This document describes the IVAO ATC Software at the initial version:

  • Aurora 1.1.62 BETA

Main Aurora View

When opening ATC Client, the screen has three (3) main sections: Title Bar, Options, and Main Radar Screen.


Here we see the following information:

  • ATC Client version
  • Callsign, or last used profile (when not online)
  • Distance (in nm), Track/Reverse Track, Latitude and Longitude, all this in relation to the centre point.
  • Zoom level
  • Time (UTC)
  • On active ATC positions, the METAR is also displayed for the station

ATC Client Manual - Title Bar.png


This section is split into two (2) option bars: Preferences and Menu.

ATC Client Manual - Options Bar.png


This menu has eight (8) options:

  • Connect / Disconnect
  • ATIS
  • COM
  • ATC
  • PVD
ATC Client Manual - Menu Bar.png


When pressing CONNECT, a new window is displayed; this is where you will insert your station callsign, network credentials, first and last name, and select appropriate network and voice servers.

After connecting, the Connect button changes to “Disconnect”. We need to press Disconnect before closing our ATC Client, to ensure that Network Servers do not hold a “Ghost Connection”.


In real life, ATIS is a continuous broadcast of automatic or recorded voice, on a specific VHF frequency or via the vocal channel of a radio-navigation beacon. It contains essential information, such as weather information (METAR), active runways, available approaches, NOTAM, and any other information required by pilots.

At IVAO, we have adapted our ATIS information for pilots, due to the current network/technology limitations:

  • Each ATC position has its own ATIS
  • ATIS is written in text, by the controller, in a predefined form
  • Pilots can only read ATIS information as text when tuning the ATC frequency or sending the appropriate command to the server
  • ATIS contains the TeamSpeak (voice) server info in the first line.
ATC Client Manual - ATIS Window.png


When pressing the COM button, it opens a new window, where we have our main text communication.

The COM Box may have up to eight (8) tabs:

  • The first tab represents your MAIN frequency. You can change this frequency using “// xxx.xxx” where the x's will be replaced with your frequency.
  • Second and Third tab represent other frequencies that you can use to “monitor”. For example, you can set UNICOM (122.800) or another ATC frequency. These additional frequencies can be set in PVD -> Settings window. Like the primary frequency, you can change these with “// xxx.xxx”.
  • “GUARD” tab represents the emergency frequency, 121.500. When a pilot changes his main frequency (COM1) to 121.500 and sends a text message, this message will be delivered to all near pilots, no matter the main frequency they have tuned, and to nearby online ATC.
  • “ATC” tab is for online ATC coordination. It works as a text intercom.
  • “BRDCST” tab means Broadcast. Supervisors can send messages to the whole network. These messages arrive in this tab.
  • “MSG” tab means Messages. In this tab, messages arrive from the server; Force Act sent response and COM checks are examples.
  • “PRIVATE” tab. Here you can view and send private messages with different stations (ATC, Pilot, or Observers).
ATC Client Manual - COM Window.png


When pressing the ATC button, it opens a new window, where we can see ATC or Observers online, near our station (based on Range and Center Point). Here, you have five (5) columns:

  • Call, which is the Callsign
  • Freq, which is the primary frequency of the station
  • R, which means the ATC rating
  • Name
  • Options
    • C = Controlling: if ATC position is active, it will be white
    • T = Transfer List: if marked (white), this station will be available in your transfer list
    • M = for sending a private message
    • A = to request ATIS of the station, as a private message
ATC Client Manual - ATC Window.png


In this window, we have a general/basic flight strip display with information regarding the selected aircraft.

The first column shows SCEL as the destination, I as IFR flight, then 2000 for the transponder code selected by the pilot.

The second column shows F380 as final Flight Level (FL), LJ45 M as aircraft type and category, M082 as speed, and SAME as the alternate airport.

The third column shows AFR167 as the aircraft callsign, and Air France as a reminder for the radio callsign, SUMU as the departing airport, and 1650 as the departure time.

The fourth column shows the Flight Plan (FPL) route, and underneath is the other info or remarks section (Item 18 of FPL).

ATC Client Manual - Traffic Window.png

In addition to the above description, at the bottom there is a row where ATC can write information into the aircraft TAG:

  • WP as waypoint or text, with a maximum of XX characters.
  • ALT as Altitude
  • SPD as Speed

Writing information in any of these boxes, and then pressing the “tick” button or just hitting “enter” on the keyboard, will send the information. When pressing the “DEL” button, the information will be removed from the aircraft tag.

There is a SQK box, meaning Squawk (Transponder), where ATC can assign a transponder code, so when selecting a new aircraft, and hitting the NEXT button, the client will automatically assign a new transponder code, based on the last one used.

The PM Button will open a private chat tab in the COM window, to talk with the pilot in private.

The TRFC LIST button expands the TRAFFIC window and will display aircraft based on the buttons selected below: DEP for Departures, ARR for Arrivals, OVER for Overfly, and UNCO for uncontrolled (not assumed). All this will be based on what is selected in the AIRPORTS window.

ATC Client Manual - Traffic List Window.png


The window is split into two main columns, where the one on the left displays airports, based on sector file information. When an airport is selected in the list underneath, full METAR for that station (if available) will be displayed. In addition, for those stations with a valid METAR, QNH and wind information will be shown.

When controlling an airport, or more, first you must select that airport “as controlled” by clicking the funnel in the C column. You can select the “crossed runways” icon (R), to let the system choose the active runway automatically. The magnifying glass icon (Z) will focus the main radar screen over that airport. The V column is for toggling on the VFR waypoints for that airport and the M column for toggling the MRVA.

The right column is split into two sections. The top section refers to runways of the selected airport (on the left). RWY indicates Runway number, CRS indicates Runway course (magnetic). P shows advise on which runway should be selected for the active runway (automatically selected by the system), D is where you can set the departure runways and A to select the arrival runways.

Profiles are text files where different settings are saved, to make save setting everything again, the next time you log on. When pressing this menu option, a dropdown list with three (3) options is shown:

  • Open, lets you select a profile.
  • Save (Key Shortcut: F4), lets you save the current profile (the name of the profile will be the station callsign currently used).
  • Supervisor (Key Shortcut: F3), opens the Supervisor module (Appendix to this document).

ATC Client Manual - Profile Menu.png

It’s important to note, that the system will not save the profile when exiting, so make sure to press F4 each time you make an important change (FIX selection, zoom, etc), so the profile will be saved.


This menu section will let you change different settings, displayed in a dropdown list:

ATC Client Manual - PVD Window.png

  • SECTOR (Key Shortcut: F1): Opens the Sector File window where you can download (right column) or load (left column) the local sector file by pressing the folder icon.
