Airspace & ChartsQuestion 46 of 100
A sectional shows a large airport surrounded by several solid blue rings of increasing radius, forming an upside-down wedding cake. The innermost ring is labeled 70 above SFC. A remote pilot wants to fly at 150 ft AGL from a rooftop inside that innermost ring. What applies?
a.The site is in Class B surface airspace, so ATC authorization is required before flight
b.No authorization is needed because the operation stays below 400 ft AGL
c.Authorization is needed only if the aircraft will climb above 1,200 ft AGL
d.Part 107 operations are permanently prohibited anywhere inside Class B airspace
Explanation
An inner segment labeled 70 over SFC is Class B airspace extending from the surface up to 7,000 ft MSL, so §107.41 requires ATC authorization before any Part 107 flight there. Staying low does not exempt the flight, because the controlled airspace reaches all the way to the ground in that ring. Class B is not closed to Part 107; authorization is routinely granted through LAANC or DroneZone where facility maps allow it.
