DA(H).
When reaching the DA(H) or MDA(H), be prepared to disengage the autopilot and
land or execute an immediate go-around.
Note: If using an MDA(H), initiating a missed approach approximately 50 feet
above MDA(H) may be necessary to avoid descending below the MDA(H)
during the missed approach, if required for the procedure or by the
regulatory authority.

The pilot monitoring should expand the instrument scan to include outside visual
cues when approaching DA(H) or MDA(H). Do not continue the approach below
DA(H) or MDA(H) unless the airplane is in a position from which a normal
approach to the runway of intended landing can be made and suitable visual
reference can be maintained. Upon arrival at DA(H) or MDA(H) or any time
thereafter, if any of the above requirements are not met, immediately execute the
missed approach procedure.
When suitable visual reference is established, maintain the descent path to the
flare. Do not descend below the visual glide path. While VNAV PTH guidance
may still be used as a reference once the airplane is below DA(H) or MDA(H), the
primary means of approach guidance is visual.
Note: VNAV path guidance transitions to level flight once the missed approach
fix is passed.
Simulated Instrument Approach Using VNAV
To maintain proficiency, crews may practice instrument approach using VNAV
procedures while flying ILS approaches as follows:
• ensure the ILS is tuned and identified and the ILS raw data is monitored
throughout the approach
• track the localizer using LOC or LNAV as the roll mode
• use VNAV as the pitch mode to track the GP angle. The charted GP angle
normally coincides with the ILS glide slope angle
• disengage the autopilot by the minimum altitude specified in the
Limitations chapter of the FCOM.
Note: Limit the use of the above technique to VMC weather conditions.
In ambient temperature conditions warmer than ISA standard, the airplane may
remain slightly high relative to the ILS glide slope, and in temperatures colder
than ISA standard, the airplane may remain slightly lower than the ILS glide
slope. Discontinue use of this technique and manually track the localizer and glide
slope if localizer or glide slope deviations become unacceptable.

Use of IAN - General
The approach profile illustrated depicts crew actions used during an approach
using Integrated Approach Navigation (IAN). Since IAN approach techniques are
similar to ILS approach techniques, only items considered unique to IAN are
discussed in the remainder of this section. The approach profile illustrated
assumes all preparations for the approach such as review of the approach
procedure and setting of minima and radios, as required, are complete.
