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 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">

The sector is defined by one of more volumes of airspace. Each volume is a polygon with a upper and lower level. A sector must have at least one polygon.

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.
