· These approaches are restricted to BCD with GPS updating.
· The approach must be selected from the NAV database.
· The approach requires a manual RNP entry of .3nm.
· Utilize LNAV for course tracking and VNAV for tracking the gradient
path.
· A Decision Altitude (DA) or Derived Decision Altitude (DDA), whichever
is appropriate, is set for minimums on the barometric altimeter.
ASR
Surveillance Approach Radar (ASR) provides the controller with azimuth and
range information to a specific runway or series of runways. An approved
approach lighting system enhances the approach and allows lower landing
minimums. ASR procedures must include controller instructions regarding lost
communications procedures. The final approach segment begins at the final
approach fix and ends at the missed approach point. The pilot will be notified
when approaching the FAF, when to begin descent to the MDA, and where
instructions to take over visually and land or miss the approach are to be
received.
MDA’s are published on the applicable Jeppesen Approach Chart and the
controller is required to issue the MDA when the descent notification is issued.
Recommended altitudes on final will not be issued by the controller unless the
pilot requests them. If the aircraft deviates to the left or right of centerline, the
controller will make notification using the phraseology “slightly” or “well” to
the left or right of desired track. In addition, the controller may use the
phraseology “rapidly” or “slowly” when referencing the closure rate or
deviation from the desired track. A pilot may expect to be issued a go-around
(missed approach) if the aircraft proceeds outside the specified safety zone
limits unless the runway environment is in sight. The ASR approach terminates
when the pilot reports the runway in sight or the aircraft is over the missed
approach point.
ASR approaches will be briefed and flown in accordance with the published
ASR approach procedure. In general, the approach will be flown using the
MCP in HDG SEL for roll control and vertical speed for pitch control. The
pilot will not engage LNAV or VNAV while conducting the ASR approach.
ATC provides azimuth and range information, therefore, both pilots may be in
the MAP mode. The approach may be constructed in the CDU, but displayed
LNAV and VNAV data is to be used for reference only and it is mandatory to
comply with all controller instructions during the approach.

HDG SEL should be used for tracking. ATC provides all azimuth directions (and
recommended altitudes on final, if requested). Use V/S for the descent.
Consider selecting the appropriate RWY selection from DEP/ARR and using
the runway extension (RWY EXT) function. RWY EXT appears after RWY
selection and before pressing EXECute. It allows entry of a desired mileage.
Using 6 miles will generate a RXxx waypoint 6 miles from the end of the
runway and approximate a descent point from 2000 ft above TDZE. Select a
mileage appropriate for the expected altitude loss.

NON-PRECISION SETUP REFERENCE
Approach Preparation
DEP/ARR Key Select Approach from database and verify accuracy
(including Missed Approach).
LEGS Page Verify (GPx.xx) is available. (Approaches without a
Gradient Path require use of VERT SPD.)
At-or-Above Altitudes (approach portion only) – make them
“Hard” altitudes.
6L: Manual entry of RNP (if raw data is not controlling).
Approach plate or QRH for RNP value.
APPROACH
REF Page
VREF select.
WIND CORR select (if other than +5kts).
CRZ Page Verify CRZ ALT was achieved. If not, this will inhibit VNAV
engagement.
ALTIMETER
Setup
Barometric DA / DDA set. DDA computation is (MDA + 50
feet). (ballflag note, if appropriate)
Radio Altimeter set 250 feet.
Vertical Speed
Contingency
Brief the VERT SPD contingency in the event VNAV will
not engage. Brief reference to the PDI.
This can be accomplished from the Approach Plate or the
QRH.
