Uncontrolled IFR

We’re all familiar with the clearance that begins, “Upon entering controlled airspace, fly heading…” But, what if you’re not going to enter controlled airspace?

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.
