You should note that if you lose lock (too few satellites) then your

which determines if you have a signal error.

Just to clarify, are you saying that a *VFR* GPS's screen flashes when the
GPS loses the required number of satellites for position calculation and
that error is not a result of built-in RAIM?


Portions do such as position. Take your favorite handheld and look
at various displays. Note that some will flash until you get a solid
GPS lock.
