A correction to my previou post, I believe Oban is to be licenced in time for Summer next year, thats 2007.
Lifes2good, Single Engine IFR for public transport operations will happen in the UK, its a matter of when rather than if. The problem is if it does not happen soon then investment in infrustructure which is happening now and planned for the next year or so may be in vain. Oban, Coll, Skye, perhaps even Barra will depend on the success of SETA.
Your other question about an Instrument Approach Procedure at Oban. The area to the South of the field is relatively clear of high ground, but the overshoot area may be a problem. If this is the case then it will be a 'cloud break' procedure only, that is an Instrument let down which does not align with any landing runway and therefore will have a higher minima to allow for a visual circling segment. This is an acceptable form of instrument approach, but during the winter months will result in more diversions. However, we shall have to wait and see what the approach procedure is after the beacon is installed.
Hope this answers your questions.
If anyone has any useful information about anything happening in the Western Isles/West Highlands, please share.
