Aircraft labels are defined separately from the colours and symbols used by labels & tracks. The contents and layout of the label may be customised.
Every FIR can specify an unlimited number of label formats. Label formats are defined by the label directory name located in fir/labels/(label_name).xml
A number of different aircraft states exist, all of which can have a distinct label format:
Airborne labels
The default label must be defined as a minimum. All further states are optional and only need to be defined if the label layout for the state differs from the default state. Note that the colours of a track/label state completely are independent.
Ground label
The default label must be defined as a minimum. Further states are optional and follow the logic of the airborne labels.
A huge variety of usable fields exist which can be customised to suit the desired visual presentation.
Fields are configured with a number of variables:
| Field | Function |
|---|---|
| tag | text to show when the field is empty |
| unselected | show the field when label is not selected |
| prefix | character ahead of field |
| format | field format in formatter type (see below) |
| units | unit types see below |
| action | single click on the field |
| doubleaction | double click on the field |
| info | second (right) click on the field |
Formatters
| Field | Function |
|---|---|
| default format for field | |
| F | for altitude fields places F in front of the altitude if field is FL (F for feet or M for meter) can only be combined with %02d, %03d |
| A | for altitude fields places A in front of the altitude if field is below TL/TA can only be combined with %02d, %03d |
| AF | will place a F/M/A in front of the altitude depending on it's type can only be combined with %02d, %03d |
| %02d | formats a field to show 2 numbers (drops last) or pads left if < 2 numbers exist |
| %03d | formats a field to show 3 numbers (drops last) or pads left if < 3 numbers exist |
| %04d | formats a field to show 4 numbers (drops last) or pads left if < 3 numbers exist |
| %4s | formats a character field to take up 4 characters. number can be any numeric value |
