Airport Master Plan October 1985

6.4 Approach Slopes/Operation Limitations Runway 34 is a designated non -precision instrument runway with a VOR approach. Minimums for Category A and B aircraft are: Straight -in 1 mile visibility and 1480' (605' MDA) Circle -to -land 1 mile visibility and 1540' (665' MDA) Runways 9, 27 and 16 currently have visual approach surfaces. MN/DOT and the Metropolitan Council recommend non -precision instrument approaches (NPI) for this classification of airport. The state criteria for NPI approaches is a 40:1 design slope rather than FAA's 34:1 design slope. The clear zones associated with these approaches thus are 500 feet x 2000 feet x 1100 feet. It is recommended that each runway end be planned for a non -precision approach. There is no height limitation zoning plan in effect which protects FAR Part 77 imaginary surfaces. The City has restricted the height of structures throughout the Community to 35 feet maximum height. It is recommended that a height limitation zoning plan and land use safety plan be adopted to protect the planned approach surfaces. 6.5 Approach Navaids/Lighting It is reco mended that the primary runway be lighted with a Medium Int nsity Runway Lighting (MIRL) system with exit taxiway li hts. The taxiway straight aways should be equipped w th retroreflectors. Runway end identifier lights (REILS) and a visual approach slope indicator (vasi) should be installed to serve each runway end. A lighted wind cone and rotatirg beacon are also recommended. Obstruction lights should be installed on obstructions which cannot be removed or alleviated. 6.6 Land Sufficient land should be acquired to provide for an ulti- mate 3300 feet runway and associated approach zones (2400') from each r anway end to accommodate MN/DOT A zones in which development is prohibited. Adequate land area to provide for building area development must also be acquired. It is recommended that land be acquired in fee rather than ease- ments whenever possible. 6-4
