Since the SkyView is not a IFR Certified GPS, it is not a legal source of primary navigation when IFR. Thus we do not focus as much on pure IFR features that require a different navigator on board anyway.
Not even the world's most popular certified IFR GPS does victor airways either
I used to file airways, and then request direct as soon as the flight was started. Now I just file direct. I have airways in my GTN 750 driving the Skyview and I have not used them on a single flight so far
