LPV, LNAV+V, and L/VNAV approaches will downgrade to
LNAV if GPS integrity cannot be met. There is no need to
switch to guidance by other navigation equipment unless
GPS LNAV is insufficient or integrity degrades further.
• Within 31 nautical miles of the destination airport, CDI
scaling will transition from 2.0 NM (en route mode, or
"ENR") to 1.0 nautical mile (terminal mode, or "TERM").
Conversely, when leaving the departure airport, CDI scal-
ing will transition from 1.0 NM to 2.0 NM when 30 miles
out. GPS-based approaches will see a second transition
when within 2.0 NM of the final approach fix, scaling from
1.0 NM to angular full-scale deflection (approach mode, or
"LNAV, L/VNAV, LNAV+V, or LPV").
• A "Left to xxx° in x sec" or "Right to xxx° in x sec" prompt
will appear in the lower right corner of the display to
remind you to initiate a procedure turn (if you haven't
already begun the procedure turn). The procedure turn is
displayed on the Default NAV and Map pages, but guid-
ance through the turn itself is not provided except via roll
steering-equipped autopilots.
• Alerts for proper holding pattern entry (e.g., "Hold
direct") are displayed in the lower right corner of the
display. Waypoint sequencing is automatically suspended
(indicated by "SUSP" directly above the OBS key) at the
holding waypoint. Press the OBS key again to return to
automatic waypoint sequencing. For course reversals,
waypoint sequencing is suspended for one trip around the
holding pattern only (after which it will return to auto-
matic waypoint sequencing).
• The CDI will guide you through a DME arc. Just keep the
needle centered as you fly along the arc.
• As you cross the missed approach point (MAP), "SUSP"
will appear above the OBS key, indicating that automatic
sequencing of waypoint is suspended at the missed
approach point, and a FROM indication will appear on the
CDI (or HSI).
APPROACHES

Flying the Missed Approach

1.
After crossing the missed approach point, press the
OBS key.The next waypoint in the approach is auto-
matically offered as the destination waypoint.
2.
Follow the missed approach procedures, as pub-
lished on your approach plate, for proper climb and
heading instructions.
3.
An alert message in the lower right hand corner of
the screen will recommend entry procedures for a
holding pattern (i.e.,"Hold direct","Hold parallel",
or "Hold teardrop").As you fly the holding pattern,
a timer appears on the Default NAV Page.The timer
automatically resets on the outbound side of the
hold when you are abeam the hold waypoint. The
timer again resets as you turn inbound (within
approximately 30° of the inbound course). This
allows you to use standard timing (typically one
minute) to fly the inbound and outbound legs of
the hold.
