It turns out that humans are faster at reading analog gauges vs digital. The exception being a clock because actual math is involved (multiply what the long hand says by 5). That's why even in today's digital cockpits, graphical displays of analog gauges are still used vs a simple number.jfoster33702:To that, I would say, "How many divers have died from mis-reading analog gauges, or making a mathematical mistake in their dive planning?".
As far as a mathematical mistake (e.g. how much air do I (and my buddy) need to get to the surface), I am sure that's a common problem but I don't think the solution is to replace the brain with a computer - the solution is to upgrade the brain. As I pointed out in another thread, the readout of mins remaining before you must begin your ascent on most AI computers *DOES NOT* include what your buddy would need should he rupture an LP hose or blow an o-ring. I fear that these computers tend to make us stop thinking about real dive planning and we end up just relying on what the computer tells us without thinking of scenarios like the one I just mentioned.
