ALT INTV switch.............................................................................Push If a higher altitude is selected, a CRZ climb will be initiated. If a lower altitude is selected, an early descent will be initiated.
Intervention of FMC Altitude Constraints during VNAV Descent YD651 - YD655
MCP altitude selector .....................................................Set new altitude New altitude must be lower than the FMC altitude constraint (s) to be deleted.
ALT INTV switch.............................................................................Push
Each push of the ALT INTV switch will delete an FMC altitude constraint. If all FMC altitude constraints are deleted, the descent mode will
revert to a VNAV speed descent.
Intervention of FMC Airspeed Constraints during VNAV YD651 - YD655
SPD INTV switch.............................................................................Push MCP IAS/MACH display shows current FMC target speed. IAS/MACH Selector ....................................................Set desired speed VNAV remains engaged. To resume former FMC speed: SPD INTV switch........................................................................Push MCP IAS/MACH display blanks and FMC commanded VNAV speed is active.
Altitude Hold
Altitude HOLD switch .....................................................................Push Verify FMA display: Pitch mode – ALT HOLD

Heading Select
Heading selector........................................................Set desired heading Heading select switch....................................................................... Push Verify FMA display: Roll mode – HDG SEL
VOR Navigation
VHF NAV radio(s) .......................................................Tune and Identify
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.
Instrument Approach using VNAV
Note: This procedure is not authorized using QFE.
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, a 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.

737 Flight Crew Operations Manual
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 prior to the FAF and after ALT HLD or VNAV PTH 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.]
