Online Networks

The online network functionality allows to connect to VATSIM, IVAO or other online networks which publish whazzup.txt files. This covers display of information for centers, clients and servers on the map.

Network specific information like user names, active centers/towers, frequencies, flight plans and much more are displayed world wide without limits like distance to the user aircraft.

Note that all related window tabs, menu items and toolbar buttons are hidden if online networks are disabled which is the default.

Access to online networks can be enabled and configured in the dialog Options on tab Online Flying. Predefined options for the well known networks are available as well as freely configurable ones.

Overview of Online Network Functions

Simulator and Online Aircraft Duplicates

Little Navmap fetches data from online networks using an interval of three minutes depending on settings and network.

The program also fetches AI or multiplayer aircraft from the simulator which are updated about two times a second. These aircraft are injected into the simulator by the various online clients so they are visible within the simulator.

Therefore, the user aircraft and other client aircraft can appear duplicated on the map.

Little Navmap tries to remove these duplicates by matching the aircraft registration (simulator) and the client callsign (online network). Aircraft can appear duplicated if this information is not available which is the case for X-Plane. Refer to the configuration of your online network tool how to add this information.

Map Display


Online network clients or their aircraft are displayed on the map using the Online in Flight symbol. This includes simulator aircraft that were recognized as online network clients.

The user aircraft is always displayed using the yellow Small GA or a similar symbol depending on aircraft type and simulator. Use the Show in Search map context menu item to see your own aircraft in the list of online clients.

Information for online aircraft is shown on the tab Online Clients in the Information Dock Window.

All other functionality like context menu, double-click, tooltips, map highlights and other are the same as for the other aircraft.

See Aircraft and Ships in the legend for all symbols.

Online Network Aircraft

Online centers are displayed as circular airspaces in Little Navmap and provide the same functionality as the other airspaces (tooltips, information and more). They can be enabled separately from the other airspaces by using the button Show Online Network Airspaces or menu item Show Online Network Airspaces.

Note that the circles do not represent the real airspaces and are only used to indicate the presence of an active center, tower, ground or other position.

Detailed information for online centers/airspaces is shown on the tab Online Centers in the Information Dock Window.

The following types are available and can be enabled in the drop down menus on the airspace toolbar or sub menu Airspaces:

  • Observer: Circle size is taken from the Visual Range value of the center.
  • Flight Information (Center): Uses Visual Range.
  • Delivery (Clearance): Uses Visual Range.
  • Ground: Shows a circle with a diameter of 10 nm.
  • Tower: 20 nm circle.
  • Approach: 40 nm circle.
  • ACC (Center): Uses Visual Range.
  • Departure: Uses Visual Range.

The size of the circle shapes can be changed in the configuration file. See Online Network Center.

Online Network Client Search

Online Network Center Search

The functionality of the search filters in these two tabs and the result tables are similar to the airport and navaid search. See Search Dock Window for information about search filters, buttons and context menu items.

Online Server Search

Displays all online servers in a table and has no search functionality. You can use the context menu to copy parts of the result table like the IP address.
