Improved energy management during arrival for lower noise emissions

Abstract

Analysis of operational flight data has shown that energy management during approach is a challenging task for pilots. This is detrimental for both fuel consumption and noise emission. The difficulty is increased when shortcuts result in an over-energy scenario. To alleviate the situation, a novel functionality was developed which improves aircraft energy management during descent and approach. It includes cues shown in the Primary Flight Display and the Navigation Display of an exemplary single-aisle aircraft. Noise benefits of the functionality were evaluated during piloted real-time simulation trials. Using the functionality, noise emissions during descent and approach can be decreased in the area within 10 NM from the threshold.
