Operating Instructions
Basic operation of EFD1000 E5 is covered in this section. For detailed operating instructions see the
E5 pilot’s guide.
12.1
Pilot Controls
12.1.1
Overview
Pilot interaction with the EFD1000 E5 is accomplished through two knobs with
push/rotate function and 11 buttons located on the display bezel.
Two control knobs are used to control pilot settable bugs and references.
The center lower push button, located between the control knobs, is used to select
navigation sources.
Three dedicated buttons on the upper side of the right bezel provides access to the main
menu.
Five soft keys on the lower half of the right bezel control frequently used commands.
The soft keys are also used when navigating the main menu and for enabling the right
knob for barometric pressure and VSI bug (when configured).
12.1.2
Power Control
To enhance safety, the EFD1000 E5 includes an internal battery that allows the system to
continue to operate in the event of a failure of the aircraft electrical system.
The typical EFD1000 E5 installation receives aircraft power from the battery bus via a
dedicated circuit breaker and EFD1000 E5 Master switch.
Whenever indicated airspeed is invalid or below 30 KIAS the EFD1000 E5 will power up
and power down with the application or removal of external power. A message is
presented during the normal power down sequence to enable the pilot to abort the
shutdown and switch to internal battery.
When IAS is greater than 30 KIAS and the input voltage drops below 12.3V (14V Electrical
System) or 24.6V (28V Electrical System) the EFD will automatically switch to its internal
battery (e.g. aircraft charging system failure).
The EFD will also switch to internal battery if an overvoltage condition is sensed.
The EFD internal battery provides power to the display head and RSM. Reducing the
backlight intensity will extend the battery operating time.
When operating from battery, a red “ON BAT” annunciation and battery charge status
indication is presented in the lower portion of the Attitude Indicator.
A unit operating from battery may be powered off using the “Shut Down” command
available in the Power Settings Menu.
