Airspace Classification and Operating RequirementsDifficulty 3/5
A planned flight at 300 ft AGL is inside the shaded magenta vignette but outside any dashed magenta or blue lines. Which is correct?
- AOnly a NOTAM is required
- BAuthorization is required because the area is Class E
- CThe flight is in Class G below the 700-ft Class E floor; no authorization is needed
- DThe flight is prohibited
Show answer and rationale
Correct: C. The magenta vignette marks Class E beginning at 700 ft AGL. Below that floor the airspace is Class G, so a 300-ft flight needs no ATC authorization (all other Part 107 rules still apply).
- B — Class E here begins at 700 ft AGL, above the flight.
- D — Nothing prohibits Class G operations.
- A — NOTAMs are checked, not filed, for routine Part 107 flights.
