I’ve seen this before but haven’t really asked the question to get an answer.
So if you fly IFR and your plane only has a gps navigator and your intended airport requires you to file and alternate it states in the regs that you can’t plan to fly a gps approach at both places.
Online explanation states, “ that means with GPS only you can only fly RNAV approaches and you can’t plan IFR flights that require an alternate”.
So does the above statement mean if your intended destination requires you to file an alternate airport you can't file IFR? So if you only have a GPS navigator you can only fly IFR if an alternate airport is NOT required. Is that correct? Does it still apply if you have a Waas gps navigator?
Here is Advisory Circular, AC No 90-105A, dated 3/17/16.

I’m not sure what it means but does it allow you to fly gps approaches at both locations if you have a waas gps?

9.5.1.2 Pilots with WAAS receivers, TSO-C145( ) or TSO-C146( ), may flight plan to use any IAP authorized for use with their WAAS avionics as the planned approach at a required alternate, with the following restrictions. When using WAAS at an alternate airport, flight planning must be based on flying the RNAV (GPS) LNAV or circling minima line, or minima on a GPS approach procedure, or conventional approach procedure with “or GPS” in the title. Properly trained and approved, as required, TSO-C145( ) and TSO-C146( ) equipped users (WAAS users) with and using approved baro-VNAV equipment may plan for LNAV/VNAV DA at an alternate airport. Specifically authorized WAAS users with and using approved baro-VNAV equipment may also plan for RNP 0.3 DA at the alternate airport as long as the pilot has verified RNP availability through an approved prediction program. Code of Federal Regulation (CFR) Part 91 nonprecision weather requirements must be used for planning. Upon arrival at an alternate, when the WAAS navigation system indicates that LNAV/VNAV or localizer performance with vertical guidance (LPV) service is available, then vertical guidance may be used to complete the approach using the displayed level of service.
