I once worked with helicopters, very large helicopters. The "UI" in the cockpit involved at least 18 gauges measuring all the basic stuff about the engines and associated sub systems. With the helicopter powered down each gauge seemed installed in a random orientation, a couple were even upside down. But when flying the "normal" needle position would point straight up, allowing the pilots to glance quickly to see that all was good without focusing on each individual gauge.
