Installation & Licence key
Execute LotAtc 4 DCS client. After loading, a “Not connected” message will appear. Click on the [Connect] button of the main menu bar, you’ll get this:
Enter the address (IP or URL/DNS) of the server you want to connect to, set the TCP port if using a non-default one (default port is 10310; LotAtc uses TCP only).
Choose your coalition by clicking on the blue or red square (active coalition is highlighted), then enter the password needed to access the chosen coalition (passwords are set by the server; ask the host what he set).
Default password are: “blue” for the blue coalition, and “red” for the red coalition. And yes, we won an imagination contest with that (a long time ago).
Finally, enter your Pseudonym (will be displayed when using the chat feature).
Then, click on the [Connect] button of the connection window. Once the connection is established, you will be notified by LotAtc displaying the following things:
- A non-persistent message saying “Connection and authentification OK” (top right of the radar display),
- Your pseudonym and the active detection profile at the top right of the main UI bar, and said bar will be lightly colored (the color of the pseudo and the bar depends on the coalition you’re connected to).
- The map is active (“bright” colors) and the geographical coordinates of the mouse cursor are dispayed in the bottom left corner of the radar screen.
Seconds later, if the DCS server is un-paused, the picture (tactical situation) and mission data should appear on your screen. Now, you’re an active controller: it’s time to work!
Remember that what you can see depends of the detection profile set by the server.
Using LotAtc client
What does LotAtc show up?
Well, it displays, over a map (background), the units detected in the DCS mission. Which units are shown depends on the detection profile enforced by the server and, of course, the tactical situation at the time. The radar screen is refreshed every 2 seconds by default.
By default, friendly units (= from your coalition) are shown in white, and enemy coalition units are displayed in red. See below how to change that if you wish.
LotAtc is able to display:
- Mission data, with:
- current weather (only if static weather - we’re looking what’s possible with dynamic weather, but at this time the answer is ‘nothing useful’)
- time from DCS
- bullseye position (your coalition’s one only, of course)
- geographical coordinates, position relative to the bullseye, and elevation of the point at the mouse cursor location.
NB: elevation requires the relief database installed; this database is automatically installed if you have LotAtc 4 DCS server module, or you can choose to download and install it when installing LotAtc 4 DCS client stand-alone application.
- Aircraft units, with:
- a symbol that may vary depending on the detection profile enforced by the server, the nature or mission of the aircraft, or simply the controller’s choice (you or another colleague logged on the same coalition),
- a velocity vector showing where the aircraft is headed for; the lenght of the vector is either:
- showing where the aircraft will be in X seconds if it doesn’t change course nor speed
- or proportional to the aircraft ground speed measured by LotAtc,
- a customizable label with various data about the aircraft (see the labels page for more details).
- Ground and Sea units, with:
- a SAM symbol for Ground units, or a ship symbol for Sea units,
- a label indicating their type, displayed only when you’re hovering your mouse cursor above the symbol.
- Detection and Engagement circles, with:
- the detection circle (discontinuous line) that allows the ATC/GCI to assess units max detection range (AWACS, ground- and sea-based radars),
- the engagement (threat) circle (continuous line) that allows the ATC/GCI to assess units max engagement range (ground- and sea-based SAMs).
- You may hide those circles if needed to declutter your radar screen: See ‘Key shortcuts’ below.
Above ARCADE profile, the engagement (threat) circle is displayed only if the launcher is the same vehicule as the radar. LotAtc simulates an ESM capability, and you cannot know where precisely is a launcher if it doesn’t emit radar waves. Please refer to the [[Detection Profiles]] page to learn more about what types of SAMs (and their circles) are displayed or not, and why.
Let’s see a simple example:
Here, we see an aircraft taking off from Sochi Adler RWY 24, a SAM protecting the airbase, and a ship loitering off the coast. All the units are white, which is the default color for friendly units (ennemies are red by default); this means here they all belong to our side (our coalition).
On this image, the green texts and arrows are legends. Those do not actually show up in LotAtc.
Your mouse is your most used tool in LotAtc 4 DCS. Use it to:
- Move the map: Left click + drag
- Zoom the map: Mouse wheel
- Display an aircraft’s ‘detailled’ (hovered) label: Hover your mouse cursor over its label
- Display a ground or sea unit’s type label: Hover your mouse cursor over its label
- Rotate an aircraft label by 45° increments around its radar plot (to declutter the display):
- Maintain [Shift] and Left click on the label or the aircraft symbol for clockwise
- Maintain [Shift+Control] and Left click on the label or the aircraft symbol for anticlockwise
- Display and Set the properties (name, symbol) of a displayed unit: Left click on the unit then use the Properties panel on the right side of your display (this is not available in ARCADE profile)
- Draw a bearing/range calculation line: Right click+drag
- Draw a persistent BRAA: Ctrl+right click
- Left click in mouse cursor data area (bottom left of map) to reduce it
About the latter feature, which is most useful for tactical controllers, here is how it looks:
Again, on this image, the green texts and arrows are legends and do not actually show up in LotAtc.
Key shortcuts allow controllers to change some settings instantly, without having to dig into the option menu:
|Alt+N||Change unit system metric/imperial|
|Alt+C||Show/hide detection/threat circles|
|Alt+L||Show/hide labels background|
This is where you’ll choose what language LotAtc 4 DCS should use. Restarting LotAtc is mandatory for any change made here to be applied.
Thanks to volunteer members of the community, several languages are now available for LotAtc 4 DCS client. Thanks to all involved!
Please refer to the languages page for more details, including the list of available languages at this time.
The map option menu allows you to choose which map is used as a background for LotAtc 4 DCS radar display.
You may choose between four maps:
|classic||default map; it shows land/sea, main lakes and urban areas|
|simple||same as the default one, but without urban areas|
|green||same as the simple one, but land is green instead of dark grey|
|relief||it shows the relief of the terrain, the main lakes/rivers, and states borders|
LotAtc is built to allow more maps to be easily included. This will be documented later.
The items option menu allows you to set LotAtc symbology principles.
Here you’ll be able to:
- cycle between the “AWACS” and the “French” sets of symbols (to display different aircraft/missions) (see detection profile for more details about available individual symbols)
- set the colors you want to use for friendly and enemy units (defaults are: Friendly = White / Enemy = Red)
- set the size of the symbols (change it if symbols are too tiny to be read on your screen; default size is 15)
- configure how you want the aircraft speed vectors to be displayed between:
- the zoom independent mode (slider fully to the left), where the speed vector lenght is relative to the measured ground speed of the aircraft, and independent of the zoom of the map
- the time mode, where the far end of the speed vector shows where the aircraft will be in X seconds (set X with the slider); by nature, the speed vector lenght then varies depending on the zoom level.
This option allows you to set what data the aircraft labels will display.
See the labels page for more details about this.
The [news] button opens a window displaying last news from the developper. There will be announced the version upgrades. The news are also visible on the LotAtc website
