Supplemental technology additions to cars has greatly enhanced the safety of driving on our highways. But, 30,000+ folks still die on our highways.
Airbags, antilock brakes, stronger door beams, etc. have all allowed folks to walk away from a crash.
The technology Airhart is developing is a major change in the way of controlling an aircraft, not additive technology, like our GPS nav capability, autopilots that can follow a gps course.
Fly-by-wire is a requirement on commercial airliners weighing 500,000 lb, where human effort cannot move the control surfaces without hydraulic assist.
But applying this to light GA aircraft is an unnecessary complication of the control systems, and reduces the reliability of them.
