Operations take place daily in uncontrolled airspace. Paynesville, MN (KPEX) is a typical non-towered airport with the familiar vignette depicting Class E beginning at 700 feet AGL. Departing Paynesville, any time we spend in the clouds below the Class E floor is IFR in uncontrolled airspace. Of course, as you should recall, lacking that magenta vignette, the 700-foot limit becomes 1200 feet. Instrument approaches begin with an ATC clearance in controlled airspace, but often take us into uncontrolled Class G airspace. At Paynesville, the RNAV (GPS) RWY 11 approach LPV mins take us to 200 feet AGL, 500 feet into the surface Class G airspace.
