Thanks. I understand that on weekends a number of the radar services do not operate - could that be so in the Plymouth area?
Even if they are operating are pilots obligated to use the service or can they operate IFR in Class G airspace without communicating at all ?
I would imagine there would be no en- route charge if not communicating to anyone. Do pilots operate this way to save money?
In Australia all IFR pilots must file a flight plan and be be reporting to the service provider and pay the IFR en route toll at all times- even in very remote airspace.
Sounds as if the UK system could save pilots a lot of money if copied in Australia
