In Option 1, the new runway would be closer to the existing runway than the minimum separation of 760m needed to provide independent operations;
Therefore runway operations in Option 1 would be dependent. This would provide more capacity than a single runway, but it does not provide as much capacity as a pair of independent runways;
For our planning, we have used a maximum combined hourly movement rate of 70 aircraft movements per hour compared to the 55 that is possible on the single runway;
One runway would be used for arriving flights and the other used for departing flights. This is known as segregated mode;
The runways in Option 1 are too close together to provide an additional terminal and stands in the space between them, so all such capacity would need to be accommodated in the existing North and South Terminals and northern apron.
