Approach Procedures
4-7
ILS APPROACH INCLUDING GLIDE SLOPE INTERCEPT
When flying a Vectors-To-Final approach, use 1 of 2 techniques:
1. Use the Vectors-To-Final selection in the FMS900w drop
down windows to select that type of transition to the
localizer final and the “HDG” button on the autopilot
control panel and control the aircraft vector via the
Heading knob on the keyboard. (

);
2. Use the Heading knob on the keyboard and the “HDG”
button on the autopilot control panel when ATC is issuing
vectors.
NAV APPR can be armed prior to capturing the localizer beam
but it is highly recommended to wait until ATC clears you for the
approach before arming NAV and APPR. To arm NAV APPR
while still in Heading/Vectors mode, press the “NAV” (or “APPR”)
button. Once armed, the system will automatically capture the
localizer signal and transition out of Heading mode on its own.
□
Ensure the Primary Nav LSK is set to a VHF source
(NAV1 or NAV2) and tuned to a properly identified ILS
and the ILS is loaded in the FMS900w
□
Press “NAV” or “APPR” on the autopilot control panel
(Approach mode will automatically arm if tuned to an ILS
frequency)
□
The autopilot will enter NAV and Approach lateral modes
or arms them if off course
□
The autopilot will automatically arm the GS vertical mode,
retaining the existing vertical mode until capture
□
At this point, “NAV” and “APPR” buttons along with the
previous vertical buttons will be lit green on the autopilot
control panel and the “GS” button will be lit in cyan
□
PFD mode annunciator will display
NAV
and
APPR
along
with the previous vertical mode in green and
GS
in cyan
□
When the autopilot captures glideslope, the vertical mode
button on the autopilot control panel and mode
annunciator on the PFD will transition to a flashing green
