during IFR operations they may be considered only an aid to situational

You fly a heading with your DG, not your GPS. If you want to proceed direct
somewhere with your handheld GPS then just ask for direct.

and in the case of lost comms, do you just dead reckon? Do you base
your life off of something completely untested? Note, all of this
I assume your talking about flying to a point 300 nm away where
all nav systems (other than IRU's, VOR-DME FMS, etc. that large
aircraft have) do not work at such long distance.
