Sorry, my FIRST reply was sent unfinished by accident! Here is the right one :-)
-------------------------------------------------------------------------------------------------------------- Due to the special weather conditions tonight (only IFR possible) the formerly described effect was very reduced but still visible (!). So the trace (appended) might not be usefull, at least I cannot see anything obvious. I will do another test within the next days with other local METAR values. Therefor my answers to your question are mostly related to former observations: > > Could you explain what you are seeing in terms of wind direction and > strength? Is it: > - oscillating in direction and/or speed > - rotating continually? > - chaotic? Normally oscillating > Are you seeing the problem generally, or only when the METAR changes as > you fly from one zone to another? > Generally, directly after starting from the airport. But - as already mentioned in a former mail - I have to set "--enable-real-weather-fetch". Without this there are no problems visible. > If it is easily reproducable, Seems depending on the METAR conditions - is there but with different strenght could you run with the following > command-line parameters and post the results, either to the list or > directly to me: > > --trace-write=/environment/metar/real-metar > --trace-write=/environment/metar/base-wind-range-from > --trace-write=/environment/metar/base-wind-range-to > --trace-write=/environment/metar/base-wind-speed-kt > --trace-write=/environment/metar/gust-wind-speed-kt > --trace-write=/environment/config/boundary/entry/wind-speed-kt > --trace-write=/environment/config/boundary/entry/wind-from-heading-deg > > If you could also describe the specific flight that repros the problem > that would be most helpful. > No specific flight. Mostly from EDDV to EDDW or EDDW to other local airports. I used Bo105, PA 24-250 and PA 28-161. > > > Once again, my apologies if this has spoilt anyone's flights.
