Airspace Information


The airspace controlled by Iran vACC is separated into 7 sectors. Please use below information to familiarized with our airspace.

General Information


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.

Facility Callsign Radio Freq.
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


Flight Levels


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.
