A noise reduction of between three and five decibels and fuel savings of up to 500 kilograms per landing can be achieved, provided that pilots have access to an environment-friendly approach path during landing. In approaches of this kind, known as CDAs (Continuous Descent Approaches), the aircraft descends continuously - much like a glider – from its cruising altitude to final approach without interrupting its descent profile or applying more thrust. Depending on their equipment configuration, aircraft fly different routes and profiles on landing approaches.
