Airspace Classification Flashcards
Controlled
A B C D E
Uncontrolled
F G
Controlled Airspace can be defined as?
Airspace of defined dimensions within which and air traffic control service is provided in accordance with the airspace classification (SERA 923/2012)
Class A?
IFR Only. ATC service & separation to all flights
Class B?
IFR/VFR. ATC service & separation to all flights
Class C?
IFR/VFR. ATC service to all flights. IFR separated from all traffic. VFR separated from IFR & recieve traffic info on other VFR flights.
Class D?
IFR/VFR. ATC service to all flights. IFR separated from IFR & receive traffic info on VFR. VFR receive traffic info on all other traffic.
Class E?
IFR/VFR. IFR receives ATC service & separated from IFR. All flights receive traffic info where practical.
Class F?
IFR/VFR. IFR receives traffic advice if requested
Class G?
IFR/VFR. No ATC standard. Advisory services available. All airspace above FL660
Control Zone (CTR)?
Controlled airspace extending upwards from the surface of the Earth to a specified upper limit (ICAO Doc 4444)
Control Area (CTA)?
Controlled airpsace extending upwards from a specified limit above the Earth (ICAO Doc 4444)
What is the difference between a control zone and a control area?
Control zones extend upwards from the surface of the Earth, whereas a control area will usually sit above this, extending upwards from a specified limit or designated base.
Terminal Control Area (TMA)?
Control area normally established in the vicinity of one or more major aerodromes (SERA 923/2012)
Air Traffic Service Route (ATS Route)?
A specified route designed for channelling the flow of traffic as necessary for the provision of ATS (SERA 923/2012). Pilots will usually fly along a defined route such as airways to or from significant waypoints.
Airway (AWY)?
A control area or portion thereof established in the form of a corridor (923/2012).
What are the standard dimensions of an airway in the UK?
10nm wide from a DB to FL245
Upper Air Traffic Services Routes
A specified route above FL245 designed for channelling the flow of traffic as necessary for ATS. Routes usually have a designated centre line which aircraft usually fly within 5 miles either side
Standard Instrument Departure (SID)
A designated IFR departure route linking the aerodrome or specified runway of aerodrome with a specified significant point, normally on a designed ATS route, at which the en route phase of a flight commences (ICAO 4444)
Standard Terminal Arrival Route (STAR)
A designated IFR departure route linking a significant point, normally on an ATS route, with a point from which a published instrument approach procedure can be commenced (ICAO4444)
Aerodrome Traffic Zone (ATZ)
airspace of defined dimensions established around and aerodrome for the protection of aerodrome traffic
What are the standard dimensions of an ATZ?
Usually a 2 or 2 1/2 nm radius circle centred on the notified mid-point of the longest runway, and vertically to 2000ft
What is the difference between an ATZ and a TMA?
An ATZ is a very localised protected area surrounding an aerodrome whereas a TMA may be established at the vicinity of one or more major aerodromes. A TMA is controlled airspace, an ATZ is not considered controlled airspace but is situated within a CTR.
