I am aware of the supplement, my POH says that my equipment is only B-RNAV approved (thus to my understanding only the en-route phase) hence question #2, at what point can i start using my GPS and where do i have to revert to conventional navigation?
A G1000 or GNS430 (is yours a 430 or a 430W?) can be RNP1 approved
generally, so from the DP/SID, En-route, Arrival, Initial, Intermediate and Missed approach. Crew approvals for certain RNP is another issue.
See page 6

The POH or supplement is more likely to say RNP capabilities, not "can/can't be used for..."
If yours states B-RNAV
only then it is B-RNAV only. I'd have thought you can use it from the word go, but backing up by
identing and
displaying conventional navaids.
Please don't take my advice - ensure what approval you have with your particular fit. Which type of aircraft and what specific kit is installed and approved?
