Autothrottle Operation
To activate or reactivate an autothrottle mode: AUTOTHROTTLE ARM switch ....................................................ARM If pitch mode TO/GA:
TO/GA switch .............................................................................Push Verify THR REF displays on flight mode annunciation. If pitch mode ALT, V/S, G/S, or no pitch mode: SPEED switch .............................................................................Push Verify SPD displays on flight mode annunciation. To set desired airspeed: IAS/MACH selector ............................................................ Rotate Set desired speed in IAS/MACH window. If FLCH desired: FLCH switch ..........................................................................Push Pitch mode changes unless G/S and LOC captured. Verify THR, IDLE, or HOLD displays on flight mode annunciation. If VNAV desired: VNAV switch ........................................................................Push Pitch mode changes when in V/S or ALT. Verify THR REF, THR, SPD, IDLE, or HOLD displays on flight mode annunciation. If TO/GA is desired: TO/GA switch ........................................................................Push Pitch and roll modes change to TO/GA. Verify THR or THR REF displays on flight mode annunciation. If pitch mode is VNAV PTH, VNAV ALT, VNAV SPD, or FLCH SPD: AUTOTHROTTLE ARM switch ..............................OFF, then ARM Verify THR REF, THR, SPD, IDLE, or HOLD displays on flight mode annunciation.

Localizer Approach
Pitch mode may be VNAV or V/S . If using VNAV, verify proper approach and altitudes have been entered in the CDU and use speed intervention for airspeed control.
LOCALIZER switch ........................................................................ Push When on an intercept heading to the localizer course with PFD localizer pointer displayed, push LOC switch. Verify the armed roll flight mode annunciation is LOC. Verify the engaged roll flight mode annunciation is LOC upon localizer capture. Prior to descent to minimum descent altitude(MDA): ALTITUDE window – Set
Set intermediate altitude constraint or MDA if no intermediate altitude
constraint exists.
In descent, set each intermediate altitude constraint and MDA.
If constraints or MDA do not end in 00 (for example, 1820), set ALT
window to closest 100 foot increment below.
If using VNAV:
Prior to minimum descent altitude:
Missed approach altitude – Set
Set in ALT window.
At minimum descent altitude and landing:
Autopilot disengage switch – Push
Disengage autopilot before descending below MDA.
Autothrottle disconnect switch -Push
Disconnect autothrottle before descending below MDA.
At minimum descent altitude and circling to land:
ALTITUDE HOLD switch – Push
If landing:
Autopilot disengage switch -Push Disengage autopilot before descending below MDA.

SP.4.4 D6-30151-425 December 01, 1999
Supplementary Procedures -Automatic Flight
Autothrottle disconnect switch -Push Disconnect autothrottle before descending below MDA. If using V/S: At descent point: VERTICAL SPEED switch – Push Verify V/S displays in flight mode annunciation. Desired vertical speed – Set Set desired vertical speed to descend to MDA. At minimum descent altitude, straight-in or circle-to-land: ALTITUDE HOLD switch -Push Missed approach altitude – Set Set in ALT window. If landing: Autopilot disengage switch – Push Disengage autopilot before descending below MDA. Autothrottle disconnect switch -Push Disconnect autothrottle before descending below MDA.

Localizer Back Course Approach
Pitch mode may be VNAV or V/S. When using VNAV, verify proper approach and altitudes have been entered in the CDU and use speed intervention for airspeed control.
Roll mode may be LNAV or HDG SEL. If LNAV does not track correct course, use HDG SEL.
Observe PFD localizer pointer.
