Ok… In my earlier post I gave an example from an EFB calculation, but maybe I didn’t explain my question clearly. I understand that we have to comply with the WAT limits (approach climb OEI and landing climb AEO), which is also why Boeing asks us to check them in the overweight landing NNC.
What I was really trying to understand is the MACG part. If the aircraft meets the WAT limits but cannot achieve the required missed approach gradient for the procedure (say 2.5% or whatever is published), what would the operational decision normally be? Would the approach need to be avoided, or is there another consideration?
(Hopefully I’m not just missing something obvious here, I feel like I may be repeating the question but I still haven’t quite cleared it up).
