No. The standard design is based around 3 degrees slope. With that design, the usable range is 1.4 degrees high, from 2.1 to 3.7 degrees and offers 0.35 degrees per dot. Therefore, a dot equals 50ft per mile range from the touchdown zone of the runway. When the standard design is scaled for terrain or other approach spaces, all that is modified is where the antenna array has the intensity maximuma. Consequently all those numbers grow by up to 8% or shrink by up to 16%.
>From the point of view of implementation in a simulator, just take the actual slope number for a specific runway and combine that with the aircraft's position to generate a ratio. Repair the ratio to allow for the side lobes (which as I recall are the standard series with a negative at 6 and one you can follow at 9). Then pass that ratio to the instrument implementation. The instrument should probably show full scale from 0.6 to 1.4 with center at 1.0 and dots at 0.77 0.88 1.11 1.23 On Fri, Jan 2, 2009 at 2:09 PM, syd adams <adams....@gmail.com> wrote: > Ok , Im getting closer...i think > Another manual i have states min glideslope angle = 2.5 degrees , maximum = > 3.25 degrees, > so does that mean the needle animation range should be 0.25 at the upper > second dot, and -0.5 for the bottom second dot ? > That approach illustration is really confusing me now :) > > > ------------------------------------------------------------------------------ > > _______________________________________________ > Flightgear-devel mailing list > Flightgear-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/flightgear-devel > > ------------------------------------------------------------------------------ _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
