What was your first experience of Fly-By-Wire?
In 1990, when I was going through my test pilot training, all the students flew the A320 at Toulouse and the Mirage 2000 at Istres.
The principles of flight are the same for all aircraft, however with Fly-By-Wire the sidestick measures the force applied and translates that into a command. The Flight Control Computers then calculate the appropriate control surface movements to provide the desired aircraft response.
Later in the 90s, I worked on Fly-By-Wire military fighters. That’s a different experience as, unlike commercial aircraft, without the computers they would be very unstable and for some, impossible to fly.
