A remote pilot plans to fly at 300 feet AGL for an agricultural survey 3 miles from an uncontrolled airport (no operating tower). The sectional chart shows a dashed magenta circle around the airport. What authorization, if any, is required?
ANo authorization: the airport has no control tower, so the surrounding airspace is Class G.
BLAANC or DroneZone authorization is required: the dashed magenta circle indicates Class E to the surface, which requires authorization under 14 CFR § 107.41.✓ Correct answer
CNo authorization: Part 107 only requires authorization in Class B, C, and D airspace.
Why →14 CFR § 107.41 requires authorization for sUAS operations in Class B, C, D, and Class E airspace designated for an airport, including Class E to the surface. The dashed magenta circle on a sectional chart indicates Class E to the surface, which protects IFR approaches even at airports without operating control towers. Many pilots incorrectly assume no tower means no authorization required.
The trap →No control tower does not mean Class G airspace. Many smaller airports have Class E surface areas protecting IFR instrument approaches. The dashed magenta circle specifically indicates Class E to the surface. Distinct from solid magenta shading (Class E starting at 700 feet AGL).
