EHSI Displays
4.1.11 Issued 4/95 SW 06/07/08/11
provided by an LNAV in the
approach mode, however after
08 SW, this scaling can be con-
figured to be ±1000, ±500, ±250,
or ±200 feet.
If the selected sensor is ILS, a
“GS” will be displayed in the verti-
cal pointer. When MLS is the
selected sensor, this annuncia-
tion will be “GS” for SW 06 and
07, but beginning with SW 08,
either “GS” or “GP” (for Glide
Path) may be annunciated. “VN”
will be annunciated if the select-
ed sensor is an LNAV with VNAV
selected. When MLS is the
selected sensor, the selected
glide path angle is displayed
above the glideslope deviation
scale. If VNAV is displayed “FT”
(feet) or “AN” (angle) will be
annunciated above the vertical
deviation scale.
If the vertical deviation data
becomes invalid, the course devi-
ation bar and scale are removed
and replaced with a RED X
annunciation.
Additional configuration options
selectable at the time of installa-
tion and certification:
❏ Declutter GS on Back
Course, allows the vertical
deviation scale to be in view
at all times or only when the
selected course is within
105 degrees of the aircraft
heading.
Vertical Scale Side, allows the
vertical deviation scale to be
displayed on either the:
❏ Right or
❏ Left side of the EADI and
EHSI display.
VNAV Approach Mode Scaling,
a configuration option added
by software 08, allows the fol-
lowing values for a full scale
VNAV approach deviation.
❏ 1000 feet
❏ 500 feet
❏ 250 feet
❏ 200 feet
Vertical Pointer Type, selected
at the time of certification.
Vertical Pointer Annunciation
for MLS A configuration option
added by software 08, allows the
choice of two pointer annuncia-
tions when an MLS is the select-
ed primary NAV sensor.
❏ GS
❏ GP
If invalid or failed glide slope or
VNAV data is received, the verti-
cal deviation bar and scale are
removed and replaced with a
RED X annunciation.
Beginning with software 11, the
vertical deviation bar and scale
are decluttered without displaying
a RED X when the deviation
information is provided in ARINC
429 format with a status of NO
COMPUTED DATA (NCD). The
RED X is still displayed for invalid
or missing data.
