Observe autothrottle system FMA’s display SPD.
SPD Readout ........................................................................................SET
Rotate SPD / MACH knob to set 250 knots in SPD Readout. Observe
throttles retard to idle.
Note: Setting 250 initially in the SPD / MACH Readout assures throttles remain in idle and maintains a safe airspeed in the event of level off requirements. Adjust pitch wheel to maintain
0.80 Mach until 320 knots is attained. Maintain 320 knots to 3000 feet above speed limiting altitude.
At 3000 feet above speed limiting altitude:
Pitch Profile Readout...........................................................................SET
Rotate pitch wheel toward:ANU to reduce rate of descent until V-1500 appears in Pitch Profile Readout. Observe airplane decelerate so as to pass speed limiting altitude indicating required airspeed. Adjust pitch wheel as required for remainder of descent.

As flap / slat configuration changes:
SPD Readout ........................................................................................SET
Rotate SPD / MACH knob to set desired airspeed in SPD Readout.
Nearing initial approach altitude (no closer than 50 feet from selected level-off altitude), observe stead amber altitude advisory light come on. Observe light goes out when within 250 feet of selected altitude.
Note: Deviation from selected altitude is indicated by a flashing altitude advisory light and a two-second tone.
Returning to within 250 feet of reference altitude or selecting new reference altitude will turn off flashing lights.
DESCENT INITIATION IAS / MACH MODE
With FD switches in ON, AP switch in ON, AUTO THROT switch on (UP), and in MACH SEL mode:
ALT Readout........................................................................................SET
Rotate ALT SET knob until level-off altitude is displayed in ALT Readout.
Altitude Preselect Mode.....................................................................ARM
Pull ALT SET knob to engage altitude preselect mode.
Pitch Profile Readout...........................................................................SET
Rotate pitch wheel toward AND to initiate descent until V-2500 appears in
Pitch Profile Readout. VERT SPD will be displayed in pitch FMA’s.
When desired Mach or IAS is attained:
IAS / MACH Button .........................................................................PUSH
Observe pitch FMA’s indicate Mach or IAS as appropriate and ATS FMA’s switch to CLMP and flash for 5 seconds. If Mach is selected, Pitch Profile Readout will display M followed by Mach number. If IAS is selected, readout will display S followed by the indicated airspeed selected.
SPD / MACH Knob................................................................ PUSH / SET
Push full in on the SPD / MACH knob and set the required airspeed to be
used later in the descent and approach.
Note: If SPD SEL or MACH SEL autothrottle modes are re-established, IAS or MACH mode will be overridden automatically and pitch FMA’s will switch to VERT SPD or ALT HDL as appropriate, and pitch displays will flash for 5 seconds.
If in MACH or IAS mode, rotating the pitch wheel will change MACH or IAS displayed in Pitch Profile Readout.
If in CLMP, selecting a pitch mode other than MACH or IAS will cause CLMP mode to disengage and prior primary autothrottle mode to be re-established. Autothrottle system FMA’s will flash for approximately 5 seconds to alert crew of change.

FLIGHT DIRECTOR / AUTOPILOT VOR MODE
VHF NAV Readouts.............................................................................SET
Set and identify desired VOR frequency.
CRS Readouts ......................................................................................SET
Set desired for VOR course.
HDG Readout.......................................................................................SET
Rotate HDG selector knob until desired intercept heading appears in HDG Readout.
Note: If not already in HDG SEL mode, pull HDG selector knob and observe roll FMA’s display HDG SEL.
VOR / LOC Button...........................................................................PUSH
Observe arm FMA’s display VOR.
Note: Roll control responds to the selected heading and with autopilot engaged, VOR radial will be captured automatically. On the HSI, at approximately 2 dots on the course deviation indictor (CDI), VOR capture mode will engage and VOR CAP will be displayed in roll FMA’s.
