My Husky had a really nice minimal IFR panel. A KX155 Nav/Com, a King
KLN90B (with its own seperate CDI), and a Century I autopilot that was
all electric and worked off the turn and bank. Loose the electric and
you still have the DG and AI. Loose the vacuum and you still have the
autopilot and the turn coordinator AND the GPS (which can work as a DG,
sort of). Top that all off with a handheld radio (with its own antenna)
and a handheld GPS (with it's own permanently mounted outside antennae)
and its pretty damn backed up.
