6.2.5 NAS Surface<br />
Figure 6.9 shows the proposed concept transition path to achieve increased capacity on<br />
the airport surface. <strong>The</strong> chart shows two independent enhancement paths, the one on the<br />
right centered on low visibility operations, the one on the left centered on good VMC.<br />
<strong>The</strong> improvements are described in detail below.<br />
Additional Gates, Taxiways and Aprons<br />
This enhancement will be needed along with any additional runways, or improved runway<br />
utilization, to ensure that the airport surface does not become the constraining factor in<br />
the operation. <strong>The</strong> <strong>Air</strong>port Improvement Program is the cornerstone for this<br />
enhancement.<br />
Reduced Schedule Uncertainty<br />
This enhancement involves reducing variability of operations at major hubs during peaks,<br />
so that arriving aircraft can get to a gate expediently, and thus avoid gridlock on taxiways<br />
and apron areas. This will involve both more predictable aircraft turnaround time, and<br />
better airport flow management, which should result in less schedule padding due to<br />
variance in traffic related delay.<br />
