OpenRadar: Chat aliases

Back to mainpage


In the next update you can start using aliases. Aliases will expand to predefined texts, may contain known data like wind, active runways etc. and they can take input.

For instance, if you type


you get

D-W794: Welcome to the LFSB area -- please advise LFSB ATC of your flightplan, FGCOM 118.300

or if you type

.tr 010<return>

you get

D-W794: Turn right heading 010

This allows you to use the keyboard more effectively.

This feature can be turned off completely and you can define your own alias prefix (the dot in this example) in respect to the different keyboards.

The current aliases

Here is the list of the aliases with their texts. At first you will remember the most important only, but anyway...

# OpenRadar menu based atcMessages

getoff=Please do not start your session on an active runway - Get OFF runway fast

sqa=Squawk <squawk-next>
sqv=Squawk VFR!
sqi=Squawk IFR!
sqm=Squawk {0.SQUAWK}


This list is a proposal. Please feel free to discuss those aliases in the forum. Let us confirm to a set of aliases which will be released. You may replace them in your installation, but it is your responsibility to keep a copy, next update will bring the original files back.


To allow you to see what you are going to send, aliases require two hits on RETURN: A first RETURN to enter the text. This resolves the alias to the text to be sent. The second RETURN will send it. If you hit ESC, the alias is discarded, also, if you enter an unknown alias, the input blocks, until you correct it or hit ESC.

Chaining (multiple aliases behind each other) is not supported, because stacked aliases with arguments might become too difficult to be accepted, we think.

Tags and Arguments

This is about editing aliases, not about using them.

To add known dynamic data to the aliases, you may use tags.

Tags like <icao> resolve to known data:

<icao>               Local departing airport
<icao-altitude>      Local departing airport altitude
<alt>                Aircraft's current altitude
<distance>           Aircraft's current distance to local airport
<callsign>           ATC callsign.
<aircraft>           Aircraft's callsign
<com0>               ATC primary frequency
<com1>               ATC secondary frequency
<winds>              Current winds
<wind-direction>     Current winds direction
<wind-speed>         Current winds speed
<mmHg>               Pressure in mmHg
<hPa>                Pressure in hPa
<metar>              Raw METAR of the local airport
<atis>               Current ATIS of the local airport
<runways>            The list of active runways
<runways-land>       The list of runways to land on.
<assigned-runway>    The assigned runway (via double click on rwy or e.g. {0.rwy}
<squawk>             The assigned squawk code
<squawk-next>        Assigns a squawk code and replaces this tag with it.
<route>              The assigned route out of flightplan data

Tags with curly braces are arguments. {0} refers to the first one. Example:

.tr 010

010 is the first argument (with index zero, next one would be {1}) .

If the number is followed by a code, the argument is automatically stored in the internal data. For instance:

hs=Hold short runway {0.RWY}

This alias requires one argument, that is stored as 'assigned runway'.

Currently there are the codes:

RWY => assigned runway (example {0.RWY})
ALT => assigned altitude (example {0.ALT})
ROUTE => assigned standard route (STAR/SID) (example {0.ROUTE})

These arguments will be used to maintain future flightplans in the background of your work. There should be no double entry, if possible.
