That's incorrect. Most users filing IFR would have an expectation that the plan was addressed very differently to VFR plans, specifically being sent to CFMU for approval. So the issue is a lot more complicated than you imagine. If it really were that simple then we would of course do it - but when we do things, we try to do them right (or not at all).

Hi

I asked this before, but never got an answer. Why won't SD allow the pilot to file an IFR or combined IFR/VFR flight plan?

I know it's not an IFR product and it doesn't generate IFR routes, but I can create the routes myself using other tools and I would really like to be able to use SD for filing any of my flight plan no matter if they are V, I, Y or Z.

It only takes that you open up one field and allow the user to chose between the four letters.
