With a solid state gyro you could have your own personal on-board flight
instructor.  I can hear it now...
"PULL UP YOU'RE TOO LOW!  PAY ATTENTION!"
"NO, YOU PULLED UP TOO MUCH, NOW YOU'RE TOO HIGH!"
"YOU'RE TOO SLOW, YOU'RE GOING TO STALL!"
"WATCH FOR TRAFFIC!"
"#&%*#@*&%....

Are we getting creative now or what? :-)>

Paul I think the weight and power requirements for this system as proposed would both be excessive and over budget.
Because even the stereo versions of ANC headsets do not have quadraphonic capability to give correct depth and other spacial cues, the sound would have to come from a loudspeaker, probably a very large one.
To drive such a speaker would require a large power amp.
Amplifiers of this nature, being designed to impress with both bulk and power consumption figures, are not well suited to aircraft use.
For this to be accurate and effective it would be necessary to have the sound come from over the pilot's shoulder and slightly behind, somewhere in the back seat.  :)

Your kidding of course. I have a speaker in my C182. I just bought a Sony
infrared head set for the TV that runs off ONE AA battery for 100 hours.
