The navaids at CAX are an NDB and a DME. There are NDB(L)/DME procedures published for both ends, with OCHs for a Cat B aircraft ( I believe the ATRs fall in this category) of 500ft on 07 and 407ft on 25.
I don't know what is planned but I guess they would want an ILS at one end at least in order to lower the landing minima to improve schedule regularity once (if) airline services commence.
I would think they also would need to improve the approach lighting in order to get decent Cat 1 ILS minima. Runway centre line lights would improve take off minima and these could be incorporated when the runway is rebuilt. All a question I suppose of how much Stobart are prepared to spend on a loss making operation of which the primary function is to get them their distribution centre.
