Sligo is purely operational as a helicopter base and will never see revenue service again
You really need to start checking your facts, Sligo has an active GA base, regularly used by the Air Corps PC9s, in the last few weeks has seen regular business traffic (Citations, PC12s, Islanders)...
In the case of both Sligo and Waterford, for performance reasons the S92 arrives and departs on the active runway and its rare to operate straight to the pad.
