“…ISA dev stands for the ISA temperature deviation, which is the difference from the ISA temperature at a given altitude and the temperature at the "measured" altitude. Using this database, algorithms have been developed to compute the fuel burn, the flight time, and the flight cost 58,59 . These methods are based on the Lagrange interpolation shown in Eq (1):…”

“…For this reason, interpolations are required to compute the exact fuel flow or the exact fuel burn and horizontal traveled distance. This was detailed in [35,36] and a brief explanation is provided next. The trajectory is divided in equidistant segments in order to compute the flight cost.…”

The consumption of fossil fuels in order to power flights leads to undesirable pollution particles to be released to the atmosphere. Fuel also represents an important expense for airlines. For these reasons, it is of interest to reduce fuel burn for a given flight. In this article, the altitudes followed by a commercial aircraft during the cruise phase of a flight, also called vertical reference trajectory, were optimized in terms of fuel burn. The airspace was modelled under the form of a unidirectional graph. Fuel burn was computed using a numerical performance model. The weather forecast was obtained from the model delivered by Environment Canada. The selection of waypoints where to execute the changes in altitudes that provided the most economical flight cost in terms of fuel burn was determined using the particle swarm optimisation (PSO) algorithm. The trajectories provided by the algorithm developed in this paper were compared against simple geodesic trajectories to validate its optimization potential, and against as flown trajectories. Results have showed that up to 6.5% of fuel burn can be saved comparing against simple trajectories, and up to 3.1% was optimized comparing against as flown trajectories.

“…The European Environment Agency (EEA) generates and updates an open source guide called the 'EMEP/EEA Air Pollutant Emission Inventory Guidebook,' which shows fuel consumption and emissions for various aircraft. Other methodologies to compute fuel burn exist, although they differ from the emissions inventory guidebook; such is the case with the Equations of Motions, widely used in the literature (32) , and Performance Database (PDB) methods (33,34) . These alternate methods are time consuming for the objectives of this paper.…”

The aeronautical industry has set for itself important environmental goals, creating the need of improved tools for measuring the polluting emissions generated by fuel burn. This paper describes a new method to estimate the fuel burn and the pollution generated by a landing approach and also for a missed approach procedure. Fuel emission estimations can be used to compare the costs of different routes. The method developed in this paper uses the Emissions Guide Book developed by the European Environment Agency as the needed database for the computations. This method gives estimations of the fuel burn and emissions, including the amounts of CO, NOx, HC, EICO, EINOx and EIHC for a given flight as its output. The flight computation is divided into two sections: one section for the aircraft's travelled distance and a second section for the time an aircraft flies under certain flight modes. Since this method computes the missed approach fuel and emissions contribution, it computes the burn for a given descent approach for a successful landing, as well as for the same descent approach with a missed approach procedure followed by a successful landing. These two landings are verified in a complete flight to study the missed approach contribution for a conventional mid-range flight. The results show that a descent with the missed approach procedure requires 5.7 times more fuel than a normal, successful descent. This extra fuel burn increases the pollution released to the atmosphere and would impact the airlines’ profit margin due to the added fuel costs and longer flight times, as well as any future economic measures imposed on the increased air and noise pollution.
