How can I calculate AI Aircraft location from FSUIPC?

[arnthelge]

Hi,

I am trying my best to make a little utility to keep track of active AI aircraft in the area. It is supposed to be some what a traffic board for AI spotting.

I have managed to read values like GS, VS, HDG. Now I am trying to figure out how to read latitude, longitude and altitude for AI aircraft. I cannot seem to find out how. The FSU SDK says:

float lat; // 32-bit float, in degrees, –ve = South

float lon; // 32-bit float, in degrees, –ve = West

float alt; // 32-bit float, in feet

I have read the four bytes, but where do I go form here? How do I convert the 32bit float into lat, lon and altitude?

Hope someone can help me... :shock:

Regards,

No conversion is necessary. The values are 32-bit floating point values, which are supported as standard on all Intel type PCs. They already are latitude, longitude (both in degrees) and altitude (in metres), as described.

You should read them into variables declared as float (for C/C++) or whatever the equivalent is in the language you are using. If it is not C/C++ please look up in your programming book to find out about floating point numbers and how to declare them and use them.

Thanks Pete,

I finally managed to figure out how to read it in VB. :D
