Airspace Basics (20-25 Cards) Flashcards
(20 cards)
What are the 6 main classes of controlled/uncontrolled airspace in the U.S.?
Class A, B, C, D, E (controlled), and G (uncontrolled).
What altitude does Class A airspace start and end at?
From 18,000 ft MSL up to FL600 (60,000 ft).
What are the VFR weather minimums in Class A airspace?
VFR is not allowed in Class A; IFR only.
What is required to enter Class A airspace?
IFR flight plan, clearance, instrument rating, Mode C transponder.
What is Class B airspace typically shaped like?
An upside-down wedding cake (multiple layers/shelves).
What equipment is required to fly in Class B?
Mode C transponder, two-way radio, and clearance to enter.
What is the typical altitude range of Class B airspace?
Surface up to 10,000 ft MSL, varying by airport.
Can student pilots fly in Class B?
Only with proper training and instructor endorsement.
What is required to enter Class C airspace?
Two-way radio contact (ATC must say your callsign).
What is the typical shape of Class C airspace?
5 NM radius core (surface to 4,000 ft AGL) and 10 NM shelf (1,200 to 4,000 ft AGL).
What equipment is required in Class C?
Two-way radio, Mode C transponder.
How is Class D airspace depicted on a sectional chart?
Blue dashed circle.
What is required to enter Class D airspace?
Two-way radio contact.
What is the typical altitude of Class D airspace?
Surface to 2,500 ft AGL.
When does Class D airspace revert to Class E or G?
When the control tower is closed.
How is Class E airspace depicted above 1,200 ft AGL on sectional charts?
Faded magenta shading.
What are the VFR weather minimums for Class E below 10,000 ft MSL?
3 SM visibility, 500’ below, 1,000’ above, 2,000’ horizontal from clouds.
What is Class G airspace?
Uncontrolled airspace; typically below 700 or 1,200 ft AGL.
Are ATC services available in Class G airspace?
No, but pilots may monitor CTAF at nearby airports.
How is Class G airspace depicted on a sectional?
It is implied - outside of controlled airspace boundaries.
