SLOWING AIRCRAFT DEPARTURE SPEED CUTS NOISE SIGNIFICANTLY, MIT STUDY FINDS

摘要

Slowing aircraft departure speed by about 30 knots (35 mph) – to the point atrnwhich airframe and engine noise are equal – could significantly reduce noise on thernground, according to an MIT aeronautics professor who is leading a landmarkrnstudy at Boston Logan International Airport seeking ways to reduce the noise impactrnof concentrated NextGen flight tracks.
