How does weather affect aircraft noise?
In IMC (Instrument Meteorological Conditions) the visibility and cloud cover are low enough that an airplane must fly to an airport via on-board instruments along a route identified on a published instrument approach procedure. The aircraft will fly at the MDA (Minimum Decent Altitude) to a point at which it has visual contact with the runway and safely lands or must fly the missed approach procedure because visual contact with the runway was not made and a safe landing is not possible. In IMC conditions the aircraft noise is amplified due to the cloud cover containing the noise near the ground. In aviation, safety is always of utmost importance first and in IMC conditions, an increased level of noise should be anticipated.
