Airspace Flashcards
Name all the different airspaces
A, B, C, D, E, G
Class A elevation
18,000 MSL up to FL 600 (60,000ft)
&
Over water within 12NM of the US0
All flights are to be conducted under IFR
Describe Class B
Surface to 10,000 MSL.
Surrounds nations largest airports
Made from surface and 2 or more airspace regions
Must have ATC permission to operate in the area
Describe Class C airspace
- Surface to 4,000ft above the airport elevation around an airport with an operating control tower
- Surfaced by a radar approach control
- Have a certain number of IFR operations or passenger enplanements
- Individually tailored but are generally 5nm from the airport to 4,000ft and a ring from 5-10nm that exists from 1200ft to 4,000ft above the airport elevation
- Must maintain 2-way radio communication with ATC
Describe Class D airspace
- Usually extends from surface to 2,000ft above airport
- Must maintain 2-way radio communication with ATC
- Tailored if instrument procedures are published
Describe Class E airspace
- If airspace is not A, B, C, D but it is still controlled
- Extends upwards from either the surface or a designated altitude to the overlying or adjacent controlled airspace
- When given a surface area, it is meant to contain all instrument procedures
- Federal airways which begin from either 700 or 1200 AGL and are used to position to and from terminal areas or in root environments
- Begins over the united states at 14,000 to 18,000ft MSL
Describe class G airspace
- All airspace that is not A,B,C, D, E
- ATC has no authority in this area but there are VFR minimums that apply
Describe Special Use Airspace
Activities must be confined or limitations are imposed on aircrafts that are not part of these activities
-Includes: prohibited areas, restricted areas, warning areas, military operating areas, alert areas, controlled firing areas
Describe the symbol for prohibited areas on a map. Describe what prohibited areas are.
- Circle with lines pointing inward on the inner part of the circle
- Flight by aircraft is prohibited. Can be established for security or national welfare reasons. Examples include Camp David and National Mall in Washington DC
Describe restricted areas
These areas do not totally prohibit aircraft operation but restrict aircraft when the area is in use. The often pose invisible hazards to pilots when in use -ie guided missiles, artillery firing, or aerial gunnery
What is a warning area on a map?
Airspace of defined dimensions extending from 12nm outward from the coast of the US containing activity that may be hazardous to non-participating aircraft. Area is not directly controlled by the FAA and is a warning to non-participating pilots
Describe alert areas on a map
Designed to inform non-participating pilots of areas of high volume pilot training or an unusual type of arial activity
Describe controlled firing areas
Do not need to be charted because activities are suspended when aircraft are in the vicinity
List some other types of airspaces
- Military Training Routes (MTR), typically below 10,000ft but above 1500ft, speeds in excess of 250kts
- Temporary Flight Restrictions - Temporary restrictions around areas to protect people and property from damage, or make areas less congested for emergency aircraft
- Parachute Jumping Activity
- Published VFR Routes - routes that transition under, around, or through complex airspace
- Terminal Radar Service Areas - areas that provide separation between all IFR and participating VFR aircraft
- National Security Areas - Airspace that provides increased security and safety of ground facilities
Describe the primary purpose of ATC?
Prevent collision between aircraft operating in the system and to organize and expedite the flow of traffic
