Thanks OldHat, Hope this isn't too much to ask.

I tried a full campaign flight and speeded it up in autopilot with the intent of taking over once I saw some turbulence but I never got any.

I would very much like to have this feature you are working on. My other question is whether you got it to work in QC.

It seems that wind that affects lighter crafts do not affect the heavier ones. There is a balance I have to reach to avoid severely tossing a Morane in order to get an SE5 to budge.... Back to more testing.

In the meantime, if you can test the same file flying a Morane, that would be great. Remember to make sure you edit the OFF_Camp_Mission.xml file when the Mission Editor Screen pops up. See video below. Skip to 1:11.



I have not tried QC.

OK, that's good to know regarding the heavier craft. I am ok with the instructions, that is no problem. I will try the Morane and the Pup as well.

OldHat;

You are correct. Flying the Morane I encountered significant wind effect both vertical and horizontal and frequent stalling if I didn't keep the nose down in descent when flying into the wind.

This effect was slighly evident when flying the Pup and non existent in the SE5.

I don't know if it will be possible to taylor the wind effect to the type of aircraft you are flying unless one takes the time to constantly adjust the settings in the mod file via ME and your instructions. It might work but will be time consuming I suspect.

You have probably already thought of this issue.

All that being said, I very much like what you have managed to achieve so far.

Cudos!

Best Regards

Maybe I would try to modify the second line of your weather file and change windspeed to 5 or so. This part of code creates "weather strip" of 15 minutes width that repeats every 45 minutes of latitude (north-south).

What about to change all wind directions to west, because western winds prevailed?
What do you think?

Very nice OldHat.

So, I couldn't tell from the video, but do you indeed need to hold a wind correction angle in order to fly a straight course?

That and the prevailing wind constantly blowing you over the German lines would really add two interesting dynamics to the sim.

If it drifts from West to East, that is the correct drift per historical documents.

Note too much wind will cause random problems, obviously testing is the major problem - you may need to check all craft, with without all loads, and fuel loads, on the ground with several runs each on different fields and ditto in formations of mixed craft types, mixed loads. Fun fun. But guys can fly over the next while and see ..

Perhaps I phrased that wrong. Do you indeed experience "drift" with these effects?

I understand that weight will affect the amount of turbulence that you experience. But drift is really more a function of speed. A light piston flying flat out at 100 knots and a twin turboprop hanging on the blades at 100 knots will be pushed sideways equally by a wind of a given speed.

So, as an example, will an aircraft flying south be pushed east by a westerly wind?

My previous experience in WOFF is no. I have never had to slip into the wind to land AFAIK which would be my most direct indicator. Of course for AI landing considerations, it might be that only surface wind is calmed in WOFF whereas you could add a wind layer at altitude which would give you all the problems that the Brits had in getting home from the German side of the lines.

The short answer is, yes. Drift does occur, at least to some extent. Also, groundspeed is affected by whether you have a headwind or a tailwind. In general, however, winds in WOFF are pretty light, ranging from 0 to about 12 mph. Plus, as far as I can tell, WOFF does not model wind gusts. Combined, you aren't very likely to notice much of a wind effect when landing.

You can model this yourself by going into one of the cloud files in the weather folder and changing the wind direction to 90 (representing a west wind), and changing the wind speed (measured in meters per second) to a value of 20, creating a west wind of around 45 mph. Load the cloud file using the auto weather drop down box and start flying. You should notice the wind now.

No, the wind direction in the cloud files is the direction the wind is heading towards, not from where it originated. Check out the original WOFF files. The vast majority are in the 60's to 120's, representing winds coming from the west and blowing east. I originally thought it was like you said, until I confirmed it was not the case.

Thanks Bob. Are you saying that there is wind already modelled in WOFF?

12 mph (about 10 knots) is nothing to sneeze at in these planes. 9 knots of wind from only 40 degrees off had me dancing on one wheel yesterday morning in a Citabria. It's not a gale, but you should notice it pretty readily.

I've never had to cross control in WOFF that I can recall. I can't recall ever really having to compensate for the wind, turbulence notwithstanding.

The wildcard is the DynamicWeather file. I no longer have CFS3 on my computer. Is the DynamicWeather file a program created by OBD?

In any event, when using the Auto Weather dropdown box, the wind speed and wind direction come directly from the cloud type .xml file. What happens under the hood with the DynamicWeather file after that I am less sure about.

I need to do more testing later today before I can comment on what effect the variables in the historicalweather file have on wind speed and direction, although I'm sure they do interact with the DynamicWeather file program.

The DynamicWeather file is the problem. Basically, it takes the wind direction setting located in each cloud type file and slightly varies the direction by a few degrees for several adjacent regions on the map near your flight. However, it ignores the wind speed setting in the cloud file in favor of a wind speed (which also varies slightly from place to place) determined by a number (1 - 6) in the historical weather file. And, generally speaking, the wind speed generated by the DynamicWeather file is usually fairly mild for each weather type. In other words, if we want to increase the wind speeds in the campaign, we will have to alter the wind speed settings in the DynamicWeather file.
