Is it possible to switch from VFR to IFR and back?

ok

Also, here's the Pilot's Handbook of Aeronautical Knowledge:

I had downloaded the PDFs of the FAA's books before I went out and bought
the print versions. Why, some of you may ask, would I pay good money for
something I already had free electronic copies? Because it's tough to haul
my desktop (or even laptop) computer into the (ahem) bathroom, or to the
easy chair in the living room, or prop on my chest while lying in bed.
