Max talks about common gotchas with RNAV GPS approaches, especially when using vectors to final (VTF). The conversation picks up where Episode 383 left off, with listeners asking how vectors to final (VTF) influences glidepath capture on WAAS approaches.
He explains that under normal circumstances—flying the approach via own navigation from an initial approach fix (IAF)—the GPS glidepath doesn't turn magenta or allow autopilot coupling until the FAF becomes the active waypoint. The magenta color indicates that the GPS receiver has completed a signal quality evaluation, verifying that the WAAS signal is good...
