And tell me that pilots aren't already using those "for situational
awareness only" extended runway centerlines drawn on the moving maps of
VFR-only handhelds to cobble up their own instrument approaches?

.... and tell me that one day some widow is going to sue, and the chance
of her winning is on the heads or tails of a token.

Now, without RAIM the defense "it was VFR only, that was an SPT" holds
more water. With RAIM, the offense is "you built it to appeal to
instrument pilots..." We already have culpability in "appealing to
children", this is not much of a stretch.

And the truth is, RAIM is not useful VFR. It adds complexity to the
software and the screen, to no navigational benefit. But it is
essential IFR (or IMC anyway). So the argument above will gain
traction. Food for lawyers. We pay for it.
