General
Real Irish airspace contains a lot of different ATC positions. On IVAO we normally do not have to deal with large amounts of traffic, therefore some positions will only be available on special occasions. Other positions are not used on IVAO at all.
Although we try to keep things as real as possible, sometimes it is not necessary or practical to implement complete procedures, in such an event, the procedures will have been adjusted to meet our specific virtual needs.
Available Facilities
Positions with N/A behind them are only to be used during events and are utilized on discretion by the ATC Operations Department.

(*1) Excluding the class G airspace within Dublin CTA. (More info)
(*2) The aircraft needs to be able to reach the IAF at FL60, therefore if it is clear for Dublin Control that the A/C does not need to make a holding, he should handover the A/C as soon as possible to Dublin Director. This would be atleast 10NM before reaching the IAF.
All other airports within Shannon FIR is class G airspace, and therefore have no controller.
Definitions
Shannon FIR
All Irish airspace from surface to unlimited.
Shannon UIR
Lateral limits as for Shannon FIR, including NOTA and SOTA.
Class C: from FL245 up to Unlimited
NOTA and SOTA
Class A: from FL55 up to Unlimited
Shannon CTA
Lateral limits as for Shannon FIR, excluding Dublin CTA and all control zones.
Class C: from FL75 up to FL245
The areas just outside the control zones have different altitudes, check the approach charts for each airport for more details on this.
Dublin CTA
Dublin airspace upto FL245.
Tasks
Shannon Control (EISN_CTR)
Shannon Control sequences over flying traffic in the Shannon FIR, on high altitude airways.
Shannon Control (EISN_L_CTR)
Shannon Control sequences traffic to and from Irish airports except the airports residing in Dublin CTA.
Shannon Control takes care of all departing traffics within Shannon CTA, except at Cork and Shannon airport.
Shannon Information (EISN_I_CTR)
Shannon Information provides traffic and weather information to pilots flying in class G airspace, on pilots request.
This position should not be used, unless it is appointed to you by the ATC Operations Department.
Dublin Control (EIDW_N_CTR)
Dublin Control sequences traffic within class C airspace, to and from airports within Dublin CTA.
Dublin Control also handles departing traffic from airports within Dublin CTA.
Dublin Control (EIDW_S_CTR)
Dublin Control sequences traffic within class C airspace, to and from airports within Dublin CTA.
Dublin Control also handles departing traffic from airports within Dublin CTA.
This position should not be used, unless it is appointed to you by the ATC Operations Department.
Dublin Director (EIDW_APP)
Dublin Director handles all arrivals for Dublin, Baldonnel and Weston. Baldonnel however can have its own Approach Controller.
Task Delegation
When a controller is online, he always inherits all area's which are "below" his current position.
Some examples:
EISN_CTR inherits all tasks from all facilities in Irish airspace.
EISN_L_CTR inherits all tasks from all facilities except the tasks done by EISN_CTR.
An Approach controller normally only handles arrivals. When an area controller is not available, the approach controller also handles departing traffic.
An Approach controller also takes care of Tower, Ground and Delivery tasks if they are not online.
Dublin CTA
Dublin CTA is a big area. It has it's own area control centre (ACC). This area control centre operates up to FL245, and consists of 2 area's. North and South, devided by the centre line of runway 10/28.
On IVAO we normally do not use South Control, this means that North Control takes both areas.
Agreement between Shannon Control, Dublin Control and Dublin Approach
When EISN_CTR and EIDW_APP are both online, EISN_CTR will do tasks for EIDW_N_CTR, as EISN_CTR is the higher position. When EISN_CTR and EIDW_N_CTR are not online, EIDW_APP is allowed to do the tasks of EIDW_N_CTR.
When required, for example when EISN_CTR is very busy, EIDW_APP can also do the tasks from EIDW_N_CTR, this needs to be coordinated first between the two positions. If EIDW_N_CTR comes online at this point, the default setup will apply.
