I can understand where the OP is coming from - the fees for using a service that is radiating energy whether anyone is using it or not, are disgraceful.
And clearly you have no idea how much it costs an operator to install and maintain such a facility.
nmp9440a don't be so tight, you may save a few pounds but the guy you delay because of an unknown (you) won't be so pleased (That could be you one day).
And at the non radar units you could potentially pose a far more dangerous threat.
Holding overhead a facility (especially at an airfield with a published hold) without talking to anyone is also poor airmanship in my humble opinion.
The Chevrons on the charts and facilities are there for a good reason.
It's posts like that that can only serve to strengthen the applications for Class D around regional Airports, as another poster suggested earlier.
