ATCI: These remote screens serve to reduce collision risk by extending the visual range of controllers. When the tower is equipped with tfte D-Brite III, its operation will be considerably improved. St. Paul Downtown's reliever status will be improved by it being designated as a limited approach control facility, with delegated airspace sufficient to accommodate departures and arrivals independent of Minneapolis-St. Paul arrivals. Other improvements for the St. Paul Downtown tower include an automated surface observing system (ASOS), which provides 24-hour weather information and automatic updating of the ATIS terminal information. With three runways, St. Paul Downtown is well suited for winds from a~ direction during VF1t conditions. It can also operate closed pattern operations on its two shorter runways, while keeping the longer rumvay open for IFR operations. Several heliwpters also operate from St. Paul Downtown. These helicopters generally follow the river to *~++n;m;~~ noise. There is also a seaplane base adjacent to the airport. Seaplane and helicopter operations are all generally compatible with the current level of operations, but improvements such as radar and limited approach control authority will be required with traffic increases. Noise impacts are a constraint to operations at St. Paul Downtown. The azeas surrounding St. Paul Downtown, with the exception of the area to the southeast, aze all populated and sensitive to aircraft noise. A straight-in nonprecision approach is currently being pursued for Rumvay 14. While this approach will improve the airport's ability to accommodate IFR traffic, operational capacity will not be significantly affected. The nonprecision approach on Rumvay 14 will achieve minimums of 500 feet above ground level (AGL). The current circle to land minimums are 876 feet AGL. St. Paul Downtown could also be a viable candidate for a microwave landing system (MIS) installation with an MLS, curved approaches and departure routes could be designed that aze noninterfeting. An MLS would provide IFR procedures to other rttmvays at St. Paul Downtown. There are two instrument approaches to III-31
