AIRPORT. The Elbow Lake Municipal Airport located in Section 17, Township 129 North, Range 42 West, Grant County, Minnesota.
AIRPORT ELEVATION. The established elevation of the highest point on the usable landing area which is established to be 1,204 feet above mean sea level.
AIRPORT HAZARD. Any structure or tree or use of land which obstructs the airspace required for, or is otherwise hazardous to, the flight of aircraft in landing or taking off at the airport; and any use of land which is hazardous to persons or property because of its proximity to the airport.
APPROACH/DEPARTURE PATH. The flight track helicopters follow when landing at or departing from a heliport. The approach/departure paths may be straight or curved.
COMMISSIONER. The Commissioner of the Minnesota Department of Transportation.
CONFORMING USE. Any structure, tree or object of natural growth or use of land that complies with all the applicable provisions of this chapter or any amendments to this chapter.
DWELLING. Any building or portion thereof designed or used as a residence or sleeping place of one or more persons.
FINAL APPROACH AND TAKEOFF AREA (FATO). The area surrounding the touchdown and liftoff area (TLOF) over which the pilot completes the final phase of the approach to a hover or a landing and from which the pilot initiates takeoff. The FATO elevation is the lowest elevation of the edge of the TLOF.
HEIGHT. For the purpose of determining the height limits in all zones set forth in this chapter and shown on the zoning maps, the datum shall be mean sea level elevation unless otherwise specified.
HELIPORT. The Prairie Ridge Hospital and Health Services Heliport located in Elbow Lake, Minnesota.
HELIPORT ELEVATION. The established elevation of the lowest point on the usable landing area which is established to be 1,229 feet above mean sea level.
HELIPORT HAZARD. Any structure, tree, or use of land which obstructs the airspace required for, or is otherwise hazardous to, the flight of aircraft in landing or taking off at the heliport; and any use of land which is hazardous to persons or property because of its proximity to the heliport.
LANDING AREA. The area of the airport used for the landing, taking off or taxiing of aircraft.
LANDING POSITION. An area, normally located in the center of an elongated TLOF, on which the helicopter lands.
LOW DENSITY RESIDENTIAL LOT. A single lot located in an area which is zoned for single-family or two-family residences and in which the predominant land use is such type of residences.
LOW DENSITY RESIDENTIAL STRUCTURE. A single-family or two-family home.
NONCONFORMING USE. Any pre-existing structure, tree, natural growth or use of land which is inconsistent with the provisions of this chapter or an amendment hereto.
NON-PRECISION INSTRUMENT RUNWAY. A runway with a straight-in instrument approach procedure using either ground-based or satellite-based air navigation facilities. A runway having an existing or planned straight-in instrument approach procedure utilizing air navigation facilities with only horizontal guidance, and for which no precision approach facilities are planned or indicated on an approved planning document.
OBSTRUCTION TO AIR NAVIGATION. Any fixed or mobile object, including a parked helicopter, of greater height than any of the heights or surfaces presented in this chapter.
OTHER-THAN-UTILITY RUNWAY. A runway that is constructed for and intended to be used by jet aircraft or aircraft of more than 12,500 pounds maximum gross weight; or is 4,900 feet or more in length.
PERSON. An individual, firm, partnership, corporation, company, association, joint stock association or body politic and includes a trustee, receiver, assignee, administrator, executor, guardian or other representative.
PLANNED. Proposed future airport developments that are so indicated on a planning document having the approval of the Federal Aviation Administration, Minnesota Department of Transportation Office of Aeronautics, and the City of Elbow Lake.
PRIMARY SURFACE. Heliport primary surface that coincides in size and shape with the designated final approach and takeoff area (FATO) as defined in the latest edition of the FAA Heliport Design Advisory Circular No. 150/5390-2C.
PRECISION INSTRUMENT RUNWAY. A runway with an instrument approach procedure utilizing an Instrument Landing System (ILS), a Microwave Landing System (MLS), a Precision Approach Radar (PAR), a Transponder Landing System (TLS), or a satellite-based system capable of operating to the same level of precision guidance provided by the other included systems. Also, a runway for which a precision instrument approach system is planned and is so indicated on an approved planning document.
RUNWAY. Any existing or planned paved surface or turf covered area of the airport which is specifically designated and used for the landing and/or taking off of aircraft.
SAFETY AREA. A defined area on a heliport surrounding the FATO intended to reduce the risk of damage to helicopters accidentally diverging from the FATO and to protect people from injury and property from damage due to the operation of the helicopter.
SLOPE. An incline from the horizontal expressed in an arithmetic ratio of horizontal magnitude to vertical magnitude.
Slope = 3:1 = 3 feet horizontal to 1 foot vertical.
STRUCTURE. An object constructed or installed by humans, including, but without limitation, buildings, towers, smokestacks, earth formations and overhead transmission lines.
TOUCHDOWN AND LIFTOFF AREA (TLOF). A load-bearing, generally paved area, normally centered in the FATO, on which the helicopter lands and/or takes off.
TRAVERSE WAYS. For the purpose of determining height limits as set forth in this chapter, shall be increased in height by 17 feet of interstate highways; 15 feet for all other public roadways; ten feet or the height of the highest mobile object that would normally traverse the road, whichever is greater, for private roads; 23 feet for railroads; and for waterways and all other traverse ways not previously mentioned, an amount equal to the height of the highest mobile object that would normally traverse it.
TREE. Any object of natural growth.
UTILITY RUNWAY. A runway that is constructed for and intended to be used by propeller-driven aircraft of 12,500 pounds maximum gross weight and less and is less than 4,900 feet in length.
VISUAL RUNWAY. A runway intended solely for the operation of aircraft using visual approach procedures, with no straight-in instrument approach procedure and no instrument designation indicated on an approved planning document.
WATER SURFACES. The same meaning as land for the establishment of protected zones.
