I have heard recently that due to the extensive usage of GPS in Southern Alberta, fewer pilots are filing flight plans in the area. Coupled with cutbacks at NavCanada, it is rumoured that certain stations may be shut down in the near future, including Springbank and possibly Medicine Hat. While this is inconvenient for many pilots, the increasing versatility of GPS and the use of the internet to obtain weather has resulted in fewer direct services being used by pilots. Any feedback would be appreciated.
