I checked out the tutorials, but i didn't see (or i couldn't find) this particular question. Why is it when my STAR has a waypoint that say is 14,000A. I know this is the symbol for Above, but if i execute this procedure, on any VNAV decent, the aircraft will never meet the restriction, one time it passed the way point 10,000 ft above the way point, and the VNAV path sky rocketed down to like 6,000 ft/min. If i do a 14,000B everything works as it should.
