Ecological and Operational Aspects of Continuous Descent Approach – Croatian Case

Abstract

 Abstract—The impact of air traffic on total air pollution is a measurable value. This paper will present, on the Croatian example, the benefits of Continuous Descent Approach procedure in terms of reducing atmospheric emissions by reducing fuel consumption. Air traffic is accountable for 2% of global CO 2 emissions. Although that is a small percentage, due to the higher altitudes at which the emissions are released, total impact on the global warming is considered to be between 3.5% and 5%. Urgent action is required to reduce fuel burn and to make emissions savings, in order to reduce operating costs of airlines (financial aspect), and to reduce release of greenhouse gas emissions (environmental aspect). Also, it is imperative to reduce aviation noise impact on public in general. Introducing Continuous Descent Approach, as a flight operating technique in commercial aircraft operations will be a mean to achieve ecological and financial objectives. The presented results and the methodology can be used in process of operational procedures design for approach phase of the flight.
