While working on the plugin feature and looking through the mission planner source code, I noticed that there is _lowairspeed property defined in HUD.cs :
[System.ComponentModel.Browsable(true), System.ComponentModel.Category("Values")]
public bool lowairspeed
{
get { return _lowairspeed; }
set
{
if (_lowairspeed != value)
{
_lowairspeed = value;
this.Invalidate();
}
}
}
when this variable is set to true, the airspeed text is drawn in red on the HUD.
However, I couldn’t find any configuration option in mission planner related to this code.
It seems that this code reserved for future use, but I would like to confirm that I’m understanding this correctly.
