"feel" is a very important word here. Feelings can be tactile, aural,
visual etc etc.

Can anyone categorically state that on Airbus's 320, there is absolutely
no feedback at all to tell the co-pilot (or pilot) that his joystick is
not the active one ?

Has anyone though that perhaps there might be a buzzer, or perhaps a big
flash on the CRT or some other method to warn the pilot ?

As well, perhaps the Airbus engineers decided that it was impossible to
provide the complete feel to an electronic joystick and that another method
would be best to give the pilot the feedback that is required.

In other words, they may have decided that it would not be safe to give
the pilot a false sense of feedback through the joystick when that sense
could not represent all that was going on.
