AUTO-TUNING NAV FREQUENCIES ON APPROACH ACTIVATION
 NOTE:  The primary NAV frequency is auto-tuned upon loading a VOR or ILS/Localizer approach.
 NOTE:  When an ILS/LOC approach has been activated in GPS Mode, the system switches to NAV Mode as 
the final approach course is intercepted (within 15 nm of the FAF).  See the Flight Management Section for 
details.
NAV	 frequencies	 are	automatically	 loaded	into	the	NAV	 Frequency	 Box	on	approach	 activation,	 on	both	 PFD1	
and	PFD2.
When	 loading	 or	activating	 a	VOR	 or	ILS/LOC	 approach,	 the	approach	 frequency	 is	automatically	 transferred	
to	a	NAV	frequency	field	as	follows:
•	 If	the	current	 CDI	navigation	 source	is	GPS,	 the	approach	 frequency	 is	transferred	 to	the	 NAV1	 or	NAV2	
active	 frequency	 fields.		The	frequency	 that	was	previously	 in	the	 NAV1	 or	NAV2	 active	frequency	 fields	are	
transferred to standby.
•	 If	the	current	 CDI	navigation	 source	is	GPS,	 and	if	the	 approach	 frequency	 is	already	 loaded	into	the	NAV1	
or	NAV2	standby	frequency	field,	the	standby	frequency	is	transferred	to	active.
•	 If	 the	current	 CDI	navigation	 source	is	NAV1	 or	NAV2,	 the	approach	 frequency	 is	transferred	 to	the	 standby	
frequency	fields	of	the	selected	CDI	NAV	radio.

MARKER BEACON RECEIVER
 NOTE:  The marker beacon indicators operate independently of marker beacon audio and cannot be turned 
off.
The	 marker	 beacon	receiver	 is	used	 as	part	 of	the	 ILS.		 The	marker	 beacon	receiver	 is	always	 on	and	 detects	
any marker beacon signals within the reception range of the aircraft.
The receiver detects the three marker tones – outer, middle, and inner – and provides the marker beacon 
annunciations	located	to	the	left	of	the	Altimeter	on	the	PFD.

Indication Middle Marker 
Indication Inner Marker 
Indication
Figure 4-28  Marker Beacon Keys
The	 Audio	 Panels	 provide	 three	different	 states	of	marker	 beacon	operation;	 On,	Muted,	 and	Deselected.		
Pressing the MKR/MUTE Key selects and deselects marker beacon audio.  The key annunciator ind\
icates when 
marker beacon audio is selected.
During	 marker	 beacon	audio	reception,	 pressing	the	MKR/MUTE Key mutes the audio but does not affect the 
marker	annunciations	 (Figure	4-27).		The	marker	 tone	is	silenced,	 then	waits	 for	the	 next	 marker	 tone.		The	
MKR/MUTE	Key	 Annunciator	 is	illuminated,	 indicating	audio	muting.		 The	audio	 returns	 when	the	next	 marker	
beacon	 signal	is	received.		 If	the	MKR/MUTE	Key	 is	pressed	 during	signal	reception	 (O,	M,	I	indication)	 while	
marker beacon audio is muted, the audio is deselected and the MKR/MUTE	Key	Annunciator	is	extinguished.
Pressing the HI SENS Key switches between high and low marker beacon receiver sensitivity.  The HI	SENS	
function (annunciator illuminated) is used to provide an earlier indication when nearing a marker during an 
approach.  The LO	SENS	function	(annunciator	 extinguished)	 results	in	a	narrower	 marker	dwell	while	over	a	
station.

ADF/DME TUNING
 NOTE:  When another auxiliary window is turned on, the ADF/DME Tuning Window is replaced on the PFD.
See	 the	Flight	 Instruments	 Section	for	displaying	 the	DME	 and	bearing	 information	 windows	(ADF)	and	
using	the	ADF	as	the	source	for	the	bearing	pointer.
The	G1000	 system	tunes	the	ADF	 receiver	 (optional)	 and	DME	 transceiver	 (optional).		 The	ADF	 is	tuned	 by	
entering	 the	frequency	 in	the	 ADF	 standby	 frequency	 field	of	the	 ADF/DME	 Tuning	Window.		 (The	softkey	 may	
be labeled ADF/DME, ADF, or DME, depending on installed equipment.)
The	UHF	 DME	 frequency	 is	tuned	 by	pairing	 with	a	VHF	 NAV	 frequency.		 DME	frequency	 pairing	is	automatic	
and	only	the	VHF	NAV	frequency	is	shown.
The	following	ADF/DME	information	is	displayed	in	the	ADF/DME	Tuning	Window:
•	Active and standby	ADF	frequencies
•	ADF	receiver	mode
•	ADF	receiver	volume
•	DME	tuning	mode	(DME	transceiver	pairing)
When	 the	ADF/DME	 Tuning	Window	 is	displayed,	 the	selection	 cursor	is	placed	 over	the	standby	 ADF	
frequency	field.
Turning the large FMS	Knob	 moves	 the	selection	 cursor	through	 the	various	 fields	(standby	 ADF	frequency,	
ADF	receiver	 mode,	ADF	radio	volume,	and	 DME	tuning	 mode).		 Pressing	the	FMS Knob activates/deactivates 
the	selection	 cursor	in	the	 ADF/DME	 Tuning	Window.		 The	ADF	 frequency	 is	entered	 using	the	FMS Knob and 
the ENT Key.
