To use the equipment suffix "G", does the GPS have to be certified for IFR flight?

    $\begingroup$ What equipment suffix are you referring to? $\endgroup$ – selectstriker2 Apr 5 '19 at 17:17

  • $\begingroup$ @selectstriker2 /G is the equipment suffix used in FAA IFR flight plans for GNSS plus mode C $\endgroup$ – Pondlife Apr 5 '19 at 18:17
  • $\begingroup$ In the US if you are just getting flight following, you can use the /G suffix when making your request to ATC. However, in 20 years of using flight following on almost every flight, I have never had ATC give me anything but a heading to follow so it really doesn’t matter what you use. $\endgroup$ – JScarry Apr 5 '19 at 19:14
  • $\begingroup$ @JScarry That's interesting, why do you include equipment details in a fight following request? $\endgroup$ – Pondlife Apr 5 '19 at 19:30

Yes, using GPS for IFR requires a certified unit. The AIM 1-1-17(b)(2) says (emphasis mine):

Authorization to conduct any GPS operation under IFR requires:

(1) GPS navigation equipment used for IFR operations must be approved in accordance with the requirements specified in Technical Standard Order (TSO) TSO-C129(), TSO-C196(), TSO-C145(), or TSO-C146(), and the installation must be done in accordance with Advisory Circular AC 20-138, Airworthiness Approval of Positioning and Navigation Systems. Equipment approved in accordance with TSO-C115a does not meet the requirements of TSO-C129. Visual flight rules (VFR) and hand-held GPS systems are not authorized for IFR navigation, instrument approaches, or as a principal instrument flight reference.
