Shannon Area Control is made up of four high level sectors A, B, C, and D with vertical limits from GND - FL660.
Shannon Area Control has 1 low level sector (EISN Low), with vertical limits from GND - FL245.

FL255 - FL660 — Class C Airspace.
In this part of the Shannon UIR, ATS is provided by Scottish Control (Prestwick) to all aircraft between FL255 and FL660 (Inclusive). Procedures and communications will be as if this airspace were an integral part of the Scottish UIR.
Controllers shall provide Approach and Aerodrome Control to the airfields listed below when the appropriate positions are not online.
Should two overlapping sectors be online at the same time, the lower of the two sectors shall be responsible for provision of Approach and Aerodrome control at the airfields listed below.
A service may be provided to aircraft at airfields not listed below within the lateral confines of a sector. Non-radar units must only be controlled at Approach level only (i.e. APP).

D (SOTA) | Nil |
When high levels of traffic are forecast in a sector (for example during an event). EISN controllers may suspend the top down control at airfields under their responsibility. In such cases, the lowest flight level at which a service can be provided must be notified by ATIS. For more information, please see /a231_policy.
Vertical separation exists when the vertical distance between aircraft is never less than the prescribed minimum. The vertical separation minima are:
Between aircraft flying subsonic:
Between aircraft flying supersonic and between aircraft flying supersonic and aircraft flying subsonic:
Minimum radar separation to be applied is 5nm.
Aircraft on their own navigation where horizontal separation is expected to be less than 15nm and no vertical separation exists should be given radar headings to ensure separation.
Reduced Vertical Separation Minimum (RVSM) permits the application of a 1000ft vertical separation minimum (VSM) between suitably equipped aircraft in the level band FL290-FL410 inclusive, thereby making available six additional usable flight levels.
Track from 180 to 359 (Westbound) | Track from 000 to 179 (Eastbound) |
---|---|
FL430 | FL410 |
FL400 | FL390 |
FL380 | FL370 |
FL360 | FL350 |
FL340 | FL330 |
FL320 | FL310 |
FL300 | FL290 |
FL280 |
The vertical limits of the RVSM airspace are FL290 up to and inclusive FL410.
Note: FL280 is the next usable FL below RVSM airspace. FL430 is the next usable FL above RVSM airspace (2000ft separation).
Aircraft under the control of one sector are not permitted to penetrate the airspace of another sector unless:
Aircraft may enter the airspace of another sector without the need for individual coordination provided that:
Unless specified within the standing agreement, transfer of control will occur at the same time as transfer of communications provided that:
Unless the standing agreement states otherwise:
A sector may transfer traffic that is not covered by a standing agreement without coordination provided that:
