Buttons and Knobs
The buttons and knobs on a SkyView HDX display are used for various functions, including
powering the unit
ON
and
OFF
, accessing and navigating menus, selecting or activating
features, and adjusting values.
Buttons generally require a single action (i.e., momentarily press). Pressing the button will
provide a distinct tactile click response to the pilot. The click occurs when the button is fully
pressed, but the action does not occur until the button is released. When a button is pressed in
this manner, a function or action denoted by the label above the button is invoked. Button
labels are contextual and may change dependent on menus and feature control pages the
pilot selects.
A button has a function if a label displays above it. If there is no label, then no function is
available. Some buttons have additional behavior when the button is pressed and held down for
two seconds. An example is Button #1. When you press-and-hold Button #1, the SkyView HDX
display will power
ON/OFF
. Additional press-and-hold behaviors for other buttons are described
in the
SkyView HDX Airplane Flight Manual Supplement
document.
Knobs can be rotated in both directions and pushed. The current knob function is indicated by
the label above the knob. Knob function is contextual and can change when the contents of the
screen is changed by the pilot.
Figure 7: Knob Rotation and Button Push Actions
On some screen pages with both vertical lists and a horizontal group of tabs, one or both knobs
can exhibit a push and rotate behavior which controls horizontal scrolling of the cursor across
rows and columns on some menus.
