Avidyne Entegra - Normal Startup Sequence; System Power

2-2 Normal Startup Sequence
2 Normal Startup Sequence
SYSTEM POWER
The IFDs and keyboard will automatically start when the aircraft
bus power is applied.
After power application, the keyboard display will be visible as
well as the Brt/Dim rocker key on the IFDs. Several seconds later,
the IFD displays will begin to have indications.
There are no On or Off controls for the equipment, each IFD is
regulated by a pair of circuit breakers. Both units would need to
be disconnected in order to remove power and is not something
expected to be performed for normal operations. The keyboard is
regulated by a single circuit breaker and fed by the essential bus.
BRIGHTNESS CONTROLS
Each IFD has its own brightness control on the bezel to control
the individual display brightness. Power-on brightness of both the
IFD displays and the keyboard display will be 100% – there will
be no need to increase display brightness. Bezel background
lighting is controlled via the cockpit dimming controls/rheostats.
STARTUP INDICATIONS
During normal start up conditions, there are no special startup
screens or displays that appear. The PFD will present an Attitude
Heading Reference System (AHRS) alignment box in the upper
half of the display and the MFD will present the Initial Fuel view of
the Engine tab.
AHRS alignment time is approximately 2 minutes and 45 seconds
from the time the AHRS alignment box is displayed on the PFD.
