2.6.2  Turn Rate Indicator
The Turn Rate Indicator is located directly above the rotating compass card. 
Tick  marks  to  the  left  and  right  of  the  lubber  line  denote  half-standard  and 
standard turn rates. A magenta Turn Rate  Trend Vector shows the current turn 
rate.  The  end  of  the  trend  vector  gives  the  heading  predicted  in  six  seconds, 
based on the present turn rate. A standard-rate turn is shown on the indicator 
by the trend vector stopping at the standard turn rate tick mark, corresponding 
to a predicted heading of 18º from the current heading. At rates greater than four 
deg/sec,  an  arrowhead  appears  at  the  end  of  the  magenta  trend  vector  and  the 
prediction is no longer valid.

2.7  Course Deviation indicator
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 CDI is not displa\
yed.

 NOTE:  The ILS Localizer and Glideslope deviation indicators will indicate 
full-scale deflection for the GNS 480 navigator at the second dot. The GNS  400W/500W series navigators will indicate full-scale deflection at the edge of the display. 
2.7.1  Changing CDI Sources
The CDI can display two sources of navigation: GPS or NAV (VOR, and LOC).  
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 coupled to GPS. When coupled to 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 coupled to GPS, the crosstrack 
error (XTK) is displayed below the white aircraft symbol.

LOC sources. 
3)  Verify the navigation source by the indication on the HSI and in the upper left 
corner of the PFD.

2.7.3  Vertical Deviation Indicator (VDI)
The  Vertical  Deviation  (Glideslope)  Indicator  (VDI)  appears  to  the  left  of 
the  VSI  whenever  an  ILS  frequency  is  tuned  in  the  active  NAV  field.  A  green 
diamond  acts  as  the  VDI  Indicator,  like  a  glideslope  needle  on  a  conventional 
indicator. If a localizer frequency is tuned and there is no glideslope signal, “NO 
GS”  is  annunciated.  The  glideslope  on  an  ILS  approach  is  only  shown  if  the 
current heading is within 90° of the selected course. This prevents the glideslope 
from being displayed during localizer backcourse approaches. 
Vertical Deviation Source
Vertical Deviation Indicator
Figure 2-31  Vertical Deviation Indicator (ILS Source)
The  vertical  deviation  is  similar  to  the  glideslope  for  GPS  approaches 
supporting WAAS vertical guidance (LNAV+V, L/VNAV , LPV). When an approach 
of  this  type  is  loaded  into  the  flight  plan  and  GPS  is  the  selected  navigation 
source,  the  Vertical  Deviation  Indicator  appears  as  a  magenta  diamond.  If  the 
approach  type  downgrades  to  LNAV  past  the  final  approach  fix  (FAF),  or  the 
approach only supports LNAV service, “NO GP” is annunciated.

2.7.4  Auto-Slewing
The G500 system is designed to interface with GNS navigator units and also 
manage  up  to  four  different  CDI  course  pointers  (GPS1,  NAV1,  GPS2,  NAV2) 
independently. The G500 will automatically slew the NAV course pointer to the 
correct final approach course when a ILS, LOC, LOC BC, LDA or SDF approach 
is  active  in  the  GNS  navigator  and  the  appropriate  frequency  is  in  the  active 
window in the navigator. The G500 will Auto-Slew the HSI course pointer for an 
ILS, LOC, LOC BC, LDA, or SDF approach when the steps below are completed 
in the following order: 
1)   The  desired  approach  is  selected  and  activated  in  the  navigator  (this  can  be 
verified by the approach waypoints appearing on the GDU620 MFD Nav Map 
Page or FPL Page). 
2)   The appropriate frequency is the active frequency in the navigator. 
3)   The  CDI  selection  on  the  GDU  620  is  changed  to  NAV  course  pointer  for  the 
active navigator. 
 NOTE: If the NAV course pointer is displayed for the active navigator 
when the approach is activated and the localizer frequency is tuned, the pilot will need to switch to another CDI source and then back to NAV for the course pointer to Auto-Slew.   
For example, if NAV1 is currently selected, the pilot must:   press the CDI soft key twice: NAV1>GPS1>NAV1 OR press the 1-2 soft key twice: NAV1>NAV2>NAV1
 NOTE:  For LOC BC approaches, the course pointer will slew 180 degrees from the inbound course.

Example of activating Auto-Slewing in the G500: 
Course Pointer slewed to 218° for the ILS 
     
Figure 2-33  Auto-Slewing HSI with ILS Loaded and Shown with the Corresponding  
Approach Plate
1) The  aircraft  is  flying  vectors  to  final  on  an  active  ILS  approach,  with  the 
appropriate approach in the GNS navigator. 
2)  The appropriate ILS frequency must be activate in the navigator. 
3)  Verify that the waypoints for the approach are displayed on the Nav Map Page 
or the FPL Page of the MFD. 
4)  Upon approaching the final course, select LOC on the HSI. 
 NOTE:  If auto CDI switching is active on the GNS unit, the GNS will force 
the GNS/GDU 620 to NAV when the aircraft is close to the LOC course. 
5)  The CDI and course pointer will change from magenta to green and the pointer 
will move, or slew, to the final approach course (or 180° from the final approach 
course for LOC BC approaches).

2.8 Supplemental Flight Data
2.8.1  Bearing Pointers
Two Bearing Pointers can be displayed on the HSI for NAV and GPS sources. 
The pointers are light blue and are single- (BRG1) or double-lined (BRG2); an 
icon  is  shown  in  the  respective  information  window  to  indicate  the  pointer 
type. The system must be configured for a second navigation source to show the 
BRG2 selection. 
When  a  Bearing  Pointer  is  displayed,  its  associated  information  window  is 
also displayed. 
The Bearing Information windows are displayed to the lower sides of the HSI 
and show: 
•	 Bearing	source	(GPS,	NAV,	or	ADF)
•	 Pointer	icon	(BRG1	=	single	line,	BRG2	=	double	line)
The Bearing Pointer is removed from the HSI if: 
•	 The	NAV	radio	is	not	receiving	the	tuned	VOR station
•	 The	NAV	radio	is	tuned	to	a	Localizer frequency

2.8.2  Temperature Display
The Outside Air Temperature (OAT) is displayed to the left of the HSI. The 
O AT  can be displayed in ºF or ºC, which is configured in the Aux System Setup 
Page.  The  temperature  is  derived  from  the  Temperature  Probe  on  the  aircraft. 
The displayed temperature is the Static Air Temperature reported by the Air Data 
Computer . This temperature value is corrected for ram air heating effects.
