Unfortunately, this is more of a user education issue. And I don’t mean that at all in a mean way, everyone has different knowledge levels and that’s totally OK! However, what our NXi is showing is 100% real world unit correct for this specific case: a flight plan with YPAD as the origin, YPED as the destination, with ILS Z 18 selection and no selected transition.
Here’s the real unit:
And here’s ours:
As you can see, they’re matching perfectly (except for the change in the FAF name, slightly different navdata). The reason you’re seeing a discontinuity in your plan is because you have not selected a transition for the approach, and thus this is a Vectors-To-Final, which requires the pilot to make their way to the final approach course on their own before activating the approach.
If you would like to have a more conventional approach, you would need to select a transition in the approach, which would then make it look like this:
Of course, because the flight path you’ve chosen has a super acute angle turn, our unit, just like the real one, will insert a course reversal for you.
Hopefully that helps!
