Nigd3 Thank you. I found both the documents you recommended.
Shawn Your post confirms my understanding for transport aircraft. I am also aware of how Sperry, Bendix and Collins drove early instrument design.
I have not been aware of studies indicating a clear preference for O-I v I-O displays. My personal preference based on testing of both US and Russian equipment would be contrary, though I find both designs functional. I would like to understand the test conditions of studies related to an O-I v I-O preference. I am involved in a new design/test effort for a high workload cockpit. We are attempting to think outside of the box and if a significant improvement in situational awareness and/or reduced workload can be substantiated, or even if a clear preference has been demonstrated in testing, I would like to include O-I in planned testing using both test and operational pilots.
