Hi, I am a retired mechanical Engineer based in Galway, Ireland. Held a PPL since late seventies. With the advent of TAA "glass cockpit" aircraft, is pilot spatial disorientation still the insidious killer? Around fifteen years ago, I designed and reduced to practice a device that could prevent a pilot becoming disorientated in IMC, or help him/her regain control during disorientation. I didn't pursue the development of the device as I presumed the avionics technology advancement at the time would resolve the problem. What I am really asking is, has SD ever been successfully solved? Thanks, joe
