You need to remember that we all take the realism of FSX to whichever level we choose. So if we choose to use the GPS, real or not, we choose to use it. I choose to use it if I want to.

One point I was trying to make is that the term "use the GPS" would in fact suggest unrealistic navigation in the 732, but using this particular switch does not add GPS capability to the airctaft. Merely allowing FS to following the flightpath is not GPS navigation. There is no Global Positioning SYSTEM in use, it's nothing more than FS keeping the aircraft on path. It could actually be called "rail mode".

If someone actually flies this way, of course it's unrealistic. And frankly, it would be unrealistic even if you had a GPS installed. There's much more to GPS navigation than simply not using radio NAV.

But to switch to this mode so you can go make a cup of coffee or whatever, hardly makes your simming any less realistic than pausing the sim or even using 2x, 4x, etc. It's really more of a FS feature than an aircraft feature.
