I think it's a little unfair to compare RHADS and HUY. Humberside have applied for the establishment of a small amount of CAS to mitigate what they have percieved as a steady increase in risk to their traffic in recent years. Ahead of publishing the consultation document they have visited numerous airfields in the region to explain their reasons for the application. In terms of size there really is no comparison between the 2, HUY have gone for protection, RHADS went for full connectivity.
