APPROACH
XFEED.......................................................................... OFF
PASS SIGNS Panel...................................................... SET
AIR COND/PNEUMATIC Panel.................................... SET
Altimeters...................................................................... SET &
XCHECKED
When the altimeters are set to QNH (passing the Transition Level)
the Approach Checklist should be called for, if it is a flight in ICAO
airspace. If the flight is in other than ICAO airspace, checklist must
be called for at an altitude established as operational standard.
Verify that both altimeters and the standby altimeter are set to
QNH.
Approach Aids .............................................................. SET &
XCHECKED
NOTE: The VAPP mode should be selected only on final approach
segment, below 2500 ft AGL. Therefore, the outbound
segment should be flown using any other mode.
Both pilots must verify that the frequencies and courses that were
selected are correct for the intended approach. Ensure that both
PFD’s are displaying appropriate information.
They must also verify that the radio altimeter alert (DH) and the
FMS are properly selected for the type of approach in mind.
CAUTION:
RADIO ALTIMETER-BASED DECISION HEIGHTS ARE
NOT RECOMMENDED ON CAT I APPROACHES. THE
DECISION ON A CAT I APPROACH HAS TO BE BASED
ON THE ALTIMETER RATHER THAN ON THE RADIO
ALTIMETER. THE DH ALERT IN THESE CASES IS A
REFERENCE ONLY THAT MUST BE USED WITH CARE
AND ITS VALIDITY DEPENDS ON THE PILOTS'
KNOWLEDGE OF THE TERRAIN BEFORE THE
RUNWAY. ALTIMETER-BASED DECISIONS ARE NOT
ALLOWED ON CAT II APPROACHES. THE DECISION
ON THESE APPROACHES HAS TO BE BASED ON THE
RADIO ALTIMETER.
