HeliPilot didn't come along until much later.
John, I did my conversion in November '80 and we had the Helipilot fit, think we may have been the first customer.
A question to those who may know, with the A model you had the ability to couple with only one system operational. The C model and 412 needed both systems operational to be able to couple. Certification change or what? Certainly made life more difficult.
