### Login Priority #### Reykjavik Control (BIRD\_\*\*\_CTR) South 1 (BIRD\_S1\_CTR) may be opened at any time. All other BIRD positions may only be opened after South 1 has been opened (except if South 2 and South 3 are being opened at the same time.) #### Iceland Radio (BICC\_\*\_FSS) Radio 1 (BICC\_1\_FSS) may be opened at any time. All other BICC positions may only be opened after Radio 1 has been opened. See the Iceland Radio page for more information. ## Sectorization [![sector diagram clean.png](https://wiki.vatsim-scandinavia.org/uploads/images/gallery/2023-09/scaled-1680-/sector-diagram-clean.png)](https://wiki.vatsim-scandinavia.org/uploads/images/gallery/2023-09/sector-diagram-clean.png) The Reykjavik CTA is divided into four lateral sectors: North, South, East, and West. ### Bandboxing The South sector positions (S1 / S2 / S3) bandbox the East & West sectors when no controllers are online for those sectors. ### Dynamic Vertical Splits Each sector may be dynamically split up vertically to three times to increase traffic capacity, following these rules: - When two sector splits numbered 1 & 2 are online, they shall split the sector at **FL345** (split 1 is lower, 2 is higher.) - When two sector splits numbered 1 & 3 are online, they shall split the sector at **FL355.** - When two sector splits numbered 2 & 3 are online, they shall split the sector at **FL365**. - When *three* sector splits (1, 2, and 3) are online, sector no. 1 covers **up to FL345**, sector no. 2 from **FL345-FL365,** and sector no. 3 from **FL365+.** #### Bandboxed Splits If there are multiple South sectors online, but no East or West sectors are online, the South positions shall split the South, East, and West sectors at the same level. - For example, if South 1 and South 3 are both online, then they would bandbox the South, East, and West sectors and split them all at FL355. - However, if East 1 were then to come online, they would take over the entire East sector top to bottom, and South 1/South 3 would continue to bandbox the South and West sectors, splitting at FL355. #### Top-Down Whichever Reykjavik Control position covers the lowest vertical levels also covers all local (aerodrome, approach, etc.) positions in that sector top-down. For specific aerodrome top-down coverage for each respective sector, see their individual pages. ## Oceanic Procedures All aircraft in Reykjavik OCA must follow oceanic procedures. **See the [Oceanic Area Control](https://wiki.vatsim-scandinavia.org/books/operating-procedures-wjo/page/oceanic-area-control) SOP for details.**
