Uncontrolled IFR

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.

Key Takeaways:

• While IFR flight in uncontrolled (Class G) airspace without an ATC clearance is technically permissible under some regulations, it is practically unfeasible for an entire flight in the U.S. due to limited high-altitude Class G and other applicable IFR rules like minimum altitudes and instrument approach requirements.
• NTSB cases have ruled that conducting IFR operations in uncontrolled airspace without an ATC clearance, even for segments like departures, constitutes "careless or reckless operation" (91.13) due to inherent dangers like lack of traffic separation and unpredictable conditions.
• This "pure" uncontrolled IFR is distinct from common scenarios where IFR flights, initiated with an ATC clearance, briefly transition into Class G airspace during departures (below Class E floors) or instrument approaches.
