FLYING A FLIGHT PLAN/GPS COURSE
 NOTE: Changing the navigation source cancels Navigation Mode and causes the fl\
ight director to revert 
back to Roll Hold Mode (wings rolled level).
As	the	 aircraft	 closes	on	Salina	 VOR,	GPS	is	used	 to	navigate	 the	next	 leg,	airway	 V244.	 	 The	aircraft	 is	
currently	tracking	inbound	on	Airway	V4.
Flying a GPS flight plan:
1) Transition from VOR to GPS Navigation Mode:
a) Press the CDI Softkey until GPS is the selected navigation source.
b) Press the NAV Key to activate GPS Navigation Mode.  The autopilot guides the aircraft along the active flight 
plan leg.
2) Following the flight plan, the autopilot continues to steer the aircraft under GPS guidance.  Note that in GPS 
Navigation Mode, course changes defined by the flight plan are automatically made wi\
thout pilot action 
required.

DESCENT
While	flying	the	arrival	 procedure,	 the	aircraft	 is	cleared	 for	descent	 in	preparation	 for	the	 approach	 to	KCOS.		
Three methods are presented for descent:
•	 Flight	 Level	Change	 descent	–	Flight	 Level	Change	 Mode	can	be	used	 to	descend	 to	the	 Selected	 Altitude	at	a	
constant airspeed.  This descent method does not account for flight pl\
an waypoint altitude constraints.
•	 Vertical	 Path	Tracking	 descent	–	Vertical	 Path	Tracking	 Mode	is	used	 to	follow	 the	vertical	 descent	 path	
defined	in	the	 GPS	 flight	 plan.		 Altitude	 constraints	 correspond	 to	waypoints	 in	the	 flight	 plan.		 Before	 VNV	
flight control can provide vertical profile guidance, a VNV flight plan must be entered and enabled.
•	 Non-path	 descent	in	a	VNV	 scenario	 –	A	 VNV	 flight	 plan	is	entered	 and	enabled,	 however	 Pitch	Hold,	 Vertical	
Speed, or Flight Level Change Mode can be used to descend to the VNV Target Altitude prior to reaching the 
planned	TOD.		Flight	Level	Change	Mode	is	used	in	the	example.
Flight Level Change descent:
1) Select Flight Level Change Mode:
a) Using the ALT SEL Knob, set the Selected Altitude to 10,000 feet.
b) Press the FLC Key to activate Flight Level Change Mode.  The annunciation ‘FLC’ appears next to the 
Airspeed Reference, which defaults to the current aircraft airspeed.  Selected Altitude Capture Mode is armed 
automatically.
c) If desired, press the SPD Key to display the Airspeed Reference in Mach.
2) Use the NOSE UP/DN Wheel or push the CWS Button while hand-flying the aircraft to adjust the commanded 
airspeed while maintaining the same power, or reduce power to allow descent in Flight Level Change Mode 
while the autopilot maintains the current airspeed.
3) As the aircraft nears the Selected Altitude, the flight director transitions to Selected Altitude Capture Mode, 
indicated by the green ‘ALTS’ annunciation flashing for up to 10 seconds.
 The green ‘ALT’ annunciation flashes for up to 10 seconds upon reaching 50 feet \
from the Selected Altitude; the 
autopilot transitions to Altitude Hold Mode and levels the aircraft.

AUTOMATIC FLIGHT CONTROL SYSTEM
Vertical  Path Tracking  descent  to VNV Target Altitude:
1) Select VNV flight control:
a) Press the VNV Key to arm Vertical Path Tracking Mode.  The white annunciation ‘VPTH’ appears.
b) Using the ALT SEL Knob, set the Selected Altitude 75 feet below the flight plan’s VNV Target Altitude of 10,000 
feet.
 If the Selected Altitude is not at least 75 feet below the VNV Target Altitude, the flight director will capture the 
Selected Altitude rather than the VNV Target Altitude once Vertical Path Tracking Mode becomes active (ALTS 
will be armed rather than ALTV).
c) If Vertical Path Tracking Mode is armed more than 5 minutes prior to descent path capture, acknowledgment is 
required for the flight director to transition from Altitude Hold to Vertical Path Tracking Mode.  To proceed with 
descent path capture if the white ‘VPTH’ annunciation begins flashing, do one of the following
 • Press the VNV Key
 • Turn the ALT SEL Knob to adjust the Selected Altitude
 If the descent is not confirmed by the time of interception, Vertical Path Tracking Mode remains armed and the 
descent is not captured.
2) When the top of descent (TOD) is reached, the flight director transitions to Vertical Path Tracking Mode and 
begins the descent to the VNV Target Altitude.  Intention to capture the VNV Target Altitude is indicated by the 
white ‘ALTV’ annunciation.
3) As the aircraft nears the VNV Target Altitude, the flight director transitions to VNV Target Altitude Capture Mode, 
indicated by the green ‘ALTV’ annunciation flashing for up to 10 seconds.
 The green ‘ALT’ annunciation flashes for up to 10 seconds upon reaching 50 feet \
from the VNV Target Altitude; 
the autopilot transitions to Altitude Hold Mode and levels the aircraft at the vertical waypoint.

Non-path descent using Flight Level Change Mode:
1) Command a non-path descent to an intermediate altitude above the next VNV flight plan altitude.  Use Flight 
Level Change Mode:
a) Using the ALT SEL Knob, set the Selected Altitude below the current aircraft altitude to an altitude (in this case, 
9,400 feet) at which to level off between VNV flight plan altitudes.
b) Press the FLC Key before the planned TOD during an altitude hold while VPTH is armed.  The Airspeed Reference 
defaults to the current aircraft airspeed.  Vertical Path Tracking and Selected Altitude Capture Mode are armed 
automatically.
2) Reduce power to allow descent in Flight Level Change Mode.  The autopilot maintains the Airspeed Reference.
3) As the aircraft nears the Selected Altitude, the flight director transitions to Selected Altitude Capture Mode, 
indicated by the green ‘ALTS’ annunciation flashing for up to 10 seconds.
 The green ‘ALT’ annunciation flashes for up to 10 seconds upon reaching 50 feet \
from the Selected Altitude; the 
autopilot transitions to Altitude Hold Mode and levels the aircraft.  After leveling off, reset the Selected Altitude 
at or below 9000 ft.
4) When the next TOD is reached, Vertical Path Tracking becomes active (may require acknowledgment to allow 
descent path capture).
5) As the aircraft nears the VNV Target Altitude, the flight director transitions to VNV Target Altitude Capture Mode, 
indicated by the green ‘ALTV’ annunciation flashing for up to 10 seconds.
 The green ‘ALT’ annunciation flashes for up to 10 seconds upon reaching 50 feet \
from the VNV Target Altitude; 
the autopilot transitions to Altitude Hold Mode and levels the aircraft at the vertical waypoint.

APPROACH
 NOTE: If an approach contains a DME arc, the arc must be flown in Navigation Mode with the GFC 700.  
When receiving vectors from ATC, Navigation Mode must be selected prior to intercepting the ARC.
Flying an ILS approach:
1) Transition from GPS Navigation Mode to Heading Select Mode.
a) Select the Runway 35L ILS approach for KCOS and select ‘VECTORS’ for the transition.  Load and activate the 
approach into the flight plan.
b) Use the HDG Knob to set the Selected Heading after getting vectors from ATC.
c) Press the HDG Key.  The autopilot turns the aircraft to the desired heading.
d) Use Heading Select Mode to comply with ATC vectors as requested.
2) Arm LOC Approach and Glideslope modes.
a) Ensure the appropriate localizer frequency is tuned.
b) Press the APR Key when cleared for approach to arm Approach and Glideslope modes.  ‘LOC’ and ‘GS’ appear 
in white as armed mode annunciations.
c)  The navigation source automatically switches to LOC.  After this switch occurs, the localizer signal can be captured 
and the autopilot and flight director determine when to begin the turn\
 to intercept the final approach course.  The 
flight director now provides guidance to the missed approach point.
3) There are two options available at this point, as the autopilot flies the ILS approach:
 • Push the AP DISC Switch at the decision height and land the aircraft
 • Use the GA Switch to execute a missed approach.

GO AROUND/MISSED APPROACH
 NOTE: As a result of calculations performed by the system while flying the h\
olding pattern, the display may 
re-size automatically and the aircraft may not precisely track the holdi\
ng pattern as depicted on the PFD and 
MFD.
Flying a missed approach:
1) Push the GA Switch at the Decision height and apply go around power to execute a missed approach.  The 
flight director Command Bars establish a nose-up climb to follow.  If flying an ILS or LOC approach the CDI also 
switches to GPS as the navigation source.
 Note that when the GA Switch is pushed, the missed approach is activated and the autopilot disconnects, 
indicated by the ‘AP’ annunciation flashing yellow for 5 seconds and the autopilot di\
sconnect aural alert.
