It doesn't matter, you go by the chart.

So you need a chart, which means that a compass alone isn't much use.

If you want to go to and from true and magnetic, you need a chart to
get the local difference.

If you want to go somewhere in particular, you need a chart to find it.

If all you want to do is go in some particular direction until you
can see a recognizable landmark, all you need is a compass.

It is called a chart. If you have a chart and a compass, you are
all set.

You need to know the heading to use to get somewhere. You use the
compass to actually go that direction.

You mean like fly a heading 230 degrees for 47 miles and there will be
a lake. At the lake fly a heading of 273 degrees for 32 miles and
at that airport, fly a heading of 264 degrees for another 44 miles
and you will be at your destination?

You obviously know nothing of real world navigation.

You don't know what that heading is unless you already know where you are.

How do you know about the lake, with only a compass as your guide?

No, it's just that I know about covert channels.

If you have a heading to get to where you want to go, the details of
your current position are irrelevant.

If the bathroom is down the hallway to the left, does it matter where
you are in getting to the bathroom?

Don't be an even bigger idiot than you already are.

Given the task is to get from point A to point B and you have a compass,
the only information you need is the heading from point A to point B.

No, the compass doesn't tell you what it it supposed to be, you need
something else to tell you that, whether it is another person, a
chart, or you just happen to know it.

So, you need a heading and a compass to follow that heading.

Do you wrap your head with foil when you don't want to receive those
channels?

You cannot calculate a heading for where you want to go unless you already
know where you are. The only places you can go with a compass without already
knowing where you are are the north and south magnetic poles.

Don't be an even bigger idiot than you already are.

I'm simply pointing out the errors in your argument. You cannot know where
the lake is without a chart; a compass will not tell you about lakes. And if
you have a chart, you are not navigating with a compass alone.

Given the task is to get from point A to point B and you have a compass,
the only information you need is the heading from point A to point B.

You can only calculate that heading by knowing the positions of points A and
B, which means you cannot do it with just a compass, unless point B is one of
the magnetic poles.

No, the compass doesn't tell you what it it supposed to be, you need
something else to tell you that, whether it is another person, a
chart, or you just happen to know it.

So a compass alone does not suffice. QED.

Yeah, eyes. Lots of people flew across the Atlantic with sometimes
just a compass, and they easily recognized the coast of England /
France / whatever with their bare old eyes ;-)

Heck, you don't need a chart with you to recognize the Eiffel Tower,
for example.

How would I know if I was in France or Virginia?
