Followup: there's also AIM 1-1-19 (d)(1)(a): "... VFR and handheld GPS
systems are not authorized for IFR navigation ... [under IFR] they may
be considered only an aid to situational awareness."

The AIM is not regulatory, but could reasonably be brought to bear when
determining the meaning of the word "appropriate" in FAR 91.205(d)(2).

I note in passing that the AIM 1-1-19(b)(3) has an extensive discussion
of the risks of relying on a VFR GPS in IMC.

and note that the AIM has been updated a few times with the intent of
clarifying the use of handheld GPS for IFR operations. IOW - the FAA has
had many chances to "correct" the AIM.
