Navigation - How to obtain magnetic bearing

[Felix58]

A brief video of a method of how to obtain a magnetic bearing in BOS prior to the introduction of in-game tools.

Actually good question. I flew the other night from the russian base to the West of Pitomnik heading east in a Pe-2 trying to find Pitomnik. I was heading 090 and yet the rising sun was about 15-20 deg to my right. Surely the magnetic variation wouldn't be THAT large so close to the North pole (as Russia is)...unless I'm missing something.

Thank you.

Actually, Stalingrad is at the same latitude as Paris (about 48.5° N)

:-)

and magnetic declination is 8° to the East.

Additionnally, Sun does not always rise exactly east (only on equinoxe).

Something else I discovered when testing this.

 

After take-off engage the auto-pilot - LSH A

 

Press and hold LSH Z (left turn) or LSH X (right turn) until the desired course appears.  

Sometimes it appears that nothing is happening initially, so be a little patient.

It may take a bit of time to get used to adjusting this, but worth the time.

Much easier to check map-to-ground with the auto-pilot on.

Yep, for Europe, in winter the sun rises in the south east, doesn't hang around and sets in the south west. The sun is always always always somewhere to the south. A navigational aid I tried many times to imprint onto my ex-wife, to no avail.  In Summer, though, the sun pulls a fast one, gets up in the north east, makes itself at home, outstays its welcome while its looping south, and sets in the north west.

ah ok. if the devs have designed BOS to this level of detail...thats just awesome!!

[gabuzomeu]

I'm sure they did model it, and the time of sunrise as well: to check you can go to suncalc.net which will give you on a map all necessary info on Sun rise, set, direction etc... on a given date (even in 1943)

Lol,I know what you mean buddy.A few years ago I was trying to explain something like this to my wife as she thinks North is the way that your facing at any time. 

 

She demonstrated this by turning 180 degrees and saying "so this is North now?" I just gave up.

Magnetic variation for Stalingrad was 6° 47' 52" E in December 1942. So, in order to fly a course of 90 degrees (true east), you would have to subtract about 7 degrees from it, which would put you on a heading of 83 degrees (assuming no crosswind component).

Magnetic compass variation, deviation and correction

Bad picture quality but instructional

I feel so dumb.

 

Anyway, gonna try to make use of this. Really interesting info.

Yes, the sun is always to the south due to the high latitude of the battle area. 

 

Or, it could be that you are way to the west, beyond where the sun sets, so the sun is now setting in the east, causing confusion (City Slickers II).

Speaking of navigation, what scale does the BoS map use?

[andyw248]

Each square on the map has a side length of 10 km:

 

 

This can be calculated by measuring the direct distance between two points on skyvector, e.g. between Gumrak and Morozovsk, and then triangulating the distance in squares between those two points on the map.

Is ther eactually a proof that declination/variation is implemented ingame? I'd be very interested to knwo since I couldn't notice it by now when navigating and doubt it's nessety in a flight sim (of course it would be great detail to have, but so could be deviation, compass rotation erroring (sry if this is the wrong term for it in english) ect.).

Excellent, thank you!

I also used the magnetic variation technique in CLoD and it worked perfectly there as well.  I daresay the Mag Var may not have been exactly 10 degrees at the time but it gets you close enough, especially flying without auto-pilot on.

 

I have used the technique for minor hops, eg, Beketovka to Pitomnik (349) and it works well.   

 

Combine this with time over distance, map to ground and you can get quite accurate where you are at any given time.  Lot of fun actually.

[Mastermariner]

The magnetic declination can for practical purposes be regarded as a constant, providing the compass is used in a comparatively small area such as the Stalingrad map, and can thus be taken out of the equation by adjusting the compass rose. This is frequently done in pleasure boat compasses.

 

This was unknowingly done when the first compasses were constructed, a compass made in Lisbon showed true north there and a compass from Turkey showed true north in Turkey, but if they switched places they were of.

 

The declination varies over time but we can disregard that.

Yes, declination at least is modeled, as it is in RoF. Matter of fact, in RoF the night sky is detailed enough to navigate by if you are familiar with constellations. I haven't checked BoS yet, I'll have to try it.

Downloaded Screen Scales. Download has no information on how to set-up, install or where the place the files. I have not found anything on the internet on how to install Screen Scales. Everything I've tried does not work. Does anyone have information on how to install Screen Scales.

Just double clic on the "xxx.air". It needs air application from Adobe (most of the time already on system).

FWIW Volgograd Airport as shown above is of course Gumrak in the game.

anybody knows if the stars rotate? otherwise they can be used as a navigation exploit, just follow that star till the sun rises

No, Raaaid, the stars do not rotate. However, the earth DOES rotate and that causes the stars, sun, and moon to move across the sky. Here's a helpful link for you:

Thanks for the info KpaxBos. The Softpedia download did not include the ScreenScales application exe. The link you provided includes a link to the creators website. For those that want to use SceenScales, look for "Go here and click install". When ScreenScales runs, it wiil place a couple on points on the desktop. Left click one of the points and select "Always on Top" to have ScreenSavers appear on Paint, etc.

Ditto.

I'll make sure AIR is installed.
