They do have an aviation specific gadget that does what you want. Check out APPAREO at appareo.com and look at the VISION 1000. I worked for a 135 outfit about 15 years ago and they tried out the original version of this device. It was a "strap down" gadget and recorded pitch, roll, heading etc and had a dedicated WAAS GPS. It could be easily moved from aircraft to aircraft. It was used for flight data monitoring. Plain english, it was/is a "snitch." Price tag alert: 15 years ago it ran about $5,000.
