alf5071h Yes, JEPPESEN publishes it somewhere in the beginning of the enroute section i believe. NACO publishes it aswell, on the inside of the back-cover page.
For operational use i would definitely suggest that aswell.
wilcoluca I was wondering why you want it from percentage -> descentrate, not angle -> descentrate? Usually on charts the angle is published, not the percentage.
