Study Notes

Class D Airspace

Appears on maps with a blue dotted line.
Extends from the surface up to 2,500 feet above an airport with an operational control tower.
The "D" signifies Dime Sized or Diminutive airports.
The ceiling is indicated by the number of brackets on aeronautical charts.
For example, 42 brackets mean a ceiling of 4,200 feet MSL.
Class D airspace starting at the surface up to 2,000 feet is represented as [-20].

Control Tower Operations

If the control tower is closed, Class E surface area rules apply, combined with Class G rules down to the surface.
Upon the control tower ceasing operation, the airspace reverts to Class E or a combination of Class E and G airspace.

Class E Airspace

Comprises eight types of airspaces.
Present on maps as a magenta dotted circle.
Authorization to fly in Class E may be necessary if it extends from Class B, C, or D.
Class E starting at 700 feet AGL appears as thick, magenta shaded "fuzzy" circles.
Class E starting at 1,200 feet AGL is not depicted on maps; knowledge of the airspace is required.
Can begin from the surface, 700 feet AGL, or 1,200 feet AGL.

Class G Airspace

Known as uncontrolled airspace, it includes regions not designated as Class A, B, C, D, or E.
sUAS operators can fly in Class G without prior authorization, unlike in controlled airspaces which require permission.
