I remember when such a system was being tested at the National Research Council at Ottawa in the early 1980s.
It was being tested on a modified Bell 205.
I do vaguely recall that the tech was being developed in conjunction with Sikorsky. The rear cabin contained a huge computer.
The pilots liked it.
I know not what happened to the program.
The 205 was NRC’s flying test bed for a lot of projects and had no stab bar.
Great bunch of folks.
