Turbulance

[Bando]

I got a question.

It's been 13 years since I've flown as a crewmember in a naval helicopter.

I remember turbulance. Once flown with 120 knots (on a day without much wind) into the vortex of an Orion MPA, that was no joke at all. I thought initially we lost the main rotor.

 

The turbulance in game is something else.

I cannot remember it being like it is in game now.

I'll admit that most of my 3.500 flying hours (as a crewmember) were above large quantities of salt water, there was turbulance now and then.

Maybe a helicopter flies different in turbulance compared to a fixed wing, but it seems strange to me that with 4m/s turbulance set, I am thrown around like I am in game.

 

Any of you pilots can comment on this? Is this like it is out there?

[4H_V-man]

There are people here with more flight experience than I have, but I'll throw my two cents worth in. I've never held a pilot's license, but I have flown a Cessna 150, 172, 182, a Beech Bonanza, and last year I got to take the controls of a WW II era BT-15. I'm not sure exactly what 4 m/s turbulance equates to as I am not a user of the metric system, but the day I flew in the BT-15 it was fairly windy and very rough. It was quite an exercise keeping the aircraft pointed where I wanted and keeping the wings level in level flight was not very easy. It was next to impossible to keep the slip ball centered, but the pilot told me that under the conditions I did a good job handlling the plane. In my opinion, it was VERY much like BoS represents turbulance. I still think ground handling needs a bit of work, but in flight seems to be pretty acurate to me.

4 meters/second = 8.94 mph.

 

Sounds to me like something is amiss.

I might be mistaken (probably), but I thought that "rough" turbulence was often the product of micro or macro air-pockets.

You could have turbulence caused by wind, and/or turbulence caused by pressure fluctuations.

No

[Bando]

Well, thx for answering.

Turbulent air will rock any aircraft, but the way it is implemented in game seems a bit too rocky to me.

I was seeking conformation, and I did not get that, so I'll assume you all think this is normal.

 

For all those that hesitate:

Go try out there with a stuka and start on the platform with 15m/s or more wind (you'll have quite a challenge to taxi to the runway) and 6 m/s or more turbulence and see how many tanks you kill.

[AndyJWest]

I'm not sure that describing turbulence in metres per second tells you much. Even if one assumes that the figure is 'maximum gust velocity', one will have no idea of the rate of change of velocity and/or direction over time. 

[Bando]

I agree, but it is some sort of slider in game now. With more than half (5m/s) the planes become very difficult to control especially when trying to make a pinpoint attack.

I think it should be toned down considerably, but I am not sure how much and therefor I asked the forum.

[Sandhill]

I don't think that we know what the m/s figure represents...I had assumed that it was some sort of measure of shear or reversal of velocity, but even if that's what it is, as AndyJ points out we really don't know over what distance or time it occurs.  The scale for turbulance goes 0 to 12, so 5 is about 42% of maximum..  I haven't played with it much, but perhaps higher values would be a more appropriate challenge for heavier planes?  In any event, if a setting of 5 seems too high, you could always try 4.  A 15m/s crosswind SHOULD be qute a challenge, it's (at over 33 mph) way above the recomended takeoff or landing limit for many aircraft...

Do you want to know what turbulence is?? Do what real pilots do!! Take a look on official documentation

OK, thx.

So I did read this.

They are talking about different kind of causes for turbulence.

Most are not present in our game environment. Maybe the turbulence caused by jetstream at high levels is there. Thunderstorms are not in the game as such. The wake turbulence of another aircraft is superbly modelled in game and not all that severe. Mountains causing turbulence are not present around Stalingrad. So where is that severe turbulence coming from?

 

I guess (here we go, guessing again) that above the land climate of inland Russia there is some low level turbulence as the sun heats up some spots more than others. Gliders know all about this.

The severity of the turbulence in game is way more than I would expect.

[andyw248]

In any case, in my experience turbulence will be encountered either when the air is hot and the skies are clear (e.g. in summer in the desert), or when a cold front approaches (which is common e.g. in the Pacific Northwest, or in Western Europe). Both kinds of turbulence make for challenging approaches and landings - it's hard to keep the aircraft on speed and at a defined rate of descent; basically the needles will jump. Videos of landings in turbulence will show the pilot jerking around the stick or yoke.

 

In dry winter climates (e.g. in winter around Stalingrad) there typically isn't much turbulence; except when a cold front is coming in - see above. When a warm front approaches there isn't much turbulence either.

 

Another kind of turbulence can be experienced on sunny summer days, typically with small cumulus clouds around. On those days we keep flying from updrafts into downdrafts, and so on.

[andyw248]

On the other hand, there's always some turbulence, even on an otherwise quiet day. In BoS, setting turbulence to just 1 m/s feels like it would be on a quiet day.

Turbulence so far on this game is an act of god. It is just not connected with anything yet I think.

[HeavyCavalrySgt]

I had a few very violent approaches into Reno recently.  The winds were 24 gusting 29 coming over the mountains and tumbling down into the valley Reno is in.  When NorCal approach gave me a transponder code to put in, I had to try several times - the transponder was ducking and weaving like a boxer trying to make it to the bell.

 

On the way home, I was asked to stay on the lee side of the valley, and there was so much sinking air it took me perhaps 20 miles to climb 2,000 feet and I was seriously concerned about being outperformed by some mountains.

 

Also, low level wind shear on short final, as I recall.

 

Yesterday, flying along 80 towards Reno, I kept getting these huge gusts of wind from the south that would roll the airplane into a 15 or 20 degree bank, despite full aileron the other way.  It was only moderate turbulence, just really gusty.

I fly light aircraft in real life and turbulence can be persistent and violent. In mountain finals I was dropped 5 metres (it felt like 10) and passing a helicopter spinning up at the side of the runway I've been kicked sideways what felt like metres. Personaly I like the floating bumpy ride in BOS/ROF. However the wind and turbulence that you feel in the mission has been set by the mission writer in the mission editor not god.

 

You can control the direction and speed of the wind in the mission editor at different altitudes by degrees 0-360 and by M/S. This is not turbulence. One note is that the degrees have always been the opposite of a weather report. If you are copying real weather and it says 90° set it to 270° in the editor.

 

AFTER this you set turbulence as a factor from 0-10 (which is not M/S). For most missions I set it between 1-4 which will give you from smooth to a bumpy ride. I have not tested 9 or 10 but suspect it will be quite violent.

 

Of course this is using the ROF mission editor but you can trust me that BOS mission editor will probably be very similar.

 

If you have been flying a qmb mission in BOS search your computer for a new .Mission file. Open it in a text editor and search for "Turbulence =" then you will see what it was set to.
