TOUCH SCREEN
The IFD uses a capacitive touch screen technology that allows
multi-touch operation (e.g. two-fingered pinch zoom). Many types
of gloves can be used during touch screen operations.
The IFD employs a “hybrid touch” design in that virtually every
interaction can be accomplished either through bezel controls or
touch. This allows for flexibility in operational use. Some
features or functions naturally lend themselves to being easier to
accomplish through touch (e.g. map panning) and some are
naturally easier to do via physical bezel controls (e.g. changing
pages or using dedicated functions like the frequency list). Hybrid
touch is useful during turbulent or bumpy flight conditions where it
is often very difficult to precisely and reliably touch the desired
point on the display. Having a physical bezel control provides an
“anchor point or control” to hold on to and exercise the intended
action.
TIPS AND TECHNIQUES
Turn off the touch screen
The Setup Page provides an option to disable the
touch screen. This can come in handy in
excessively bumpy flight conditions when even
attempting to use physical bezel controls can result
in inadvertent touching of the screen and potentially
causing unintentional display changes.
Touch zone targets have been intentionally oversized wherever
possible to aid in accurate touch screen behavior.
As noted above, virtually every feature or function of the IFD can
be accomplished either by touch or by physical bezel control.
The following table identifies the exceptions to that rule:
