Approach Procedures
4-7
ILS APPROACH INCLUDING GLIDE SLOPE INTERCEPT
When flying a Vectors-To-Final approach, use the Heading knob
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 “HDG” and “NAV”
(or “HDG” and “APPR”) buttons at the same time. Once armed,
the system will automatically capture the localizer signal and
transition out of Heading mode on its own. In summary:
□
Ensure the Primary Nav LSK is set to a VHF source and
tuned to a properly identified ILS
□
Press “NAV” or “APPR” on the autopilot control panel
(Approach mode will automatically arm if tuned to an ILS
frequency when NAV is pressed)
□
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 (see
paragraphs below)
□
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
“
GS
” which will flash for approximately 10 seconds before
going steady green
□
Execute a missed approach, if appropriate
