TCAS Conversion Question ?

[FSMIC]

Hi Pete,

With the following data, could you please help.

Newbie in C++ and C#.

I am using the example UIPC_SDK_SHARP from Scott McCrory.

I have only problems to convert float (LAT,LON & ALT) to the values

showned by TrafficLook.

They need no conversion. They are in standard Intel 32-bit floating point format. Just read then into variables defined as such. I don't know C# or VB, but in C and C++ this is the "float" type.

The Lat/Long are in degrees (with West and South negative, East and North positive), whilst the Altitude is in feet.

This is exactly as documented in the Programmer's Guide, where even a suitable structure declaration for C or C++ is provided. Please check there.
