Thresholds of acceleration sensitivities for the standard man/woman pilot.
Maybe worth getting in touch with Prof Griffin (
http://www.isvr.soton.ac.uk/STAFF/staff17.htm) at the Institute of Sound and Vibration (ISVR) at Southampton university (
www.isvr.soton.ac.uk). This is exactly the kind of thing they get up to, and I'd guess they'd be interested in a project applying it to aviation. Plenty of phd oppertunities available in that department for later on
Good luck,
MrS
