It's generally pretty seamless. They know the fixes and the altitudes,
even though our approaches are obnoxious and contain little or no indication
of how they relate to the enroute system and the IAFs have nothing to
do with airways or intersections on airways or even charted transitions.

Any RNAV IAP developed in the past 3 years, or more, has its IAFs anchored on Victor airways unless
there are no IAFS (I.e., radar required).
