And that tells you your course, not which direction the nose is pointed.

For navigation, your ground track is more important.

There is no GPS instrument available that will tell you which way
your nose is pointed.

As I've said, you just use two.

There is are GPS instruments available that can be linked to tell you
that.

The only two places on Earth a magnetic compass doesn't work in an
airplane are over the north and south magnetic poles.

No. There are thousands of local magnetic anomalies that can make a compass
useless.

Not at airplane altitudes and speeds.

If there are thousands, name just 30.

Piston engines have magnetos which generate the spark plug firing
voltage, and only the spark plug voltage.

Last time I checked, sparks counted as electricity.

Well, I can see electricity can be added to that ever growing list
of things about which you know nothing.

Magnetos generate pulses measured in the thousand of volts and microamps
of current. Even if they were hooked to something else, which they
aren't, the power generated would be useless for powering something like
a GPS.

My god, everytime you say something, more ignorance just roles out.

Then why are they marked on the charts?

Are you saying that sparks are something other than electricity? What are
they, then?

Volts? Microamps? These units are used in electrical engineering, not
plumbing.

Even if they were hooked to something else, which they
aren't, the power generated would be useless for powering something like
a GPS.

But that wasn't the assertion. The assertion was that there was no
electricity in some aircraft. If they have typical powerplants, there is
electricity.

My god, everytime you say something, more ignorance just roles out.

I'm not the one making the mistakes.
