Dick,
I’m amazed that the air traffic controllers would allow this. Having a mandatory requirement for VFR aircraft to monitor ATC frequencies means that in a radar environment the air traffic controller has a duty of care to the VFR aircraft – i.e. the controller must call the aircraft if it is getting close to another aircraft and give traffic information.
I'm amazed that you think the concept of a person on a radar advising one or two aircraft that they may be getting close to running into each other is amazing.
If the VFR aircraft hears an IFR aircraft in the vicinity, the VFR aircraft must make an announcement.
Wrong again. Back to the books for you, sonny.
