Abstract [en]

Asteeper approach path is one potential way to reducetheperceived aircraft noise level on the ground around airports. However,pilots'changed operating behavior on a steeper glide slope may have an impact, or even acounterbalancing effecton the desired noise reductionoutcome. The overallaim of thisresearchis to estimate pilot impact on the noise abatementin steeper approaches.Actual recorded winds during standard 3.0degree glide slope angle approaches will be used to developan equivalent zerowind glide path angle. Correlations of glide slope angle and pilot operational behaviorwill be analyzed. In this paper,the logic behind thedevelopment ofan equivalent zero windcalculation methodis presented. A user-centered approach was applied which included a pilot workshop, and interviews with airline pilots.Based on the results it was decided to use the average wind from glide slope intercept to landing gear extension for the analysis of the pilots' behavior. Theequivalent zerowind calculation methodselected willsubsequently be applied to analyzepilot impact on noise abatement at various glide path angles.This will increase the knowledge about how to minimize the actual noise footprint around airports considering varying glide slope angles and meteorological conditions.
