The airspace controlled by Iran vACC is separated into 7 sectors. Please use below information to familiarized with our airspace.
In real life and due to the volume of traffics, Tehran FIR is covered by 7 main radar positions and 15 subzones. However, we on VATSIM rarely have the need for staffing all these radar positions or the subzones. That is why, when an ATC CTR controller is online, he/she will connect as Tehran Radar (135.200 MHz) and control the entire Tehran FIR. Also, this controller is in charge for any other position inside the FIR when those positions are offline. You can learn more about this below.
|Tehran Radar (General)||TEH_CTR||135.200 MHz|
|Tehran Radar Sector 1||TEH_1_CTR||119.300 MHz|
|Tehran Radar Sector 2||TEH_2_CTR||125.700 MHz|
|Tehran Radar Sector 3||TEH_3_CTR||126.900 MHz|
|Tehran Radar Sector 4||TEH_4_CTR||133.400 MHz|
|Tehran Radar Sector 5||TEH_5_CTR||120.300 MHz|
|Tehran Radar Sector 6||TEH_6_CTR||123.900 MHz|
|Tehran Radar Sector 7||TEH_7_CTR||120.700 MHz|
Pilots maintain a specified flight level during the flight. The rules are simple – if the flight is westbound, altitude should be even and if it is eastbound, it should be odd. In Iran, we use Reduced Vertical Separation Minimums this means that the difference between opposite-directional routes will be 1000 ft. Below image is visualizing the principle of vertical separation.
