the maximal optimization possible in the least calculation time. In this article, an algorithm will be defined, that will be capable of selecting an alternative trajectory to take advantage of tail winds in the flight path, and to avoid as much as possible the presence of head winds, to reduce fuel burn.

To obtain the most fuel-efficient trajectory for an aircraft and reduce the flight cost, all possible trajectories should be calculated, including all possible IAS/Mach combinations. The analyze of all possible trajectories would result in a large calculation time, and for a device such as the Flight Management System CMA-9000, from CMC Electronics - Esterline, the calculation time is limited. In order to reduce the search space for solutions and reduce calculation time, genetic algorithms are considered. Different on-flight restrictions imposed by the Air Traffic Control should be considered, such as flying altitude and speed. Source
