Part 107 test practice question: Airspace Classification and Operating Requirements

Airspace Classification and Operating RequirementsDifficulty 2/5

On a sectional chart, a dashed blue line around an airport indicates which airspace, and what must a remote PIC obtain to fly inside it?

  1. AClass C; nothing, if below 400 ft
  2. BClass D; ATC authorization (e.g., LAANC)
  3. CClass E at 700 ft; nothing
  4. DClass G; nothing
Show answer and rationale

Correct: B. A dashed blue line is Class D airspace, which extends to the surface. §107.41 requires ATC authorization for operations in Class B, C, D and surface-area Class E, typically obtained through LAANC.

  • A — Class C is a solid magenta line, and authorization is required there too.
  • C — Class E at 700 ft AGL is the shaded magenta vignette.
  • D — Class G is uncontrolled and not depicted by a dashed blue line.
