Why are you showing in your maps that aircraft will be lower than they are today?
Aircraft fly over any given area at a range of altitudes. We recognize that the lowest aircraft, whilst less frequent than those flying at an average height, are likely to have a disproportionate impact, therefore in our maps we have shown the worst case heights for aircraft.
In general the proposal will mean aircraft climb higher quicker on departure and stay higher longer on arrival, however the maps cover the range of potential aircraft heights from worst case upwards.
