So I feel like a complete dumbass, but I'm not quite sure I've got this calculation down correctly. I remember something from ERAU telling me I'm supposed to slide the ISA line to the right and intersect the red arrows I've put on the attached chart, but I really don't remember.
It's from a Duchess POH, and I'm looking for Absolute SE service ceiling. Did I do this correctly?
