SYSTEM OVERVIEW
1.6 SYSTEM OPERATION
The displays are connected together via a single Ethernet bus, thus allowing for high-speed communication.  
As shown in Figure 1-1, each GIA 63W is connected to the on-side PFD.  This section discusses the normal and 
reversionary modes of operation as well as the various AHRS modes of the G1000 syst\
em.
NORMAL OPERATION

SYSTEM OVERVIEW
REVERSIONARY MODE
 NOTE: The G1000 system alerts the pilot when backup paths are utilized by the L\
RUs.  Refer to the Appendices 
for further information regarding system-specific alerts.
Reversionary mode is a mode of operation in which all important flight informatio\
n is presented identically 
on at least one of the remaining displays (see Figure 1-10).  Transition to reversionary mode should be 
straightforward...

SYSTEM OVERVIEW
AHRS OPERATION
 NOTE: Refer to the Appendices for specific AHRS alert information.
 NOTE: Aggressive maneuvering while the AHRS is not operating normally can degrade AHRS accuracy.
In addition to using internal sensors, the GRS 77 AHRS uses GPS information, magnetic field data\
 and air 
data to assist in attitude/heading calculations.  In normal mode, the AHRS relies upon GPS and magnetic 
field measurements.  If...

SYSTEM OVERVIEW
GPS INPUT FAILURE
 NOTE: In-flight initialization of AHRS, when operating without any valid source of GPS data and at true 
air speed values greater than approximately 200 knots, is not guaranteed.  Under these rare conditions, it 
is possible for in-flight AHRS initialization to take an indefinite amount of time which would result in an 
extended period of time where valid AHRS outputs are unavailable.
The G1000...

G1000 SYSTEM ANNUNCIATIONS
 NOTE: For a detailed description of all annunciations and alerts, refer to Appendix A.  Refer to the Airplane 
Flight Manual (AFM) for additional information regarding pilot respons\
es to these annunciations.
When an LRU or an LRU function fails, a large red ‘X’ is typically displayed on windows associated with 
the failed data (Figure 1-14 displays all possible flags and responsible...

SOFTKEY FUNCTION
The softkeys are located along the bottoms of the displays.  The softkeys shown depend \
on the softkey level 
or page being displayed.  The bezel keys below the softkeys can be used \
to select the appropriate softkey.  When 
a softkey is selected, its color changes to black text on gray background and remains this way until it is turned 
off, at which time it reverts to white text on black...
