HN39 or takata:
Does the graph (
http://www.pprune.org/tech-log/45687...ml#post6621344 ) take into account, or synchronize with, the change in heading to the right over the course of the descent, which would thus vary the airspeed depending upon what winds were at a given level ... or, did you average the winds from what data is known to get the airspeed numbers from ground speed?
