I quite agree, although procedural based ATC is slow, it is quite fast enough for the facilities at Inverness. It is simplistic to say that if they had radar they would be able to handle more ac; this is simply not true. The concrete limitations at the airport would see to that. The question of radar increasing safety is also a good point to make, but as long as airlines are happy with what they get there will be no impedious for change.
As one Hollywood film stated, "if you build it, they will come". Well they haven't built it so stop bloddy comming.
