Question 11

Control Zone (CTR)?

Answer 11

Controlled airspace extending upwards from the surface of the Earth to a specified upper limit (ICAO Doc 4444)

Question 12

Control Area (CTA)?

Answer 12

Controlled airpsace extending upwards from a specified limit above the Earth (ICAO Doc 4444)

Question 13

What is the difference between a control zone and a control area?

Answer 13

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.

Question 14

Terminal Control Area (TMA)?

Answer 14

Control area normally established in the vicinity of one or more major aerodromes (SERA 923/2012)

Question 15

Air Traffic Service Route (ATS Route)?

Answer 15

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.

Question 16

Airway (AWY)?

Answer 16

A control area or portion thereof established in the form of a corridor (923/2012).

Question 17

What are the standard dimensions of an airway in the UK?

Answer 17

10nm wide from a DB to FL245

Question 18

Upper Air Traffic Services Routes

Answer 18

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

Question 19

Standard Instrument Departure (SID)

Answer 19

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)

Question 20

Standard Terminal Arrival Route (STAR)

Answer 20

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)

Question 21

Aerodrome Traffic Zone (ATZ)

Answer 21

airspace of defined dimensions established around and aerodrome for the protection of aerodrome traffic

Question 22

What are the standard dimensions of an ATZ?

Answer 22

Usually a 2 or 2 1/2 nm radius circle centred on the notified mid-point of the longest runway, and vertically to 2000ft

Question 23

What is the difference between an ATZ and a TMA?

Answer 23

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.
