Yes - allmost. But please don't clamp the xxx-deviation-deg to +/-10.0 or +/-0.7. When I look at my KI525a HSI (real life, not simuland), the glideslope markers move out of sight when I am more than 0.7deg off the center of the glide slope. That will be hard to model when the values are clamped to +/- 0.7. In other words: The glideslope receiver notices deviations of more than 0.7 degrees off center, only the display shows the range of +/-0.7deg. The CDI needle can move a little further out, than the outermost dot on the scale. Here, also the receiver detects offsets of more than 10deg, just the display is limited to full deflection. So my question is: why clamp the xxx-deviation-deg properties at all? Shouldn't it be a duty of the instrument to define where it hits the border? Torsten |
