Airspace & ChartsCâu 45 / 100
A sectional chart shows a towered airport ringed by a segmented blue line, with a boxed bracketed notation printed as 25 next to the ring. What does that notation tell the remote pilot?
a.The airport control tower remains in operation until 2,500 local time each day
b.The controlled airspace around the airport tops out at 25,000 ft MSL
c.The floor of the airspace is 2,500 ft MSL, with uncontrolled airspace below it
d.The Class D airspace extends from the surface up to and including 2,500 ft MSL
Giải thích
A bracketed number beside a Class D ring is the ceiling of that airspace in hundreds of feet MSL, so 25 means the Class D extends from the surface up to and including 2,500 ft MSL. Class D areas always begin at the surface, so the notation cannot be describing a floor. It is an altitude, not a time of day, and 25,000 ft would be printed as 250.
