Working on a cockpit and wonders if its true that it works max to 304?

<table border="0" align="center" width="95%" cellpadding="0" cellspacing="0"><tr><td>Code Sample </td></tr><tr><td id="CODE"> class IndicatorAltRadar
{
// max for this indicator is 1000 feet &#40;i.e. 304m&#41;
// note&#58; this is actualy Baro altitude &#40;name is wrong&#41;
selection = &#34;alt&#34;;
axis = &#34;osa_alt&#34;;
angle = -360;
min = 0;
max = 304;
};[/QUOTE]

Want to have angle -270 and then max should be 900 meters, is it impossible or just me thats stupid?
