I've often wondered if a pendulum, in lieu of a GPS or compass,

I've never tried the experiment.

Here's an easier experiment: take a carpenter's level and duct-tape it
to your bicycle's handlebars. Now, go around a few turns fairly fast
(i.e. the bicycle is at a good bank). Does the level show that the
handlebars are tilted during the turn, or is the bubble still in the
centre?

The answer will help show why you need gyroscopic instruments (or
newer expensive equivalents) to fly in IMC.


All the best,
