The instrument runway, Rtmway 32, is served by an instrument landing system (ILS) with straight-in minimums of a 400-foot ceiling and visibility of one mile for Category C aircraft and up. There is also a nondirectional beacon (NDB) approach procedure for Runway 30 with much higher minimums of a 900-foot ceiling and varying visibilities of one to two and threeyuarter miles, depending on the aircraft category. Unfortunately, if there are strong winds from the southeast, south, or west, aircraft have to circle to land on one of the other runways more closely aligned with the wind. In order to successfully execute a circling. approach, the minimums must be fauly high, as stated above. When ceilings .are below circling minimuttu, the aircraft must divert to an alternate airport with a rumvay aligned close to or into the wind. ILS approaches to Runway 32 conflict with departures on Runway i1L at Minneapolis-St. Paul International. (This conflict does not exist for 11R.) Inbound traffic at St. Paul Downtown must hold for 30 minutes if Minmeapolis-St. Paul departures are occurring on Runway 11L If traffic is heavy at Minneapolis-St. Paul, departures are held while St. Paul Downtown accommodates inbound traffic. Operations at St. Paul Downtown are kept below or underneath Minneapolis- St. Paul International operations. Occasionally, during very hot weather, St. Paul Downtown departures to the south and southeast must be staggered with Minneapolis-St. Paul International departures. This is particularly true for heavy, slow-climbing B747s enroute non-stop to Europe or destinations in the east and south. Arrivals blend in with the regular flows to Minneapolis-St. Paul International, but they are kept. at lower altitudes. St. Paul Downtown currently has a tower, but it is inadequate due to its age. The construction of a new tower, however, is currently being considered. The tower is scheduled to be equipped with a Digital Bright Radar Indicator Tower Equipment (D-Brits III) radar monitor, but the date for this installation is not firm. A D-Brits monitor is a remote radar screen that provides simultaneous displays is satellite III-30
