Additional information for ASN 2015-AGL-9153-OE AERONAUTICAL STUDY NO. 2015-AGL-9153-OE MSL-Mean Sea Level IFR - Instrument Flight Rules RWY --runway AGL-Above Ground Level VFR - Visual Flight Rules nm - nautical mile MDA- Minimum Descent Altitude Part 77 -Title 14 Code of Federal Regulations (CFR) Part 77, Objects Affecting Navigable Airspace This temporary crane at 227 feet AGL/1088 feet AMSL has been identified as an obstruction under the standards of Title 14, Code of Federal Regulations (CFR) Part 77, as applied to Dane County Regional-Truax Field(MSN) in Madison,WI. The temporary crane would be located approximately 9,775 feet(1.60 nm) south of the existing RWY 36 threshold at the MSN Airport. This crane will be used to construct a new building. MSN elevation is 886 feet MSL. Scheduled time of operation: This crane will be on site approximately 14 months. This temporary crane would exceed these MSN Part 77 protected surfaces: Section 77.17(a)(2) -A height that is 200 feet AGL, or above the established airport elevation, whichever is higher, within 3 nautical miles of the established reference point of an airport with its longest runway more than 3,200 feet in actual length. The temporary crane would exceed 200 feet above the airport elevation within 3 nautical miles of MSN by 2 feet. Section 77.19(a)--A horizontal plane 150 feet above established airport elevation, the perimeter of which is constructed by swinging arcs of a specified radii from the center of each end of the primary surface of each runway of each airport and connecting the adjacent arcs by lines tangent to those arcs. The temporary crane would exceed the MSN horizontal surface by 52 feet. The temporary crane has the following effects on IFR operations at MSN: Section 77.17(a)(3): A height that increases a minimum instrument flight altitude within a terminal area (TERPS criteria) the structure would have the following IFR impacts: ILS or LOC/DME RWY 36, increase S-LOC 36 MDA by 160 feet from 1240 feet MSL to 1400 feet MSL. VOR RWY 36, "ISMUZ FIX MINIMUMS increase S-36 MDA by 80 feet from 1320 feet MSL to 1400 feet MSL. HI-TACAN RWY 36, increase S-36 MDA by 80 feet from 1320 feet MSL to 1400 feet MSL. RNAV (GPS) RWY 36, increase LNAV MDA by 100 feet from 1300 feet MSL to 1400 feet MSL METHODS OF NOTIFICATION - It is required that the FAA by notified 3 business days prior to the temporary structure being erected and again when the structure is removed from the site. Notification should be made to this office through your registered e-filing account. Notification is necessary so that aeronautical procedures can be temporarily modified to accommodate the structure. Page 3 of 6
