I'm having problems understanding the variables that drive the Glideslope and Localizer needles, and secondly the math with animating them.
I take it these are the variables that would drive the glideslope animation?
HSI GSI NEEDLE
and for the localizer:
HSI CDI NEEDLE ???
All I have so far is a needle animated 0-360 frames, however it doesn't move:
<PartInfo>
<Name>localizer_needle</Name>
<AnimLength>360</AnimLength>
<Animation>
<Parameter>
<Sim>
<Variable>NAV LOCALIZER</Variable>
<Units>number</Units>
<Scale>1</Scale>
<MinValue>0</MinValue>
<MaxValue>360</MaxValue>
</Sim>
</Parameter>
</Animation>
</PartInfo>
Any help is greatly appreciated.
