A reader of IFR Refresher recently inquired about the ATC/Pilot relationship for departures from airports in Class G (uncontrolled) airspace—specifically executing these clearances, and ATC's expectations of how that aircraft will maneuver. Hailing from an en-route center where mountainous terrain dominates and TRACONS are scarce, I frequently encounter situations where aircraft request departure off one of our numerous non-towered airports, most of which are Class E only upon reaching the typical 700 or 1200-foot AGL mark.
