External Display
If an external traffic display is being controlled by the GTN, it will be
commanded to match the display settings on the GTN (traffic range and altitude
filter). In a dual GTN installation, GTN #1 will control the external display.
The traffic range on the external display will be set to the nearest range to the
selected range on the GTN.
