COURSE DEVIATION INDICATOR (CDI)
 NOTE:  During a heading change of greater than 105° with respect to the cour\
se, the CDI on the Arc HSI 
switches to the opposite side of the deviation scale and displays revers\
e sensing.
The Course Deviation Indicator (CDI) moves left or right from the course pointer along a lateral deviation 
scale to display aircraft position relative to the course.  If the course deviation data is not valid, the C\
DI is not 
displayed.

The	
CDI	 can	display	 two	sources	 of	navigation:	 GPS	or	NAV	 (VOR/LOC).		 The	color	 indicates	 the	current	
navigation	 source:	magenta	 for	GPS	 or	green	 for	VOR	 and	LOC.		 The	full	scale	 limits	 for	the	 CDI	 are	defined	
by	a	GPS-derived	 distance	when	navigating	 GPS.		When	 navigating	 using	a	VOR	 or	localizer	 (LOC),	the	CDI	
has the same angular limits as a mechanical CDI.  If the CDI exceeds the\
 maximum deviation on the scale (two 
dots)	while	navigating	with	GPS,	the	crosstrack	error	(XTK)	is	displayed	below	the	white	aircraft	symbol.

Changing navigation sources:
1) Press the CDI Softkey to change from GPS to VOR1 or LOC1.  This places the light blue tuning box over the 
NAV1 standby frequency in the upper left corner of the PFD.
2) Press the CDI Softkey again to change from VOR1 or LOC1 to VOR2 or LOC2.  This places the light blue tuning 
box over the NAV2 standby frequency.
3) Press the CDI Softkey a third time to return to GPS.

The	 system	 automatically	 switches	from	GPS	to	LOC	 navigation	 source	and	changes	 the	CDI	 scaling	
accordingly when all of the following occur:
•	 A	localizer	or	ILS	approach	has	been	loaded	into	the	active	flight	plan
•	 The	 final	approach	 fix	(FAF)	 is	the	 active	 leg,	the	FAF	 is	less	 than	 15	nm	 away,	 and	the	aircraft	 is	moving	
toward	the	FAF
•	 A	valid	localizer	frequency	has	been	tuned
•	 The	GPS	CDI	deviation	is	less	than	1.2	times	full-scale	deflection
GPS	steering	guidance	is	still	provided	after	the	CDI	automatically	switches	to	LOC	until	LOC	capture,	up	
to	 the	 Final	 Approach	 Fix	(FAF)	 for	an	ILS	 approach,	 or	until	 GPS	information	 becomes	invalid.		Activating	
a	Vector-to-Final	 (VTF)	also	causes	 the	CDI	 to	switch	 to	LOC	 navigation	 source.	GPS	steering	 guidance	 is	not	
provided after this switch.

If	the	 same	 VOR/LOC	 navigation	 source	is	selected	 on	both	 PFDs,	 the	navigation	 source	annunciation	 turns	
yellow	on	both	 displays	 (unless	synchronized).		 Once	the	CDIs	 are	synchronized	 (CDI	Synchronization	 turned	
on), they remain synchronized until the setting is changed.  When turning on the G1000 for use, the system 
remembers the last CDI synchronization setting.
Synchronizing the CDIs:
1) Select the AUX - System Setup Page using the FMS Knob.
2) Press the FMS Knob to activate the cursor.  Time Format is highlighted.
3) Turn the large FMS Knob to highlight the CDI Synchronization ON/OFF field.
4) Turn the small FMS Knob clockwise to ON or counterclockwise to OFF.
5) Press the FMS Knob to remove the cursor.

GPS CDI SCALING
When	GPS	is	the	 selected	 navigation	 source,	the	flight	 plan	legs	are	sequenced	 automatically	 and	
annunciations	 appear	on	the	 HSI	 for	the	 flight	 phase.	 	 Flight	phase	annunciations	 are	normally	 shown	in	
magenta, but when cautionary conditions exist the color changes to yellow.  If the current leg in the flight plan 
is	a	heading	leg,	HDG	LEG	is	annunciated	in	magenta	beneath	the	aircraft	symbol.
The	current	 GPS	CDI	scale	 setting	 is	displayed	 as	System	 CDI	on	the	 AUX	 -	System	 Setup	Page	and	the	full-
scale	 deflection	 setting	may	also	be	changed	 (2.0	nm,	1.0	nm,	 0.3	nm,	 or	Auto)	 from	this	page.		 If	the	 selected	
scaling is smaller than the automatic setting for enroute and terminal phases, the CDI is scaled accordingly 
and the selected setting is displayed rather than the flight phase ann\
unciation.
Changing the selected GPS CDI setting:
1) Use the FMS Knob to select the AUX - System Setup Page on the MFD.
2) Press the FMS Knob to activate the cursor.
3) Turn the large FMS Knob to highlight Selected in the GPS CDI box.
4) Turn the small FMS Knob to highlight the desired setting and press the ENT Key.
5) To cancel the selection, press the FMS Knob or the CLR Key.

When	 set	to	Auto	 (default),	 the	GPS	 CDI	scale	 automatically	 adjusts	to	the	 desired	 limits	based	 upon	the	
current	phase	of	flight	(Figure	2-28,	Table	2-1).

•	 Once	a	departure	procedure	is	activated,	the	CDI	is	scaled	for	departure	(0.3	nm).
•	 The	system	switches	from	departure	to	terminal CDI scaling (1.0 nm) under the following conditions:
-  The next leg in the departure procedure is not aligned with the departure runway
-	 The	 next	leg	in	the	 departure	 procedure	 is	not	 a	CA,	 CD,	 CF,	CI,	CR,	 DF,	FA,	 FC,	 FD,	 FM,	 IF,	or	TF	 (see	
Glossary for leg type definitions)
-	 After	any	leg	in	the	departure	procedure	that	is	not	a	CA	or	FA
•	 At	 30	nm	 from	 the	departure	 airport,	the	enroute phase of flight is automatically entered and CDI scaling 
changes	to	2.0	nm	over	a	distance	of	1.0	nm,	except	under	the	following	conditions:
 - When navigating with an active departure procedure, the flight phase and CDI scale does not change 
until	 the	aircraft	 arrives	at	the	 last	 departure	 waypoint	(if	more	 than	30	nm	 from	 the	departure	 airport)	or	
the leg after the last departure waypoint has been activated or a direct-to waypoint is activated.
•	 If	after	 completing	 the	departure	 procedure	 the	nearest	 airport	is	more	 than	200	nm	away	 from	the	aircraft	
and the approach procedure has not yet commenced, the CDI is scaled for oceanic	flight	(2.0	nm).
•	 Within	 31	nm	 of	the	 destination	 airport	(terminal	area),	 the	CDI	 scale	 gradually	 ramps	down	from	2.0	nm	
to 1.0 nm over a distance of 1.0 nm; except under the following conditio\
ns:
 - When navigating with an active arrival route, the flight phase and CDI scale does not change until the 
aircraft	arrives	at	the	first	waypoint	in	the	arrival	route	(if	within	31	nm	from	the	destination	airport).
•	 During	approach,	the	 CDI	 scale	 ramps	 down	even	further	 (see	Figures	 2-29	and	2-30).	 	 This	transition	
normally	 occurs	within	2.0	nm	 of	the	 final	 approach	 fix	(FAF).	 	 The	CDI	 switches	 to	approach	 scaling	
automatically once the approach procedure is activated or if Vectors-To-Final (VTF) are selected.
-	 If	the	active	 waypoint	 is	the	 FAF,	 the	ground	 track	and	the	bearing	 to	the	 FAF	 must	 be	within	 45°	of	the	
final approach segment course.
- If the active waypoint is part of the missed approach procedure, the active leg and the preceding missed 
approach legs must be aligned with the final approach segment course and the aircraft must not have 
passed the turn initiation point.

OBS MODE
 NOTE: VNV is inhibited while automatic waypoint sequencing has been suspended.
Enabling	Omni-bearing	 Selector	(OBS)	Mode	suspends	 the	automatic	 sequencing	 of	waypoints	 in	a	GPS	
flight	 plan	(GPS	 must	be	the	 selected	 navigation	 source),	but	retains	 the	current	 “active-to”	 waypoint	as	the	
navigation	 reference	even	after	passing	 the	waypoint.	 	 OBS	is	annunciated	 to	the	 lower	 right	of	the	 aircraft	
symbol	when	OBS	Mode	is	selected.
While	 OBS	Mode	 is	enabled,	 a	course	 line	is	drawn	 through	 the	Active-to	 waypoint	 on	the	 moving	 map.		If	
desired,	 the	course	 to/from	 the	waypoint	 can	now	 be	adjusted.		 When	OBS	Mode	 is	disabled,	 the	GPS	 flight	
plan	 returns	 to	normal	 operation	 with	automatic	 sequencing	 of	waypoints,	 following	the	course	 set	in	OBS	
Mode.  The flight path on the moving map retains the modified course line.

Enabling/disabling OBS Mode while navigating a GPS flight plan:
1) Press the OBS Softkey to select OBS Mode.
2) Turn a CRS Knob to select the desired course to/from the waypoint.  Press the CRS Knob to synchronize the 
Selected Course with the bearing to the next waypoint.
3) Press the OBS Softkey again to return to automatic waypoint sequencing.
As	the	 aircraft	 crosses	the	missed	 approach	 point	(MAP),	 automatic	 approach	waypoint	 sequencing	 is	
suspended.	 	 SUSP	appears	 on	the	 HSI	 at	the	 lower	 right	of	the	 aircraft	 symbol.	 	 The	OBS	Softkey	 label	
changes	 to	indicate	 the	suspension	 is	active	 as	shown	 in	figure	 2-32.		 Selecting	 the	SUSP	Softkey	 deactivates	
the	suspension	and	resumes	automatic	sequencing	of	approach	waypoints.
