Imagine you're planning a VFR trip. You call AFSS (800-WX-BRIEF) for a briefing, stumble through the computerized voice selections that can't understand that Iowa is not Ohio, and finally connect with a human briefer who says, "VFR not recommended." (VNR) Dang! VFR not recommended means:


You are not permitted to fly VFR.


You must file and fly IFR.


Conditions make flight under visual flight rules doubtful.


Winds are forecast to exceed 55 knots at the surface.
