SV-EMS-220 Engine Monitoring System Installation and Configuration
SkyView HDX System Installation Manual - Revision E 10-27
• The color yellow is used to indicate either a cautionary range where limited operation
is permissible as directed by the airplane manufacturer's documentation. An example
of compliance with the precautionary range requirement is the yellow arc marking on
the carburetor air temperature gauge to indicate the range of temperature where
carburetor icing may occur.
• The color green is used to indicate a normal condition for operation, both ground and
flight. Where applicable, the high value end of the green arc should indicate the
maximum limit for normal operation, and the low value end of the green arc should
indicate the minimum limit for normal operation. Where appropriate, there may be
blank gaps, or other colors, inserted into the green arc. Either the upper or lower end
of the green arc may extend to the red radial or stop short of it as appropriate to the
measurement being marked. A wide green arc and a narrow green arc may be used
to denote a normal all-engine range and a normal engine-out range, if appropriate.
Apply the colors and values exactly as defined in airplane manufacturer's documentation.
In some case, gaps may appear between the red colored limit, and the green colored
normal operating range. These gap ranges, when they occur, can be colored any color
you choose, except Red, Yellow, or Green.
The order that ranges are configured has no effect on the functionality or display of the
gauge. Ranges are defined with the following properties: enable, color, top, and bottom.
Enable is used to tell SkyView if that range is on or off. If it is off, it will not be considered
or displayed.
Each gauge can consist of up to five (5) ranges. If fewer ranges are desired (such as a
contact), set the unneeded ranges ENABLE: NO. Each range has an associated color:
Black, Red, Orange, Yellow, Green, Blue, Violet, White, or Cyan. If a range is not defined,
it is considered black, so there is not generally a reason to configure black ranges. If
ranges overlap, the following rules apply:
• Red trumps Yellow.
• Yellow trumps Green.
• Green trumps Blue / Cyan / Orange / Violet / White / Yellow (these are equal
priority).
• Blue / Cyan / Orange / Violet / White / Yellow (these are equal priority) trumps
Black.
For example, you could set up two (2) ranges for the same gauge, each 0-10, one (1)
Red, and one (1) Green, and that range would be Red. To further illustrate this behavior,
if another range for that same gauge was configured from 5-15 and set to Yellow, only
10-15 would be Yellow.
The two (2) edge ranges are considered to go on "forever," so if a gauge is set up as
Yellow from 10 to 20 and Red from 20 to 30, and the sensor reads 35, it will still be
considered Red since that is above the highest range. It will be considered Yellow below
10. If you wish for this not to occur, you must make your edge ranges Black.
