ICAO Doc 4444 Quiz: Chapter 4 Overview

Air traffic control provided over a large area.

A facility responsible for providing area control service.

Air traffic control provided in a designated airspace near an airport.

A designated airspace around an airport where air traffic control services are provided.

A designated airspace where air traffic control services are provided, but smaller than a control zone.

The unit responsible for providing approach control service when no ACC is established.

The unit providing approach control service can provide area control service in a control area of limited extent if no ACC is established.

When necessary or desirable, approach control service can be combined with the functions of an aerodrome control tower or an ACC into a single unit, ensuring coordinated control.

When necessary, approach control service is established as a separate, dedicated unit, focusing solely on the approach phase of aircraft operations.

An aerodrome control tower is responsible for providing air traffic control services within the designated airspace of an airport, ensuring safe and efficient operations within the airport environment.

An air traffic control unit, typically a specialized facility, responsible for providing flight information and alerting services to aircraft within a defined airspace region.

Flight information and alerting services are provided by relevant air traffic control units within controlled airspace and at controlled airports, ensuring safe and efficient flight operations.

A designated airspace region where air traffic control services, including flight information and alerting, are provided, covering a large geographic area.

When a flight information center is not in place, the responsibility for providing flight information and alerting services can be handed over to an air traffic control unit with adequate resources and capabilities to handle these tasks.

A controlled airspace where air traffic control services are provided, ensuring the safety and separation of aircraft within a defined area.

The authority responsible for air traffic control, including designating areas of responsibility for ATC units and their individual sectors.

A designated area where an ATC unit provides air traffic control services, such as approach or area control.

Different ATC units often have overlapping responsibilities for different phases of flight. This specifies how responsibility is divided between units.

The control of aircraft arriving at and departing from an airport is usually split between aerodrome and approach control units. This term specifies how.

For arriving aircraft, the aerodrome control unit is responsible for control until the aircraft is within the approach control area, where the approach control unit takes over.

The duties and responsibilities of each individual ATC working position within a unit or sector are clearly defined.

When there are multiple ATC working positions within a unit or sector, the duties and responsibilities of each individual position are clearly defined.

The control of controlled flights is divided between aerodrome and approach control units, with clear guidelines to ensure smooth transitions.

Transfer of control from aerodrome control to approach control when visual conditions prevail, based on aircraft's location relative to aerodrome and predefined points or levels specified in agreements or instructions.

Transfer of control from aerodrome control to approach control when instrument conditions prevail, based on aircraft's takeoff or reaching specified points or levels outlined in agreements or instructions.

Responsibility for controlled flights outside an area control center (ACC) lies with the area control service. However, approach control takes over responsibility for arriving aircraft released by the ACC and departing aircraft until they are released to the ACC.

When an aircraft leaves the vicinity of the aerodrome, it transitions from aerodrome control to approach control. The specific timing depends on weather conditions and predefined points or levels in instructions.

Approach control takes over responsibility for departing aircraft until they are handed over to the area control center (ACC).

Transferring control from Approach Control to Aerodrome Control when the aircraft is close to the airport and can visually land.

The aircraft is close to the airport and can visually land.

A designated point or altitude where control is transferred from Approach Control to Aerodrome Control.

The unit responsible for providing air traffic control services within a designated airspace around an airport.

The unit responsible for providing air traffic control services to aircraft approaching an airport.

The unit that provides guidance and instructions to arriving aircraft before they reach the approach control service.

When control is transferred from Approach Control to Aerodrome Control, ensuring timely clearance for landing or alternative instructions and information about local traffic.

Agreements outlining procedures for handing over control between different air traffic control units.

The unit responsible for providing Air Traffic Control within a large area.

Direct control transfer from ACC to Aerodrome Control or vice versa, in certain situations.
