There will be some slight hesitations when new tiles are loaded.
It's possible that a large dt could cause you to overshoot your
target. If you factor dt into your control algorithm (if it's not
already) that might help? I'd take a close look and see if dt
spikes at the same time as your anomolies.
Okay, here is the point of the discontinuity. This is data on the FG
side that is being sent to the sim
and the point of the speed change (first number is just a frame
counter for reference)
2874 249.876
2875 249.877
2876 249.876
2877 249.876
2878 249.877
2879 249.876
Altitude = 60
Temp at alt (C) = 17
Temp sea level (C) = 17.118
Altitude = 60
Dewpoint at alt (C) = 7
Dewpoint at sea level (C) = 7.012
2880 262.848
2881 262.848
2882 262.845
2883 262.841
2884 262.837
2885 262.833
2886 262.825
2887 262.822
That output is from the real time weather fetcher. If the winds
change when new weather is fetched, that could account for an
instantaneous speed change (relative to the local airmass.)
A change that large (13 knots!!) is a major wind shear.
Might it make sense to provide some sort of filtering or extrapolation
between stations to moderate such extreme changes
