I'm not too sure about the first two -- if relative wind told you
anything at all about whether the wings were level, we be able to use
something simpler than gyroscopic instruments for IFR today. It you
take the last two, ball and altimeter, and add the magnetic compass,
then it would be at least theoretically possible to fly straight
(-ish) and level (-ish) in IMC, though they probably just flew very
close to the ground, as Durden's article suggested.


All the best,
