Thank you for your answers guys, but sometimes there isn't any fix or altitude promulgated, have a look at this plate
On CNA5P dep, we do have 4.8% to maintain until 666ft that's clearly stated, but then 8.6% as a minimum for the entire SID? well when we accelerate to retract flaps we are well below 8.6%. Could it be airpace related and not obstacle related ?
