Evaluation of Flight Efficiency for Stockholm Arlanda Airport Arrivals

Abstract

Analysis of punctuality of airport arrivals, as well as identification of causes of the delays within transition airspace, is an important step in evaluating performance of the Terminal Maneuvering Area (TMA) Air Navigation Services: without knowing the current performance levels, it is difficult to identify which areas could be improved. Deviations from the flight plans is one of the major reasons for arrival delays. In this work, we evaluate punctuality of Stockholm Arlanda airport arrivals and quantify the impact of the deviations from the flight plans on the fuel burn. Another reason of fuel waste is non-optimal vertical profiles during the descent phase. We evaluate additional fuel burn due to vertical flight inefficiency within Stockholm TMA.
