Handheld GPS adaptible to aviation

Clearly navigation requires some information. When walking
or drifting with the ocean currents, a map is not needed.
Lewis and Clark made maps as they walked westward.

But today, without a current chart, in the cockpit, you will
violate some type of airspace in short order. Yes, many
things can be left out, you don't NEED a compass if you can
see the sun or moon or the North Star. Maybe you "know" the
river and will follow it [MSP to STL, for example] but
navigation requires the navigator to have information.
Merely blundering around in the air can be done by anyone.
