FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsMedium
A drone pilot plans an aerial survey within the two-tiered circular airspace surrounding a medium-sized commercial airport with radar approach control services. What class of airspace is this, and what does the pilot need before flying?
- AClass B airspace, which does not require any authorization for UAS below 400 feet
- BClass E airspace, requiring only weather minimums to be observed
- CClass C airspace, requiring ATC authorization before operating
- DClass G airspace, requiring no coordination with any facility
Show answer & explanationAnswer & explanation
Correct answer: C. Class C airspace, requiring ATC authorization before operating
Class C airspace is typically depicted on sectionals as two overlapping circles around airports with an operating control tower and radar service; Part 107 requires ATC authorization to operate in Class C airspace.
Why the other options are wrong
- A. Class B has a different, more complex 'upside-down wedding cake' shape and still requires authorization.
- B. Class E does not have the described two-tier circular shape and can still require authorization if surface-based.
- D. Class G is uncontrolled and has no such radar-service structure.
Class C Airspace
Controlled airspace around medium-sized airports with an operating control tower and radar approach control, depicted as two concentric circles.
- Typically has a 5 NM inner core surface to 4,000 ft AGL and a 10 NM shelf
- Requires ATC authorization under Part 107.41
- Depicted with solid magenta circles on sectional charts
- Provides radar services to arriving/departing traffic
Memory trick: Class C = 'Circles, Circles' - two rings around the airport
