Autobrakes on landing should be optional.Let the pilot decide.RTO is a different matter.However,I would say that until the pilot has learned to use manual braking as smoothly and evenly as autobrakes,he/she should be discouraged from using autobrakes.Avoids automation reliance.Some FO's when asked say theyve never touched the brakes in anger which is not right.Get comfortable with manual and then use auto at your discretion(short rwys x-wind etc).An airline that makes AB usage mandatory is not correct.
