Just to agree with SlyGuy and RW&B. ND operates their 16000 pa movements well despite the aged facilities and sometimes confounding CHC management. This little, undervalued, under resourced airfield could be a gold mine if the top brass in Aberdeen could see beyond the end of ABZ's threshold.
Positives - no opening hours restrictions, no fitting ion with fixed wing, no waiting for fuel, a lot less security hassles for crew and pax, hard working air and groundcrew, shorter flights and free parking!
Negatives - well it looks old and uncared for. It doesn't have an ILS but that is not necessary (see previous posts), it doesn't have a hard runway for the thankfully rare occaisons that it would be needed. Can't think of much else.
