PITCH HOLD MODE (PIT)
When	the	flight	 director	 is	activated	 (the	FD Key is pressed) or switched (the XFR	Key	 is	pressed),	 Pitch	Hold	
Mode	 is	selected	 by	default.		 Pitch	Hold	Mode	 is	indicated	 as	the	 active	 vertical	 mode	by	the	 ‘PIT’	 annunciation.		
This mode may be used for climb or descent to the Selected Altitude (shown above the Altimeter), since 
Selected Altitude	Capture	Mode	is...

SELECTED ALTITUDE CAPTURE MODE (ALTS)
Selected Altitude Capture Mode is automatically armed with activation of the following modes:
•	 Pitch
The	white	 ‘ALTS’	 annunciation	 indicates	Selected	Altitude	Capture	Mode	is	armed	 (see	Figure	 7-6	for	example).		
The ALT SEL Knob is used to set the Selected Altitude (shown above the Altimeter)\

ALTITUDE HOLD MODE (ALT)
Altitude Hold Mode can be activated by pressing the A LT Key; the flight director maintains the current aircraft 
altitude (to the nearest 10 feet) as the Altitude Reference.  The flight director’s Altitude Reference, shown in the 
AFCS	Status	 Box,	is	independent	 of	the	 Selected	 Altitude,	 displayed	 above	the	Altimeter.		 Altitude	Hold	Mode	
active	is	indicated	by	a	green...

VERTICAL SPEED MODE (VS)
In	Vertical	 Speed	Mode,	 the	flight	 director	 acquires	 and	maintains	 a	Vertical	 Speed	Reference.		 Current	aircraft	
vertical speed (to the nearest 100 fpm) becomes the Vertical Speed Reference at the moment of Vertical Speed 
Mode activation.  This mode may be used for climb or descent to the Selected Altitude (shown above the 
Altimeter) since Selected Altitude Capture...

FLIGHT LEVEL CHANGE MODE (FLC)
 NOTE: The Selected Altitude should be set before selecting Flight Level Change Mode.
Flight Level Change Mode is selected by pressing the FLC Key.  This mode acquires and maintains the 
Airspeed	Reference	 (in	IAS	 or	Mach)	 while	climbing	 or	descending	 to	the	Selected Altitude (shown above 
the	 Altimeter).		 When	Flight	Level	Change	 Mode	is	active,	 the	flight...

CHANGING THE AIRSPEED  REFERENCE
The	Airspeed	 Reference	 (shown	in	both	 the	AFCS	 Status	 Box	and	above	 the	Airspeed	 Indicator)	 may	be	
adjusted by:
•	 Using	the	NOSE UP/DN	Wheel
•	 Pressing	 the	CWS Button, hand-flying the aircraft to attain a new Airspeed Reference, then releasing the 
CWS Button
 NOTE: If the Selected Altitude is reached during CWS maneuvering, the Altitude Reference is not...

Prior	to	descent	 path	interception,	 the	Selected	 Altitude	must	be	set	 below	 the	current	 aircraft	altitude	
by	at	least	 75	feet.	 	 For	the	flight	 director	 to	transition	 from	Altitude	 Hold	to	Vertical	 Path	Tracking	 Mode,	
acknowledgment is required within five minutes of descent path interception by:
•	 Pressing	the	VNV Key
•	 Adjusting	the	Selected	Altitude

When	a	descent	 leg	is	captured	 (i.e.,	vertical	 deviation	 becomes	valid),	Vertical	 Path	Tracking	 becomes	
active	and	tracks	 the	descent	 profile	(Figure	 7-14).		An	altitude	 capture	mode	(‘ALTS’	 or	‘ALTV’)	 is	armed	 as	
appropriate.
