Points to Remember for ALL Approaches

• TheGNS500W-seriesunitisdesignedtocomple-

ment your printed approach plates and vastly

improve situational awareness throughout the

approach. However, you must always ﬂy an approach

as it appears on the approach plate.

• Theactiveleg (or the portion of the approach

currently in use) is depicted in magenta on the

Map Page. As you ﬂy the approach, the 500W-

series unit automatically sequences through each

leg of the approach unless “SUSP” appears above

the OBS key. “SUSP” indicates that automatic

sequencing of approach waypoints is suspended on

the current leg and normally appears at holding

patterns and upon crossing the missed approach

point (MAP).

“SUSP” indicates that automatic sequencing

of approach waypoints is suspended. In some

instances “SUSP” automatically cancels (hold-

ing pattern entry). In other cases, press OBS to

manually cancel.

• Forrollsteering autopilots: roll steering is ter-

minated when approach mode is selected on the

autopilot and is available once the missed approach

is initiated.

• IfVectors-to-Finalisactivatedwhileonthe“FROM”

side of the FAF, automatic waypoint sequencing is

suspended and the SUSP annunciation will appear.

Automatic waypoint sequencing will resume once

the aircraft is on the “TO” side of the FAF and within

full-scale deﬂection. This is a new feature with the

500W-series.
