Thank you for your reply, but I just can’t imagine the crew dealing with a start problem with the N3 above 50% by ECAM actions. In my mind, a problem in these circumstances (high N3 rotation) would require a fast manual start abort to preserve the engine. Nevertheless, it makes sense and probably was the best way of dealing with these kind of start problems that Airbus considered.
If anyone has ever had a problem like this, it’d be really helpful to illustrate this scenario.
