IvAc 2 sector system

The sector system in IvAc 2 will implement the following major changes:

• 3D definition of each sector, for traffic detection and WebEye display.
• The ability to combine and split sectors without reconnecting or changing frequency
• The ability to activate and deactivate sectors individually

A position is an individual controller connected to IVAO. Theoretically a position will be able to activate a number of sectors simultaneously which will be individually visible online.

A sector is an indivisible block of airspace which may be activated. Each sector is composed of the following:

• Sector ID
• Sector Name
• Radio Callsign
• Frequency
• Type (DEL, GND, TWR, APP, ACC, FSS)

<sector id="Y" name="Yellow sector" callsign="Somewhere Radar" freq="125.550" type="acc">
<volume id="Y_Sect_1" />
<volume id="Y_Sect_2" />
</sector>

The sector is defined by one of more volumes of airspace.

A volume is a polygon with a upper and lower level that defines the airspace of a particular sector. A sector with 2 different upper/lower levels such as Y sector would have two volumes.

Volumes of separate sectors may overlap and the smallest volume will be considered. Reference to the diagram above, in Y sector there is no need to cut out the APP airspace.

Note that DEL, GND, TWR sectors don't have volumes as they are linked to the aerodrome reference point & transfer conditions are different than between airborne sectors.

<volume id="Y_sect_1" top="999" bottom="000">
<point lat="N0494918000" lon="E0041835000" />
<point lat="N0494918000" lon="E0041835000" />
<point lat="N0494918000" lon="E0041835000" />
</volume>
