Setting altimeters with no radio

Found it, thanks. I'm surprised that just setting it at the airport
would suffice--one could conceivably fly for hundreds of miles VFR,
and the altimeter could change significantly along the way.

That Reg does not apply to flight within 3,000 above the surface.
You have to look at two other Regs to conclude that.
Therefore, under 3,000, an adjustable altimeter is not required
per 91.205. FARs don't apply to you; stay away.

The requirement stated in 91.121a1iii does not include any exception for
flights under 3000' AGL. If you have an adjustable altimeter, you have to
set it according to 91.121, regardless of your altitude.

Therefore, under 3,000, an adjustable altimeter is not required per
91.205.

According to 91.205, an adjustable altimeter is only required for IFR
(regardless of altitude).

An altimeter adjustable for barometric pressure is not required for VFR
flight at any altitude.

If you're operating at any altitude below 18,000 feet and you're equipped
with a radio and you have an altimeter adjustable for barometric pressure
you must set it to the current reported altimeter setting of an appropriate
available station, VFR and IFR.

But it would be kind of weird to be above 10K where a Mode-C transponder is
required, but not have a radio or altimeter...

VFR, it doesn't really matter, does it?

Not below 3000 AGL, it does above that.

You seem to be suggesting that when flying VFR above 3000', we have an
obligation to fly specific altitudes within some tolerence and, therefore,
need to have an accurate means of determining our altitude. That is
certainly not the case. Prudent, yes. Required, no.

I've always thought that airspace boundaries are to be respected by VFR
traffic, too.

I agree that there are many reasons why I need to know my pressure
compensated altitude to avoid busting airspace or illegally flying to close
to person or property.

The discussion was about the life-saving necessity of an accurate altitude
instrument. MX was claiming that GPS is inaccurate enough to kill you. I
presume that that can only happen in one of two ways 1) I fly into the
ground believing my inaccurate intrument or 2) I fly at an altitude
different than the regulated VFR cruise altitudes and run into another
plane.

I think both are highly unlikely in VFR conditions no matter how inaccurate
the instrument.

My filter failed and this message popped up... Not an issue of any
importance in itself and fixed again with two mouse clicks...
However, seeing the list of you tripping over yourselves to answer his
trolling have me howling with laughter...

Since it is possible to fly without voice radio equipment, and given
that (if I understand correctly) pilots are supposed to have their
altimeters set correctly to a reference located not more than 100
miles from their position, how does an aircraft without a radio keep
its altimeter properly set as it travels?
