Q

What is an Aerodrome Control Zone?

A

An area of control airspace which provides protection to aircraft within the immediate vicinity of an aerodrome.

17
Q

What is a Control Area/Terminal Control Area?

A

Situated above Aerodrome Traffic Zones (ATZ), these give protection to a wider area up to a specified upper limit. These are established at the junction of airways in the vicinity of one or more major aerodrome. London Terminal Control Area is an example of this.

18
Q

What is an Airway?

A

An airway is a corridor of airspace connecting Terminal Control Areas and linking up with the airways of other countries. Airways are normally 10 miles wide, and range from 5,000-7,000ft up to a height of FL245 (24,500ft).

19
Q

What is an Upper Air Route (UAR)?

A

Sit above airways, their vertical limits are usually FL250 (25,000ft) up to FL460 (46,000ft). Civil and Military aircraft operating above FL245 (24,500ft) are subject to full and mandatory Air Traffic Control service.

21
Q

What restricted airspace sits directly above an Aerodrome Control Zone?

22
Q

What restricted airspace connects Terminal Control Areas and other countries?
