Aslan1982;
At the risk of appearing pedantic, I think two minor clarifications will complement what you wrote:
Approach climb - From CS-25.121(d)(1):
The steady gradient of climb may not be less than 2·1% for two-engined aeroplanes, 2·4% for three-engined aeroplanes and 2·7% for four-engined aeroplanes, with –
Landing climb - From CS-25.119:
In the landing configuration, the steady gradient of climb may not be less than 3·2%, with the engines at the power or thrust that is available 8 seconds after initiation of movement of the power or thrust controls from the minimum flight idle to the goaround power or thrust setting
Regarding CS-25.119 - since the landing WAT-limit weight is the lesser of the weights limited by 25.119 and 25.121, and for many airplanes, twins in particular, the one-engine-inoperative requirement is the limiting one, it is quite common that full G/A thrust is not achieved within 8 seconds, although the required gradient of 3.2 % is.
