6.4 STORMSCOPE
 NOTE:   The L-3 STORMSCOPE® WX-500 Lightning detection system is not intended for hazardous 
thunderstorm penetration.  Weather information on the G1000 MFD is approved for weather avoidance 
only.  Refer to the WX-500 User’s Guide for a detailed description of Stormscope operation.
 NOTE:  Stormscope lightning data cannot be displayed at the same time as XM WX lightning data or GFDS  
lightning data.
The	following	pages	can	display	Stormscope	data:
•	 PFD	Inset	Map•	 AUX	-	Trip	Planning	Page
•	 Stormscope	Page•	 Nearest	Pages
•	 Navigation	Map
The	 Map	 -	Stormscope	 Page	is	the	 principal	 page	for	viewing	 Stormscope	 data.		Stormscope	 data	can	be	displayed	
on other map pages as an additional reference. To display Stormscope	 data	on	any	 map	 besides	 the	Stormscope	
Page,	 select	 the	MAP	Softkey	 (or	the	INSET	Softkey	 for	the	 PFD	 Inset	 Map),	 then	select	 the	STRMSCP	Softkey.		
These	 pages	can	also	 display	 cell	or	strike	 data	using	 the	yellow	 lightning	 strike	symbology	 shown	in	Table	 6-12.

The	following	Stormscope	options	are	available	(Figure	6-115):
•	STRMSCP LTNG	–	Turns	the	display	of	Stormscope	data	on	or	off.	
•	STRMSCP MODE	–	 Selects	 the	CELL	 or	STRIKE	 mode	of	lightning	 activity.		Cell	mode	 identifies	 clusters	or	
cells	of	electrical	activity.		Strike	mode	indicates	the	approximate	location	of	lightning	strikes.	
•	STRMSCP SMBL	–	 Selects	 the	range	 at	which	 Stormscope	 data	displays.		 Stormscope	 data	is	removed	 when	
a	map	range	greater	than	the	STRMSCP	SMBL	value	is	selected.

CELL AND STRIKE MODE ON THE NAVIGATION MAP
On	the	Navigation	 Map,	cell	mode	 identifies	 cells	of	lightning	 activity	(Figure	 6-116).		 Stormscope	 identifies	
clusters	of	electrical	 activity	that	indicate	 cells.		Strike	 mode	indicates	 the	approximate	 location	of	lightning	
strikes.	
Selecting the ‘cell’ or ‘strike’ mode on the Navigation Map:
1) Press the MENU Key.
2) With ‘Map Setup’ selected, press the ENT Key. 
3) Select the ‘Weather’ group.  
4) Press the ENT Key.  The cursor flashes on ‘STRMSCP LTNG’. 
5) Turn the large FMS Knob to select ‘STRMSCP MODE’.
6) Turn the small FMS Knob to change between ‘CELL’ and ‘STRIKE’ options.  When an item is selected, press the 
ENT Key.

ZOOM RANGE ON THE NAVIGATION MAP
Stormscope	lightning	data	can	be	displayed	 up	to	800	 nm	zoom	 range	(in	North	 Up	orientation)	 on	the	
Navigation	 Map	Page.		However,	 in	Track	 Up	orientation	 at	the	 500	 nm	range,	 a	portion	 of	Stormscope	 lightning	
data	can	be	behind	 the	aircraft	 and	therefore	 not	visible	 on	the	 Navigation	 Map.		Since	 the	range	 for	Stormscope	
data	 is	400	 nm	diameter	 total	(200	 nm	in	front	 and	200	 nm	behind),	 the	500	 nm	range	 in	North	 Up	orientation	
shows all the data. 
At	a	map	range	of	less	than	25	nm,	Stormscope	lightning	data	is	not	displayed,	but	can	still	be	present.
The	 maximum	 zoom	range	can	also	 be	set	 on	the	 Navigation	 Map.		Note	that	Stormscope	 data	above	 the	
selected	maximum	zoom	range	is	decluttered.	
Selecting a Stormscope range on the Navigation Map:
1) Press the MENU Key.
2) Select ‘MAP SETUP’.
3) Select the ‘Weather’ group.  
4) Press the ENT Key.  
5) Turn the large FMS Knob to select ‘STRMSCP SMBL’.  
6) Turn the small FMS Knob to select the maximum display range.  
7) Press the ENT Key.

6.5 TERRAIN PROXIMITY
 WARNING: Do not use Terrain Proximity information for primary terrain avoidance.  Terrain Proximity is 
intended only to enhance situational awareness.
 NOTE: Terrain data is not displayed when the aircraft is outside of the terrain\
 database coverage area.
 NOTE: Terrain Proximity is disabled when the Terrain-SVS or TAWS-B options are installed.
G1000	Terrain	 Proximity	 is	a	terrain	 awareness	 system	that	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	Proximity	 with	Terrain	 Awareness	 and	Warning	 System	(TAWS).	 	 TAWS	is	more	 sophisticated	
and	robust,	 and	it	is	 TSO-C151b	 certified.		Terrain	Proximity	 does	not	provide	 warning		 annunciations	 or	voice	
alerts.		 It	only	 provides	 color	indications	 on	map	 displays	 when	terrain	 and	obstacles	 are	within	 a	certain	 altitude	
threshold	 from	the	aircraft.		 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	Proximity	requires	the	following	components	to	operate	properly:
•	 Valid	3-D	GPS	position
•	 Valid	terrain/obstacle	database
Terrain	 Proximity	 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.
Terrain	and	obstacle	 databases	 are	referenced	 to	GSL.		 Using	 the	GPS	 position	 and	altitude,	 the	Terrain	 Proximity	
feature	portrays	a	2-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 PROXIMITY DATA
The	Map	 -	Terrain	 Proximity	 Page	is	the	 principal	 page	for	viewing	 terrain	and	obstacle	 information.	 The	
symbols	and	colors	 in	the	 figure	 and	table	 below	 are	used	 to	represent	 obstacles	and	aircraft	 altitude		 when	the	
Terrain	 Proximity	 Page	is	selected	 for	display.		 Terrain	Proximity	 uses	black,	 yellow,	 and	red	to	represent	 terrain	
information	 relative	to	aircraft	 altitude.		 The	color	 of	each	 obstacle	 is	associated	 with	the	altitude	 of	the	 aircraft.

Table 6-13  Terrain Proximity Terrain/Obstacle Colors and Symbology
Terrain	and	obstacle	information	can	be	displayed	on	the	following	pages:
•	 PFD
Displaying terrain and obstacle information (maps other than the Terrain Proximity 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	 Proximity	 is	selected	 on	maps	 other	than	the	Terrain	 Proximity	 Page,	an	icon	 to	indicate	 the	
feature	is	enabled	for	display	and	a	legend	for	Terrain	Proximity	colors	are	shown	(Figure	6-124).
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.

Terrain	data	can	be	selected	 for	display	 independently	 of	obstacle	 data;	however,	 obstacles	recognized	 by	
Terrain	Proximity	 as	yellow	 or	red	 are	shown	 when	terrain	 is	selected	 for	display	 and	the	map	 range	 is	within	
the setting limit.
Maps	 besides	 the	Terrain	 Proximity	 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 6-121).
4) Turn the small FMS Knob to select the ‘Map’ Group and press the ENT Key (Figure 6-122).
