ACAS (Airborne Collision Avoidance System)

Anti-collision system on board aircraft. It is activated when two aircraft fail to respect separation minima. (–> RA, TA, TCAS)

ACC (Area Control Center)

Responsible for the safe flow of traffic along airways (–> En-route) and in certain portions of terminal control areas (–> APP). Significant horizontal and vertical growth in the areas to be controlled requires subdivision into various sectors of activity, either geographically or according to altitude, depending on traffic density.

ADDC (Air Defence and Direction Center, EZ or “Einsatzzentrale” in German)

Skyguide’s military ATCOs based in the ADDC in Dübendorf are responsible for a variety of tasks: determining the general situation of airspace, airspace security, training formation flights for air forces (air defence) and providing ATC for all civil and military aircraft entrusted to it outside of the control area of military aerodromes. From an organisational standpoint, the fact that military ATC services are provided by a civil enterprise is unique in the West. (–> Integration)

ADS (Automatic Dependent Surveillance)

AIC (Aeronautical Information Circular)

Used to provide administrative information which does not involve restrictions on aviation, for example, verification data for the awarding of a pilot’s licence, etc.

AIG (Aéroport International de Genève or Geneva International Airport)

Air traffic control there is handled by skyguide. (www.gva.ch) (–> Geneva Cointrin)

AIM (Aeronautical Information Management)

In accordance with Eurocontrol recommendations, AIM handles the ever-increasing aviation information flow. As an enlarged redefinition of AIS (–> AIS/AIM), AIM allows for the provision of homogeneous, standardised and efficient digital information during all flight phases and for all European services involved. (aim(at)skyguide.ch)

AIP (Aeronautical Information Publication)

Basic document for pilots, ATCOs, airlines, airports, etc. used to prepare and ensure safe flight operations. It contains the most important statistical data and aeronautical charts for aviation. The Swiss AIP is published by skyguide.

AIRPROX (Aircraft Proximity)

A situation in which the separation minima required between in-flight aircraft for safe operations are not respected. (–> ATIR)

Airspace

A three-dimensional space criss-crossed by airways. In keeping with ICAO rules, worldwide airspace is subdivided into various classes. The provision of air traffic control is defined for each class, together with the applicable flight rules (–> DELTA, UAC). A distinction is made between civil and military airspace; each of these is primarily reserved for one user group. Since integration, skyguide manages all of Swiss and some foreign delegated airspace, and in so doing improves both flexibility of use and capacity.

Airspace management

A system of management which takes into account user needs and optimises the use of airspace by improving its structure and by designating airways and specifying the ATM procedures to be followed.

Air Traffic Control (ATC)

A collective term for all the services provided to ensure the safe, orderly and cost-effective flow of air traffic through controlled airspace and to make sure that the separation minima between aircraft are respected. It is subdivided into aerodrome control (–> TWR), approach or terminal control (–> APP) and area control (–> ACC).

Air Traffic Controller (ATCO)

Manages and monitors, from the airport of take-off to that of landing, all of the aircraft present in the portion of airspace for which he or she is responsible. Skyguide employs about 450 civil ATCOs and 90 military ATCOs. The profession of ATCO is open to both men and women. (–> STC)

Air Traffic Management (ATM)

Service unit of ATC operations, the goal of which is to organise air traffic safely, smoothly and cost-effectively. Handles Airspace Management and ATC procedures.

Air Traffic Safety Electronics Personnel

–> ATSEP

Airway

The airways in which controlled flights fly are internationally agreed and represented by geographic coordinates. These coordinates are entered into the FMS and help pilots to find their way. (–> Waypoint, Reporting point)

AIS/AIM (Aeronautical Information Service/Aeronautical Information Management)

Central office providing information and advice to flight crews, airlines and general aviation. Receives data (–> Dynamic data, Static data) necessary to ensure the safe and orderly flow of traffic, and processes and transmits such data. Examples include airspace restrictions, weather information, NOTAMs, overflight or approach clearance, etc. Advises the flight crew or airline before the flight and assists both air traffic control and pertinent ground services. Skyguide operates an AIS and an ARO at Wangen bei Dübendorf

AMIE (AIS MET Information Environment)

A selfbriefing facility in the form of an interactive computer terminal for general aviation flight crews which is located at aerodromes and is developed and maintained by skyguide. Pilots may file their flight plan at any time (–> ARO) and receive weather and ATC information.

ANSE (Air Navigation Services Employee)

There are two kinds of ANSE. The ANSEs at the ACC provide assistance to air traffic controllers in tactical and pre-tactical control operations. They receive, process and transmit notification of planned flights, update flight plan data and print them on flight progress strips ; they are also responsible for determining time-slots (–> Slot). The ANSEs at the AIS issue and evaluate data necessary for flight operations.

ANSP (Air Navigation Service Provider)

Fournisseur de services de la navigation aérienne. Skyguide est le seul ANSP de Suisse.

APP (Approach control)

Approach and departure procedures

There are standardised take-off and landing procedures (–> SID, STAR) at airports and aerodromes equipped to authorise IFR  traffic. These procedures have been developed jointly by skyguide and the airport operator to ensure maximum safety and improved traffic flow, as well as to reduce noise pollution. The procedures are verified and approved by FOCA.

Apron control

Coordinates traffic on the tarmac (parking strips and taxiways) and assigns parking stands to aircraft. This is the responsibility of the airport operator.
