Now I'm confused
Would you mind explaining BRNAV a bit more?
The reason for my question was because of a situation that arose a few days ago. I work in an FBO, and one of our customers had to have their FMS removed from a C525. They wanted to know if they could FPL back to their base in spain without being RNAV equipped. I didn't think it would be a problem provided they remain below RVSM airspace, but I guess it's probably more complicated?
