Q: When are intersections used in FSX? Are intersections an alternative approach in the real world? Is there a benefit to intersecting the IF over an intersection?
Is there a way to include 2 transitions both originating from MRB but one through the intersection at BEEZY and the other through the IF at LAUGH?
We normally add a T_Waypoint at every intersection. This is so a line will be drawn on the GPS receiver from MRB to BEEZY to LAUGH as a Transition. FSX uses Waypoints for all intersections if you open the map mode and take a look.
You cannot have 2 Transitions from a single NAVAID such as a VOR, NDB or Waypoint. When you request a Transition from ATC it will tell you cleared direct to MRB and that transition must go through BEEZY amd then to LAUGH. If you had 2 Transitions from MRB then ATC would get confused on which one you were requesting (MRB to BEEZY or MRB to LAUGH)
We can play a trick on FSX and add a T_WAYPOINT on top of the MRB VOR and name it MRB1. Now that named Transition would be MRB1 and could then go direct LAUGH and ATC understands you intentions.
