Use of VRPs by ATC
Just seeing that Waltham thread reminded me of something...
Something which has come up a number of times on VFR trips over the years is that ATC sometimes use VRPs which are unpublished.
AIUI, they should use only VRPs which are in the AIP. Those VRPs will then find their way into VFR charts (national, Jepp, etc) and into GPS databases.
But the local ones won't be known other than to locals.
I am suprised as to the extent to which this goes on.
Perhaps ATC are aware of this, and use the local ones only for pilots they know will know about them? A non-local or foreign pilot is going to get a bit of a "cockpit workload increase" otherwise...
