OVERSPEED PROTECTION
 NOTE: Overspeed protection is not active in Altitude Hold, Glideslope or Glidepath modes.
While	Pitch	Hold,	 Vertical	 Speed,	Flight	Level	Change,	 Vertical	Path	Tracking,	 or	an	 altitude	 capture	mode	is	
active,	 airspeed	 is	monitored	 by	the	 flight	 director.		 Pitch	commands	 are	not	 changed	 until	overspeed	 protection	
becomes active.  Overspeed protection is provided in situations where the flight director cannot acquire and 
maintain	the	mode	 reference	 for	the	 selected	 vertical	mode	without	 exceeding	 the	certified	 maximum	 autopilot	
airspeed.
When	an	autopilot	 overspeed	 condition	occurs,	the	Airspeed	 Reference	 appears	in	a	box	 above	 the	Airspeed	
Indicator,	 flashing	a	yellow	 ‘MAXSPD’	 annunciation.		 Engine	power	should	 be	reduced	 and/or	the	pitch	 reference	
adjusted to slow the aircraft.  The annunciation disappears when the overspeed condition is resolved.

8.1 SYNTHETIC VISION SYSTEM (SVS)
 WARNING: Use appropriate primary systems for navigation, and for terrain, obstacle, and traffic avoidance.  
SVS is intended as an aid to situational awareness only and may not provide either  the accuracy or reliability 
upon which to solely base decisions and/or plan maneuvers to avoid terra\
in, obstacles, or traffic.
The optional Synthetic	 Vision	System	 (SVS)	is	a	visual	 enhancement	 to	the	 G1000	 Integrated	 Flight	Deck.		 SVS	
depicts	 a	forward-looking	 attitude	display	of	the	 topography	 immediately	 in	front	 of	the	 aircraft.	 	 The	field	 of	
view	is	30	 degrees	 to	the	 left	and	 35	degrees	 to	the	 right.		 SVS	information	 is	shown	 on	the	 Primary	 Flight	Display	
(PFD),	 or	on	 the	 Multifunction	 Display	(MFD)	in	Reversionary	 Mode	(Figure	 8-105).	 	 The	depicted	 imagery	is	
derived	from	the	aircraft	 attitude,	 heading,	 GPS	three-dimensional	 position,	and	a	nine	 arc-second	 database	of	
terrain,	obstacles,	 and	other	 relevant	 features.	 	 The	terrain	 data	resolution	 of	nine	 arc-seconds,	 meaning	that	
the	terrain	 elevation	 contours	are	stored	 in	squares	 measuring	 nine	arc-seconds	 on	each	 side,	 is	required	 for	the	
operation	 of	SVS.		 Loss	of	any	 of	the	 required	 data,	including	 temporary	 loss	of	the	 GPS	 signal,	 will	cause	 SVS	to	
be	disabled	until	the	required	data	is	restored.
The	SVS	 terrain	 display	 shows	land	contours	 (colors	are	consistent	 with	those	 of	the	 topographical	 map	display),	
large	 water	 features,	 towers,	and	other	 obstacles	 over	200’	 AGL	 that	are	included	 in	the	 obstacle	 database.		 Cultural	
features	on	the	 ground	 such	as	roads,	 highways,	 railroad	tracks,	cities,	and	state	 boundaries	 are	not	 displayed	
even	 if	those	 features	 are	found	 on	the	 MFD	 map.		 The	terrain	 display	 also	includes	 a	north–south	 east–west	grid	
with lines oriented with true north and spaced at one arc-minute intervals to assist in orientation relative to the 
terrain.
The	optional	 Terrain	Awareness	 and	Warning	 System	(TAWS)	 or	standard	 Terrain-SVS	 is	integrated	 within	
SVS	to	provide	 visual	and	auditory	 alerts	to	indicate	 the	presence	 of	terrain	 and	obstacle	 threats	relevant	 to	the	
projected	flight	path.		Terrain	alerts	are	displayed	in	red	and	yellow	shading	on	the	PFD.
The	 terrain	 display	 is	intended	 for	situational	 awareness	only.	 	It	may	 not	provide	 the	accuracy	 or	fidelity	 on	
which	to	base	 decisions	 and	plan	 maneuvers	 to	avoid	 terrain	 or	obstacles.	 	 Navigation	 must	not	be	predicated	
solely	upon	the	use	of	the	Terrain–SVS	or	TAWS	terrain	or	obstacle	data	displayed	by	the	SVS.
The	following	SVS	enhancements	appear	on	the	PFD:
•	 Pathways
•	 Flight

SVS OPERATION
SVS	is	activated	 from	the	PFD	 using	 the	softkeys	 located	along	the	bottom	 edge	of	the	 display.		 Pressing	 the	
softkeys	turns	the	related	 function	 on	or	off.		 When	 SVS	is	enabled,	 the	pitch	 scale	increments	 are	reduced	 to	
10	degrees	up	and	7.5	degrees	down.
SVS	functions	 are	displayed	 on	three	 levels	 of	softkeys.		 The	PFD Softkey	leads	into	the	PFD	 function	 Softkeys,	
including	 synthetic	vision.		Pressing	 the	SYN VIS	Softkey	 displays	 the	SVS	 feature	 softkeys.		 The	softkeys	 are	
labeled	PATHWAY,	SYN TERR, HRZN HDG,	and	APTSIGNS.	 	 The	BACK Softkey	 returns	to	the	 previous	
level	of	softkeys.		Synthetic	Terrain	must	be	active	before	any	other	SVS	feature	may	be	activated.
HRZN HDG,	APTSIGNS,	and	PATHWAY	Softkeys	 are	only	 available	 when	the	SYN TERR	Softkey	 is	
activated	 (gray	with	black	 characters).		 After	activating	 the	SYN TERR	Softkey,	 the	HRZN HDG,	APTSIGNS,	
and PATHWAY	softkeys	 may	be	activated	 in	any	 combination	 to	display	 desired	 features.		 When	system	 power	
is	cycled,	 the	last	 selected	 state	(on	or	off)	 of	the	SYN TERR, HRZN HDG,	APTSIGNS,	and	PATHWAY 
softkeys	is	remembered	by	the	system.
•	PATHWAY	Softkey	enables	display	of	rectangular	boxes	that	represent	course	guidance.
•	SYN TERR	Softkey	enables	synthetic	terrain	depiction.
•	HRZN HDG	Softkey	enables	horizon	heading	marks	and	digits.
•	APTSIGNS	Softkey	enables	airport	signposts.

PATHWAYS
Pathways	 provide	a	three-dimensional	 perspective	view	of	the	 selected	 route	of	flight	 shown	 as	colored	 rectangular 	
boxes	representing	 the	horizontal	 and	vertical	 flight	path	of	the	 active	 flight	plan.		 The	box	size	represents	 700	feet	
wide	 by	200	 feet	tall	during	 enroute,	 oceanic,	and	terminal	 flight	phases.		 During	an	approach,	 the	box	 width	 is	
700	 feet	or	one	 half	 full	scale	 deviation	 on	the	 HSI,	 whichever	 is	less.		 The	height	 is	200	 feet	or	one	 half	 full	scale 	
deviation	 on	the	 VDI,	 whichever	 is	less.		 The	altitude	 at	which	 the	pathway	 boxes	are	displayed	 is	determined	 by	
the	 selected	 altitude	during	climb,	cruise,	 and	when	 the	active	 leg	is	the	 final	 approach	 course	prior	to	intercepting 	
the	glidepath/glideslope.		 During	a	descent	 (except	while	on	the	 approach	 glidepath/glideslope),	 the	pathway	 boxes	
are	displayed	 at	the	 selected	 altitude,	 or	the	 VNAV	 altitude	 programmed	 for	the	 active	 leg	in	the	 flight	 plan,	or	the 	
published	 altitude	constraint,	 whichever	is	higher	 (Figure	 8-4).		Just	prior	 to	intercepting	 the	glidepath/glideslope, 	
the	pathway	boxes	are	displayed	on	the	glidepath/glideslope,	or	the	selected	altitude,	whichever	is	lower.
The	color	 of	the	 rectangular	 boxes	may	be	magenta,	 green,	or	white	 depending	 on	the	 route	 of	flight	 and	
navigation	 source	selected.	 	 The	active	 GPS	or	GPS	 overlay	 flight	plan	leg	is	represented	 by	magenta	 boxes	that	
correspond	 to	the	 Magenta	 CDI.		A	localizer	 course	is	represented	 by	green	 boxes	 that	correspond	 to	a	green	 CDI.		
An	inactive	 leg	of	an	 active	 flight	plan	is	represented	 by	white	 boxes	 corresponding	 to	a	white	 line	drawn	 on	the	
Inset	map	or	MFD	map	indicating	an	inactive	leg.

Pathways	 provide	supplemental	 glidepath	information	 on	an	active	 ILS,	LPV,	 LNAV/VNAV,	 and	some	 LNAV	
approaches.		 Pathways	are	intended	 as	an	 aid	 to	situational	 awareness	and	should	 not	be	used	 independent	
of	the	 CDI,	 VDI,	glide	 path	indicator,	 and	glide	 slope	 indicator.	 	 They	are	removed	 from	the	display	 when	
the	selected	 navigation	 information	 is	not	 available.		 Pathways	are	not	 displayed	 beyond	the	active	 leg	when	
leg	 sequencing	 is	suspended	 and	are	not	 displayed	 on	any	 portion	 of	the	 flight	 plan	leg	that	 would	 lead	to	
intercepting	a	leg	in	the	wrong	direction.
DePaR tURe anD enROUte
Prior	 to	intercepting	 an	active	 flight	plan	leg,	pathways	 are	displayed	 as	a	series	 of	boxes	 with	pointers	 at	
each	corner	 that	point	 in	the	 direction	 of	the	 active	 waypoint.		 Pathways	are	not	 displayed	 for	the	 first	 leg	
of	the	 flight	 plan	if	that	 segment	 is	a	Heading-to-Altitude	 leg.		The	first	 segment	 displaying	 pathways	is	the	
first	 active	 GPS	leg	or	active	 leg	with	 a	GPS	 overlay.		 If	this	 leg	of	the	 flight	 plan	route	 is	outside	 the	SVS	
field	 of	view,	 pathways	 will	not	be	visible	 until	the	aircraft	 has	turned	 toward	 this	leg.		 While	 approaching	
the	center	 of	the	 active	 leg	and	 prescribed	 altitude,	the	number	 of	pathway	 boxes	decreases	 to	a	minimum	
of	four.
Pathways	 are	displayed	 along	the	flight	 plan	route	 at	the	 highest	 of	either	 the	selected	 altitude	or	the	
programmed	 altitude	for	the	 leg.		 Climb	 profiles	 cannot	be	displayed	 due	to	the	 variables	 associated	 with	
aircraft	performance.		 Flight	plan	legs	requiring	 a	climb	 are	indicated	 by	pathways	 displayed	 at	a	level	 above	
the	aircraft	at	the	altitude	selected	or	programmed.

Descent anD aPPRO ach
Pathways	 are	shown	 descending	 only	for	a	programmed	 descent	(Figures	 8-5,	8-6).		 When	 the	flight	 plan	
includes	 programmed	 descent	segments,	 pathways	are	displayed	 along	the	descent	 path	provided	 that	the	
selected	altitude	is	lower	than	the	programmed	altitude.
When	 an	approach	 providing	 vertical	guidance	 is	activated,	 Pathways	are	shown	 level	at	the	 selected	
altitude up to the point along the final approach course where the altitude intercepts the extended vertical 
descent	 path,	glidepath,	 or	glideslope.	 	 From	the	vertical	 path	descent,	 glidepath,	 or	glideslope	 intercept	
point,	the	pathways	 are	shown	 inbound	 to	the	 Missed	 Approach	 Point	(MAP)	 along	the	published	 lateral	
and	vertical	descent	path,	or	at	the	selected	altitude,	whichever	is	lower.
During	an	ILS	 approach,	 the	initial	 approach	 segment	is	displayed	 in	magenta	 at	the	 segment	 altitudes	
if	GPS	 is	selected	 as	the	 navigation	 source	on	the	 CDI.	 	 When	 switching	 to	localizer	 inbound	 with	LOC	
selected	 as	the	 navigation	 source	on	the	 CDI,	 pathways	 are	displayed	 in	green	 along	the	localizer	 and	glide	
slope.
VOR,	 LOC	BC,	and	 ADF	 approach	 segments	that	are	approved	 to	be	 flown	 using	GPS	are	displayed	 in
