It's not gray. You are on a vector.


You are on a vector when and only when you're instructed to fly a specific
heading or when instructed to turn a specific number of degrees in a
specific direction.



Right, ATC doesn't get into enforcement. You can very easily, and much
more accurately, fly an NDB approach with a handheld GPS. But it ain't
legal. Same with direct using a handheld. Your beef will be with FSDO.


There's nothing illegal in the use of a handheld GPS for IFR enroute flight
in US controlled airspace.
