Here is a little patch that changes the behaviour of the VOR CDI and OFF-flag for indicators like the HSI when getting outside the range of the VOR station. Currently, when flying at a distance between the effective_range and twice the effective_range of a VOR station, the in-range property is computed based on a random value, causing the OFF Flag and the CDI bar to perform an ugly jitter. The attached patch introduces a new property signal-quality-norm which is computed based on the distance to the station and the range. It is 1.0 when the distance is less than the range and decreases by 1/x^2 for distances greater than the range leading to a signal-quality-norm of 0.25 for distances two times the range, 0.125 for three times the range and so on. The in-range flag is tied to a signal-quality-norm greater than 0.2 (fixed squelch). The CDI and GS needle deflection is multiplied with the signal-quality-norm. The benefit is: - Ability to animate the OFF-Flag with a smooth transition. - CDI and GS needle deflection shows correct values when in range (signal-quality-norm=1.0) and show some wrong indication when the range is exceeded - CDI and GS needle start to move, even when the OFF flag is visible - No more jitter for flag and needles See the new SenecaII ki525a hsi as an example at http://www.t3r.de/fg/navpatch.jpg The numbers on the image are: (1) the new property signal-quality-norm (2) distance exceeds the effective-range by 30% (3) NAV flag has a rotation animation bound to signal-quality-norm and is partially visible (4) CDI is partially deflected even with NAV flag shown This implementation better matches reality - at least, how I observed it ;-) |
