6.6 TERRAIN-SVS
 WARNING: Do not use Terrain-SVS information for primary terrain avoidance.  Terrain-SVS is intended only 
to enhance situational awareness.
 NOTE: Terrain data is not displayed if the aircraft is outside of the terrain d\
atabase coverage area.
 NOTE:  Terrain-SVS is standard when the Synthetic Vision System (SVS) option is installed.  The TAWS-B 
option will take precedence over the Terrain-SVS and Terrain Proximity features.
G1000	 Terrain-SVS	 is	a	terrain	 awareness	 system	available	 with	the	Synthetic	 Vision	System	 (SVS).	 	 SVS	
functionality	 is	offered	 as	an	 optional	 enhancement.		 Optional	Terrain	Awareness	 and	Warning	 System	-	Class	 B	
(TAWS-B)	 or	standard	 Terrain-SVS	 is	integrated	 within	SVS	to	provide	 visual	and	auditory	 alerts	to	indicate	 the	
presence	 of	threatening	 terrain	relevant	 to	the	 projected	 flight	path.		 For	detailed	 information	 regarding	SVS,	refer	
to	the	Synthetic	Vision	System	(SVS)	section	of	the	G1000	Pilot’s	Guide.
Terrain-SVS	 does	not	comply	 with	TSO-C151b	 certification	standards.		It	increases	 situational	 awareness	and	
aids	in	reducing	 controlled	 flight	into	terrain	 (CFIT).	 	 Do	not	 confuse	 Terrain-SVS	 with	Terrain	 Awareness	 and	
Warning	System	(TAWS).		 TAWS	is	more	 sophisticated	 and	robust,	 and	it	is	 TSO-C151b	 certified.		Although	the	
terrain	and	obstacle	 color	map	displays	 are	the	 same,	 TAWS	 uses	more	 sophisticated	 algorithms	to	assess	 aircraft	
distance	from	terrain	and	obstacles.
Terrain-SVS	does	not	provide	the	following:
•	 Premature	Descent	Alerting	(PDA)
•	 Excessive	Descent	Rate	(EDR)
•	 Negative	Climb	Rate	(NCR)
•	 Descent	to	500	Feet	Callout	(DFC)
Terrain-SVS	requires	the	following	components	to	operate	properly:
•	 Valid	3-D	GPS	position
•	 Valid	terrain/obstacle	database
Terrain-SVS	 displays	altitudes	 of	terrain	 and	obstructions	 relative	to	the	 aircraft	 position	 and	altitude	 with	
reference	 to	a	database	 that	may	 contain	 inaccuracies.		 Terrain	and	obstructions	 are	shown	 only	if	they	 are	in	the	
database.		 Terrain	and	obstacle	 information	 should	be	used	 as	an	 aid	 to	situational	 awareness.		 They	should	 never	
be	used	to	navigate	or	maneuver	around	terrain.
Note	that	all	obstructions	 may	not	be	available	 in	the	 terrain	 and	obstacle	 database.	 	 No	terrain	 and	obstacle	
information	is	shown	without	a	valid	3-D	GPS	position.
The	 G1000	 GPS	receiver	 provides	 the	horizontal	 position	and	altitude.	 	 GPS	altitude	 is	derived	 from	satellite	
position.		 GPS	altitude	 is	then	 converted	 to	the	 height	 above	geodetic	 sea	level	 (GSL),	 which	 is	the	 height	 above	
mean	sea	level	 calculated	 geometrically.		 GSL	altitude	 is	used	 to	determine	 terrain	and	obstacle	 proximity.		 GSL	
altitude	accuracy	 is	affected	 by	satellite	 geometry,	 but	is	not	 subject	 to	variations	 in	pressure	 and	temperature	 that	
normally	affect	pressure	 altitude	sensors.		 GSL	altitude	 does	not	require	 local	altimeter	 settings	to	determine	 MSL	
altitude.		It	is	a	widely-used	MSL	altitude	source.  
						

							Garmin G1000 Pilot’s Guide for the Socata TBM 850190-00709-04  Rev. A410
HAZARD AVOIDANCE
Terrain	and	obstacle	 databases	 are	referenced	 to	GSL.	 	 Using	 the	GPS	 position	 and	altitude,	 the	Terrain-SVS	
feature	portrays	a	3-D	picture	of	the	surrounding	terrain	and	obstacles	relative	to	the	position	and	altitude	of	the	
aircraft.	 	 GPS	position	 and	GSL	 altitude	 are	used	 to	calculate	 and	predict	 the	aircraft’s	 flight	path	in	relation	 to	
the	surrounding	 terrain	and	obstacles.		 In	this	 way,	 the	pilot	 can	view	 predicted	 dangerous	 terrain	and	obstacle	
conditions.
DISPLAYING TERRAIN-SVS DATA
Terrain-SVS	 uses	yellow	 (caution)	 and	red	(warning)	 to	depict	 terrain	 and	obstacles	 with	heights	 greater	than	
200	feet	above	 ground	 level,	AGL.		 Alerts	 are	given	 relative	 to	aircraft	 altitude.		 Colors	are	adjusted	 automatically	
as	the	 aircraft	 altitude	 changes.	 	 The	colors	 and	symbols	 shown	in	the	 figure	 and	table	 below	 are	used	 to	
represent	terrain,	obstacles,	and	potential	impact	points.

The	Map	 -	Terrain-SVS	 Page	is	the	 principal	 page	for	viewing	 terrain	and	obstacle	 information.		 In	addition,	
Terrain-SVS	information	can	be	displayed	on	the	following	pages	and	maps	for	reference:
•	 PFD
Displaying terrain and obstacle information (maps other than the Terrain-SVS Page):
1) Select the MAP Softkey (for the PFD Inset Map, select the INSET Softkey).
2) Select the TERRAIN Softkey to display terrain and obstacle data.
When	 Terrain-SVS	 is	selected	 on	maps	 other	than	the	Terrain-SVS	 Page,	an	icon	 to	indicate	 the	feature	 is	
enabled	 for	display	 and	a	legend	 for	Terrain-SVS	 terrain	colors	is	shown.	 	 An	annunciation	 window	appears	
below	the	legend.
The	Navigation	 Map	Page	 Setup	 Menu	 provides	 a	means	 in	addition	 to	the	 softkey	 for	enabling/disabling	
display	 of	terrain	 and	obstacles.		 The	setup	 menu	 also	controls	 the	map	 range	 settings	 above	which	 terrain	 and	
obstacle	 data	are	decluttered	 from	the	display.		 If	a	map	 range	 larger	 than	the	map	 range	 setting	 is	selected,	 the	
data	is	removed	 from	the	map.			 For	terrain	 data,	the	enable/disable	 function	applies	only	to	the	 MFD,	 while	the	
range	setting	also	affects	the	PFD	Inset	Map.
Terrain	 data	can	be	selected	 for	display	 independently	 of	obstacle	 data;	however,	 obstacles	for	which	 warnings	
and cautions are issued are shown when terrain is selected for display and the map range is within\
 the setting 
limit.
Maps	other	than	the	Terrain-SVS	 Page	use	settings	 based	on	those	 selected	 for	the	 Navigation	 Map	Page.		 The	
maximum	 display	ranges	for	obstacles	 on	each	 map	are	dependent	 on	the	 range	 setting	 made	for	the	 Navigation	
Map.		 If	the	 maximum	 range	for	obstacle	 display	on	the	 Navigation	 Map	is	adjusted	 to	below	 20	nm,	 the	highest	
obstacle	display	range	settings	on	the	other	applicable	maps	are	also	adjusted	proportionally.
Customizing terrain and obstacle display on the Navigation Map Page:
1) Select the Navigation Map Page.
2) Press the MENU Key.
3) With Map Setup highlighted, press the ENT Key (Figure 6-128).
4) Turn the small FMS Knob to select the Map Group and press the ENT Key (Figure 6-129)
