Energy and emission assessments of continuous descent approach

Energy and emission assessments of continuous descent approach Purpose – Continuous descent approach (CDA) is a method, which allows the aircraft flying its individual optimal vertical profile down to runway threshold with engines operating at low‐thrust power. The main objective of this paper is to provide less‐fuel consumption, less noise and less emission with using CDA procedures instead of conventional procedures. Design/methodology/approach – Conventional and CDA procedures were modelled in the Istanbul terminal area (TMA), which has five entry points. The real speed and the real altitude limitations were maintained on these entry points. System for Assessing Aviation's Global Emissions research results were also used to determine the emission savings. Findings – With CDA procedures, more than 40 kg fuel and 2 min time savings per flight are obtained; furthermore, regarding CO 2 and H 2 O, significant emission savings are also noted. Originality/value – Some of the benefits of CDA procedures are reported for Istanbul TMA by using true flight data. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Aircraft Engineering and Aerospace Technology Emerald Publishing

Abstract

Purpose – Continuous descent approach (CDA) is a method, which allows the aircraft flying its individual optimal vertical profile down to runway threshold with engines operating at low‐thrust power. The main objective of this paper is to provide less‐fuel consumption, less noise and less emission with using CDA procedures instead of conventional procedures. Design/methodology/approach – Conventional and CDA procedures were modelled in the Istanbul terminal area (TMA), which has five entry points. The real speed and the real altitude limitations were maintained on these entry points. System for Assessing Aviation's Global Emissions research results were also used to determine the emission savings. Findings – With CDA procedures, more than 40 kg fuel and 2 min time savings per flight are obtained; furthermore, regarding CO 2 and H 2 O, significant emission savings are also noted. Originality/value – Some of the benefits of CDA procedures are reported for Istanbul TMA by using true flight data.
