Say i am in cruise with one engine and i plan my approach for landing.
What way do i have to ensure my performance during go around respect said limitation? Only thing i can think of is literally checking the estimated EO gradient (which is checked per altitude) on flysmart, getting the feet per minute and checking that i fits under 10’.
It was a bit of tread hijack... but yes, the guessing of how much time would be needed is a good place to start (I've even known a company where checking the 400fpm single engine ROC was almost a callout).
Anyway, can only speak for myself and how I plan such "approaches". There will always be a "worst case" plan in my head purely based on terrain for the remote case the aircraft would really struggle with the required climb performance. Ie a runway centerline is always a fairly safe place up to final approach fix (and even following procedure turns opposite direction)
