Flashcards in Airspace Deck (38)
What is Class A airspace?
18,000 ft and up to and including FL600. No VFR flights can be conducted in Class A airspace. You must be a private pilot with an instrument rating.
What min equipment is required for flight operations in Class A airspace?
a) Two-way radio capable of communicating with ATC
b) A Mode C transponder
c) IFR equipped aircraft
What is Class B airspace?
Airspace from the surface to 10,000 ft MSL surrounding the nations busiest airports. "B" for BIG. Class B airspace areas resemble upside down wedding cakes for instrument procedures.
What is the min equipment required to fly in Class B?
a) Two-way radio for ATC communication
b) Mode C transponder
c) An operable VOR or TACAN receiver
You must have ATC clearance to enter Class B airspace.
What are the Wx min for VFR flight in Class B?
Clear of clouds with at least 3 miles visibilty
What basic services are provided to pilots in the Class B airspace?
VFR pilots will be provided with sequencing and separation from other aircraft.
What is the max speed allowed when operating inside Class B airspace, under 10,000 ft and within a Class D surface area?
No person may operate an aircraft at or below 2500 ft above the surface within 4 nautical miles of the primary airport of a Class C or Class D airspace area at an indicated airspeed of more than 200 knots.
When operating below the lateral limits of Class B airspace, or in a VFR corridor designated through Class B airspace, what max speed is authorized?
What is Class C airspace?
Airspace from the surface to 4000 ft above the airport elevation (charted in MSL). 5 nautical mile radius core surface area up to 4000 ft and a 10 NM radius shelf area that extends from 1200 ft to 4000 feet above the airport elevation. The outer radius will be 20 NM with some variations based on site specific requirements.
Must have a Mode C transponder and a two-way radio.
Must "establish" two-way radio communications the ATC facilities prior to entering and must maintain those communications while within that airspace. Controller must identify your aircraft callsign to be established.

What are the min wx conditions for flying in Class C airspace?
3 Statute miles, 500ft below, 1000ft above, 2000ft horizontal to clouds.
Where is mode C altitude encoding transponder equipment required?
a) At or above 10,000 ft MSL excluding airspace below 2500 ft AGL.
b) Within 30 miles of a class B airspace primary airport below 10,000 ft MSL
c) Within and above all Class C airspace, up to 10,000 Ft MSL
d) Within 10 miles of certain designated airports, excluding that airspace which is both outside CLass D surface area and below 1200 ft AGL
e) All aircraft flying into , within, or across the continuous US ADIZ.
What is the max airspeed in Class C?
200 knots (230MPH)
What is Class D airspace?
Extends from the surface to 2,500 ft above the airports elevation in MSL. Each person must establish two-way radio communications w/ the ATC facilities providing air traffic services prior to entering that airspace.
What are the wx mins for Class D airspace?
3 statue miles, 500 feet below, 1000 above, 2000 horizontal of clouds
What is the max airspeed in Class D?
200 knots (230 MPH)
Explain the purpose of Class E transition areas
Class E transition areas extend upward from either 700 ft AGL or 1,200 ft AGL and are designated for airports with an approved instrument procedure. Class E transition areas exist to help separate (via cloud clearance) arriving and departing IFR traffic from VFR aircraft operating in the vicinity. These are depicted on the charts as segmented magenta lines.
Are you required to establish communications with a tower within Class E airspace?
Yes. Communications must be established prior to 4 nautical miles from the airport, up to and including 2,500 ft AGL.
What is the definition of Class G airspace?
Uncontrolled airspace that has not been designated as Class A, B, C, D or E airspace. ATC has no authority or responsibility to control air traffic.
Are you required to establish communications with a tower located within Class G airspace?
Yes. 4 miles prior
What are the vertical limits of Class G airspace?
Class G airspace begins at the surface and continues up to the overlying controlled (Class E) airspace, not to exceed 14,500 ft MSL.
What is the min cloud clearance and visibility required when conducting flight ops in a traffic pattern at night in Class G airspace below 1200 AGL?
When the visibility is less than 3 SM and not less than 1
SM during night hours, an aircraft may be operated clear of clouds if operated in an airport traffic pattern within 1/2 mile of the runway.
What are the "basic" VFR wx min required for operation of an aircraft into Class B, C, D, or E airspace?
1,000 ft ceilings and 3 miles visibility.
If VFR flight minimums cannot be maintained, can a VFR flight be made into Class B, C, D, or E airspace?
No, with one exception. A special VFR clearance may be obtained from ATC prior to entering the airspace provided the flight can remain clear of clouds with at least one statue mile ground visibility if taking off or landing.
If it becomes necessary to obtain a special VFR clearance, what facility should the pilot contact in order to obtain one?
Control tower or if in E airspace, FSS or center
What is a "prohibited area"?
Prohibited areas contain certain airspace of defined dimensions identified by an area on the surface of the earth within which the flight of aircraft is prohibited. Such areas area established for security or other reasons associated with the national welfare.
What is a "restricted area"?
Restricted areas contain airspace identified by an area on the surface of the earth within which the flight of aircraft, while not wholly prohibited, is subject to restrictions. These areas denote the existence of hazards to aircraft such as artillery firing, aerial gunnery, or guided missiles.
Under what conditions may pilots enter restricted or prohibited areas?
Must have permission from controlling agency. Must have prior permission.
What is a "warning area"?
A warning area is airspace of defined dimensions extending from three nautical miles outward from the coast of the US, containing activity that may hazardous to nonparticipating aircraft. May be located over domestic or international waters.
What is a "MOA"?
Military Operating Area. Consists of airspace of defined vertical and lateral limits established for the purpose of separating certain military training activities from IFR traffic. Pilots operating under VFR should exercise extreme caution while flying within an MOA when military activity is being conducted. Pilots should contact any FSS within 100 miles of the area to obtain accurate real-time info concerning the MOA hours of operation.
