I'll change all of my AP glideslope behaviors , the hacks are usually because I haven't found any documentation , so I go with a rough guess. I have come across information that states that on some systems , the glideslope will not capture until the localizer has been. I also use the "has-gs" when

Two (unrelated) glideslope things: 1) I tested making the has-gs property be based upon the GS range check (leaving aside any discussion of how GS reception range should be calculated). This is good, because existing panels generally use has-gs as a 'valid GS signal being received', to un-pa
