Activating an Approach

With an approach loaded

in the active flight plan,

press the PROC key to

display the procedures

page.

Turn the large right

knob to highlight "Activate Approach?".

Press the ENT key.

Activating an Approach with Vectors-To-Final

The "Activate Vector-To-Final?" option allows you

to activate the final course segment of the approach.

This option assumes you will receive vectors to the final

approach course and guides you to intercept the final

course, before reaching the FAF.

With an approach loaded

in the active flight plan,

press the PROC key to

display the procedures

page.

Turn the large right

knob to highlight "Activate Vector-To-Final?".

Press the ENT key.

Flying an Approach

Due to the variety of available approach procedures, the

specific steps required will vary according to the approach

selected. Keep the following general guidelines in mind

while flying the approach:

• The 400W series is designed to complement your

printed approach plates and improve situational

awareness throughout the approach. However, you

must always fly an approach as it appears on the

approach plate.

APPROACHES

• You will typically select the destination airport as the

last waypoint in the active flight plan or by using the

direct-to key. Doing so ensures that the desired waypoint

will automatically appear when choosing the "Select

Approach?" option from the procedures page. Otherwise,

you must first choose the airport, then the approach

procedure.

• When a localizer-based approach (such as an ILS) is

loaded, the desired frequency is automatically placed in

standby on the VLOC window. To activate the frequency,

press the VLOC flip/flop key.

• If the VLOC receiver will be used for the approach, be

sure to switch the external CDI (or HSI) to "VLOC" by

pressing the CDI key. "VLOC" will appear directly above

the CDI key.

• An "Auto ILS CDI" setting provides automatic switching

to "VLOC" as you intercept the final approach course.

When the ILS approach is activated (and the correct

frequency is active in the VLOC window), the unit will

automatically switch within 1.2 nautical miles left or right

of the approach course. This switch can take place any-

where from 2.0 to 15.0 nautical miles from the FAF. The

switch occurs gradually to prevent abrupt CDI changes.

This does not occur automatically when configured for the

King KAP140/KFC225 autopilots as Auto ILS CDI Selection

is not allowed.

• As you progress to each approach waypoint, a waypoint

alert message ("NEXT DTK ###°") will appear in the

lower right corner of the display.

• When you should begin a course change (via a standard

rate turn), turn advisories ("TURN TO ###°") will appear

in the lower right corner of the display.

• For GPS-based approaches, receiver autonomous integ-

rity monitoring (RAIM) will monitor satellite conditions

and alert you—using an "INTEG" at the bottom left

corner of the display — if protection limits cannot be
