Noise abatement is a concern for ATM today – with different level of emphasis depending on the local situation – but only generic procedures are employed that aim at increasing the height of the flight path (raising intermediate altitudes, increasing glide path angle and initial climb angles) and its horizontal distance from noise-sensitive areas. At busy times, there is normally not enough leeway to allow Continuous Descent Operations (CDO) that minimise fuel consumption and engine noise by flying from Top of Descent (ToD) through intermediate approach at near idle power.
