Well, I guess that's a bit like people who might easily misinterpret your post as being known fact, when actually it was something else?
p.s
All I can say is do yourself a favour and make yourselves as familiar as you can with the AIP book, in particular (in .PDF format, R click and 'save as')
AIP Enroute (ENR),
Sections ENR 1.2 Visual Flight Rules, ENR 1.3 Instrument Flight Rules, ENR 1.4 ATS Airspace Classification, ENR 1.7 Altimeter Setting Procedures, ENR 1.14 Air Traffic Incidents,
and,
AIP General (GEN) <-- as much as you can.
