IAS/MACH Selector.....................................................Set desired speed
Vertical Speed (V/S) Climb/Descent
ALTITUDE selector ..................................................Set desired altitude Note: If a new MCP altitude is selected while in ALT ACQ, the AFDS engages in V/S and the existing vertical speed is maintained. V/S thumbwheel ..............................................Set desired vertical speed
Verify FMA display:
Thrust mode (climb or descent) – MCP SPD
Pitch mode – V/S
Speed selector ...............................................................Set desired speed To transition to the vertical speed mode from another engaged climb or descent mode: V/S mode switch .........................................................................Push V/S climb mode engages at existing V/S.
V/S thumbwheel .........................................Set desired vertical speed
Supplementary Procedures -Automatic Flight 737 Operations Manual
Verify FMA display:
Thrust mode (climb or descent) – MCP SPD
Pitch mode – V/S
Speed selector ......................................................... Set desired speed Note: (As installed.) During V/S mode operation, if airspeed becomes more than 5 knots below the MCP selected airspeed and is not increasing, the AFS automatically engages the LVL CHG mode.
Intermediate Level Off (VNAV)
ALTITUDE selector ...................................................Set desired altitude
At MCP altitude:
Verify pitch mode displays ALT HOLD
To continue climb/descent:
ALTITUDE selector..............................................Set desired altitude
VNAV switch .............................................................................. Push
Verify FMA display:
Thrust mode (climb) – N1
Thrust mode (descent) – RETARD then ARM
Pitch mode – VNAV SPD or VNAV PTH as appropriate
Altitude Hold
Altitude HOLD switch ..................................................................... Push Verify FMA display: Pitch mode – ALT HOLD
Heading Select
Heading selector........................................................Set desired heading
Heading select switch....................................................................... Push

Supplementary Procedures -Automatic Flight 737 Operations Manual
Verify FMA display:
Roll mode – HDG SEL
VOR Navigation
VHF NAV radio(s)............................................................................Tune
COURSE selector ........................................................Set desired course
When on an intercept heading to the VOR course:
VOR LOC mode switch ..............................................................Push Verify VOR LOC armed mode annunciates. A/P automatically captures the VOR course. Verify VOR LOC engaged mode annunciates upon course capture.
Note: If change to a localizer frequency is desired when captured in the VOR mode, disengage VOR LOC mode prior to selection of the localizer. VOR LOC mode can then be reengaged.
Supplementary Procedures -Automatic Flight 737 Operations Manual
Instrument Approach using VNAV
Note: This procedure is not authorized using QFE.
Note: This procedure requires FMC U7.1 or later.
Note: Operational approval required for the use of an MDA(H) as a DA(H). If required to remain at or above MDA(H) during the missed approach, missed approach must be initiated at least 50 feet above MDA(H).
Recommended roll modes for final approach:
.
RNAV, GPS or TACAN approach: LNAV
.
LOC-BC, VOR or NDB approach: LNAV or HDG SEL
.
LOC, SDF or LDA approach: VOR/LOC or LNAV. For LOC, LOC-BC, SDF or LDA approaches, ensure appropriate navaids are tuned and identified prior to commencing the approach and monitor raw data
throughout the approach. For VOR and NDB approaches, raw data should be monitored, if available.
FMC approach procedure............................................................... Select
Select the approach procedure on the ARRIVALS page. Do not manually build the approach or add waypoints to the selected FMC procedure. Add cold temperature corrections to waypoint altitude constraints as appropriate.
Verify VNAV glide path angle is displayed on the final approach
segment of the LEGS page.
RNP appropriate for approach (if required) ......................... Verify/Enter [Allows appropriate alerting to occur if ANP exceeds RNP.]
Approximately 2 NM miles prior to the FAF and after ALT HLD or
VNAV PTH/VNAV ALT is engaged:
MCP altitude ......................................................Set MDA(H)/DA(H) [Allows VNAV to command descent in VNAV PTH. If the MDA(H)/DA(H) does not end in zero zero, for example, 1820, set MCP ALTITUDE window to the closest 100 foot increment above the constraint.] 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：737-300机组操作手册Flight Crew Operations Manual FCOM 1(55)
