RADIAL SIDS with GPS

Fly IFR in busy airspace and eventually youll have one of those much ado about nothing experiences. It starts with a clearance you dutifully put in your navigator-and then repeatedly change or completely ignore until you get a clearance to resume the plan you were given at the start.

Key Takeaways:

  • IFR flights often involve frequent Air Traffic Control (ATC) vectors and altitude changes, leading to deviations from initially filed and loaded departure procedures.
  • Modern GPS/RNAV systems load detailed procedures, including RNAV-specific fixes, but don't automatically adapt when ATC vectors pilots off a published departure.
  • Pilots must understand their navigation system's behavior when interrupted by ATC, knowing how to manually activate a new leg or direct the system to follow current instructions rather than trying to fly bypassed waypoints.
