2.2. Controls
The primary means for the pilot to control the EFI are the two knobs and center button
at the bottom of the display. The knobs control setting CRS and HDG, and additional
bugs and altitude settings. The lower center button control selection of navigation
sources for the CDI. There are center button controls above the Hot Keys to control
entering and exiting the Menu and Reversion or Manual Power Control.
Five Hot Keys to the right of the Navigation Display toggle various features on and off.
The function of each is indicated by the label on the display to the left of each key.
2.2.1.
Left and Right Knobs
The Left and Right Knobs are designed to provide immediate operation yet minimize
the possibility of an inadvertent operation. This is accomplished by requiring that the first
action of the knob “wakes up” the knob and changes the label from cyan to magenta.
The first click when the knob is turned or the first press on the knob, “wakes up” the
knob function.
Press the knob more than once to cycle through its Menu options in a round-robin
sequence or press and hold the knob to synchronize (SYNC) the function’s value
(see
Section 2.2.1.3. SYNC Function).
After 10 seconds of inactivity, the knob returns to its
default setting.
