737 Flight Crew Operations Manual
Prior to reaching MDA(H)/DA(H) and when the airplane is at least 300 feet below the missed approach altitude: MCP altitude ......................................... Set missed approach altitude
At MDA(H)/DA(H)/Missed approach point: If suitable visual reference is not established, execute a missed approach.
After suitable visual reference is established: A/P disengage switch............................................................. Push Disengage the autopilot before descending below MDA(H)/DA(H). A/T disengage switch ............................................................ Push Disengage the autothrottle before descending below MDA(H)/DA(H).
Instrument Approach using Vertical Speed (V/S)
Note: Autopilot use is recommended until suitable visual reference is established.
Note: If required to remain at or above the MDA during the missed approach, the missed approach must be initiated at least 50 feet above MDA.
Recommended roll modes:
.
RNAV, GPS, TACAN, LOC-BC, VOR or NDB approach: LNAV
or HDG SEL.
.
LOC, SDF or LDA approach: LOC or LNAV. Ensure appropriate navaids (VOR, LOC or NDB) are tuned and identified prior to commencing approach. RNP appropriate for approach (if required) .................... Verify/Enter Allows appropriate alerting to occur if ANP exceeds RNP.
Before descent to MDA(H): MCP altitude ............................................................................. Set

Supplementary Procedures -Automatic Flight 737 Flight Crew Operations Manual
Set the first intermediate altitude constraint or the MDA(H). When the current constraint is assured, the next constraint may be set prior to ALT HOLD is engaged to achieve continuous descent path.
If constraints or MDA(H) do not end in zero zero, for example, 1820, set MCP ALTITUDE window to the closest 100 foot increment above the constraint.
At descent point: Desired V/S ...............................................................................Set Set desired V/S to descend to MDA(H). Use a V/S that results in no level flight segment at the MDA(H). Verify V/S mode annunciates.
Approaching MDA(H): MCP altitude ....................................Set missed approach altitude
At MDA(H)/missed approach point: If suitable visual reference is not established, execute a missed approach. After a suitable visual reference is established:
A/P disengage switch........................................................Push Disengage the autopilot before descending below MDA(H). A/T disengage switch........................................................Push Disengage the autothrottle before descending below MDA(H).
Circling Approach
Note: Autopilot use is recommended until intercepting the landing
profile.
MCP altitude selector ..........................................................................Set
If the MDA(H) does not end in zero zero, for example, 1820, set MCP ALTITUDE window to the closest 100 foot increment above the MDA(H).
