Thank you all for great feedback,
The situation and questions arise from a lesson in performance.
Talking about the different required gradient for certification for the 4 stages.
For this I assume still wind,
As for day to day operation and obstacle clearance it is evident that wind does affect our flight path and Is taken into consideration...
I initially reacted to a simple statement ..
Headwind increases your climb gradient
Well yes if speaking about obstacle clearance.. (ground referenced gradient)but NOT when considering your climb gradient of whatever depending on number of engines
I still maintain that without specifying what the gradient gradient is referenced to. The aforementioned statement is incorrect..
What I have learned sofar, is. Perspectives from either side of the pond as well between mil & civil pilots differ..
We all achieve the same outcome , but our verbiage to describe what we are doing seems to be different.. perhaps it is a context issue too..
I am adamant to get to the bottom of this simple conundrum, so please continue to give feedback
