FAA Part 107 Remote Pilot (UAG)Airspace and Operating RequirementsMedium

A remote pilot reviewing a sectional chart sees a dashed magenta line encircling a small airport with no operating control tower. What does this symbol indicate about the airspace?

  1. AIt is Class E airspace that extends down to the surface, requiring the same authorization as Class D
  2. BIt marks the boundary of a Military Operations Area
  3. CIt indicates a Temporary Flight Restriction is currently in effect
  4. DIt is Class G airspace with no altitude restrictions
Show answer & explanation

Correct answer: A. It is Class E airspace that extends down to the surface, requiring the same authorization as Class D

A dashed magenta line around an airport denotes Class E airspace extending to the surface (often at non-towered fields with instrument approach procedures); sUAS operations there require the same controlled-airspace authorization process as Class D airspace.

Why the other options are wrong

  • B. MOAs use different magenta hatched symbology, not a simple dashed line around an airport.
  • C. TFRs are not depicted with dashed magenta lines on standard sectionals.
  • D. Class G is uncontrolled and not marked with magenta dashed lines.

Class E Surface Area

Controlled airspace extending to the surface around certain airports, depicted by a dashed magenta line on sectional charts; requires authorization for sUAS operations like Class D.

  • Dashed magenta line = Class E to surface
  • Common at non-towered airports with instrument approaches
  • Requires LAANC or manual authorization to operate

Memory trick: Dashed magenta = 'Down to the ground' controlled airspace.
