I was just reading an article reprinted from the FAA Aviation News publication (which I didn't know existed). The article, from the March/April 2007 edition and titled "The Future is Now and You'd Better Catch Up", states:
"We often forget that GPS is not approved as a primary method of navigation."
It goes on to reference an article in the Nov/Dec edition which does not say anything about GPS not being "primary". It, and the AIM (1-1-19(d)(1)(b), talk about having an alternate means of navigation in case RAIM is lost but nothing about "primary" that I could find.
So here's the question: Is this a significant difference? If so, which is correct?
Thanks,
Sam
