Approach Climb
Could anyone please give me the history/reason why the min approach climb gradient(twin)required is 2.1% for an instrument appraoch down to cat 1 min (200 or above) and yet the PANS-OPS missed approach segment, climb gradient required/clearence is based on a 2.5% gradient.
Also, please correct me if I am wrong, is it not the operator's responsability to ensure that the a/c will achieve, at it's planned landing weight/forcast temp's, the 2.5% even though the min required 2.1% could be achieved?
Many thanks
