Depends a bit what you mean by partial panel - normally you have one source for AI and a different one for turn indicator. Failure of one system thus leaves you with a decent roll indication and should be no great problem for someone trained and current, as I say, many find it easier as you have less of a scan to do and in training you often find student fly better on limited panel than full because of it. Single source, as can happen on home built scan mean you lose ALL basic roll indications, that
really makes life difficult, and I would not fancy that in real life!
