How many degrees?

[phjvh 0]

A bit lost in goniometrics.

Have all sides, so with some formulas one can get the value of the angles with a table or calculator.

Even more easy, it is about right triangles.

So eg. sinx=1/2, so x=30 degrees.

And now tgx=a/b; is it possible to get x in xml?

I'll give you x right here... now... more seriously... depends on what x represents, wouldn't you agree?

You are right, wrong synthax?, but i believe that you know what i mean.

 

Has to do with the radar position of an AI in a vertical plane, see "radar" subject.

Distance and bearing gives movement in the horizontal, while distance and altitude-difference should give movement in the vertical.

And here comes the angle: tg "of wanted angle" = alt-diff.nm/distance.nm (both known data)

What is now the angle?

Is this what you are looking for?

 

Angle equals arctan a/b, xml is: a b / atg rddg

 

but I figure you already know that ....

Altitude (in feet) / distance to AI (in feet) = tangent(angle).

 

So... is your question regarding whether there's an arctan function or are you asking if FS provides you with the value of the angle itself already?

Thanks, got it.

Forgot the a...
