It doesn't matter which segment it is for. Unless you have reached safety altitude, you cannot begin to work out climb gradient or what rate of climb is acceptable, you have far more important things to do. So, unless you have reached safety altitude, you should have company information or special 'emergency turn' or engine failure procedures to allow for emergencies. This may be something like 'turn left before 5 miles and proceed to XXX climbing to 2000' and advise ATC'.
