Why is it that the compass on my iPhone can give true north, but the airplanes cannot do this?

Because your iPhone is a computer, it has a GPS, and it does the calculation for you.

A well equipped aircraft can do the same thing, if the pilot wants it to.

Still, a simple compass doesn't break easily, and doesn't require electricity.

KISS.

Learn it. Live it. Love it.
