Mutt, which part of the FAR's are you reading about the critical engine, because certain FAR parts do not apply to jet aircraft.
There is no definition of critical engine on twin jet aircraft as either engine will have the same effect to controllability, in zero wind conditions. Now what is mentioned earlier by others such as Lancer with reference to the x-wind effects are correct but that is just an external effect.
On 4 engine jets we have a speed called Vmcl-2 which is the lowest controllable speed with loss of both engines on the same side which is the worst case senario.
