“…The cost to carry factors could be estimated from the airline dataset; however, we do not want to include confounding effects of delay, engine use, and other factors that would be present if we were to use the airline data. We therefore simulate gate-to-gate (often termed block) fuel consumption (b) with Piano-5, a state-of-the-practice aircraft performance analysis software by Lissys (Pham et al 2010, Skowron et al 2013. Piano is frequently used in both research and practice for aviation fuel modeling to predict fuel consumed as a function of aircraft dynamics and flight mission characteristics (Svensson et al 2004, Owen et al 2010, Krammer et al 2013, Dray 2014.…”

Airlines and Air Navigation Service Providers are united in their goal to reduce fuel consumption. While changes to flight operations and technology investments are the focus of a number of studies, our study is among the first to investigate an untapped source of aviation fuel consumption: excess contingency fuel loading. Given the downside risk of fuel exhaustion of diverting to an alternate airport, airline dispatchers may load excess fuel onto an aircraft. Such conservatism comes at a cost of consuming excess fuel, as fuel consumed is a function of, among other factors, aircraft weight. The aim of this paper is to quantify, on a per-flight basis, the fuel burned due to carrying fuel beyond what is needed for foreseeable contingencies, and thereby motivate research, federal guidance, and investments that allow airline dispatchers to reduce fuel uplift while maintaining near zero risks of fuel exhaustion. We merge large publicly available aviation and weather databases with a detailed dataset from a major US airline. Upon estimating factors that capture the quantity fuel consumed due to carrying a pound of weight for a range of aircraft types, we calculate the cost and greenhouse gas emissions from carrying unused fuel on arrival and additional contingency fuel above a conservative buffer for foreseeable contingencies. We establish that the major US carrier does indeed load fuel conservatively. We find that 4.48% of the fuel consumed by an average flight is due to carrying unused fuel and 1.04% of the fuel consumed by an average flight is due to carrying additional contingency fuel above a reasonable buffer. We find that simple changes in flight dispatching that maintain a statistically minimal risk of fuel exhaustion could result in yearly savings of 338 million lbs of CO 2 , the equivalent to the fuel consumed from 4760 flights on midsized commercial aircraft. Moreover, policy changes regarding maximum fuel loads or investments that reduce uncertainty or increase the ability to plan flights under uncertainty could yield far greater benefits.

“…However, when it comes to asserting an average FF at a specific altitude or aircraft mass, long ULFs might lead to inaccurate results since the variation of aircraft mass from the start and end of the ULF is too great to link an average aircraft mass with an average FF. In the relevant literature, there are studies in which reduction of aircraft weight, along with fuel consumption, has been taken into consideration [4][5][6], while in others these effects have been neglected [3]. However, in this study, this is considered and therefore, in certain analyses, a different approach is taken.…”

Fuel flow rate of an aircraft varies significantly during a typical flight, mainly due to required engine thrust, speed, weather conditions, aircraft configuration and aircraft mass. Of these, the effect of aircraft mass, being the non-payload portion, on fuel flow is investigated in this study. The investigation is carried out for twin-engined wide-bodied aircraft, during its intercontinental flights. Based on actual flight data records, two approaches are developed, in which the fuel flow rate is estimated based on three independent variables; altitude, aircraft mass and flight speed. The regression models are found to be highly significant and average fuel consumption is found to be 2-3% of the non-payload mass per flight hour. It should be noted that this percentage is affected by flight altitude and aircraft initial mass, of which the latter has a greater effect. In addition, it is worth noting that when the aircraft initial mass increases, the fuel consumption percentage also tends to increase.

“…However, these calculations were performed for entire flights and were not applied for specific landing approach procedures. These methods used information from the tables provided by the Emission Inventory Guidebook (EIG) (29)(30)(31) . Other different tools have been developed to estimate noise and pollution released to the atmosphere.…”

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.
