CAT2 Excessive Deviation Monitors – When
the ILS excessive deviation monitors are active. If glideslope
deviation exceeds Category II window requirements with radio
altitude less than 600 feet, the glideslope deviation scale changes
from green to flashing amber, and the glideslope pointer changes
to a steady amber. The display reverts to
brought back within limits. The localizer deviation scale and pointer
operate the same way. The PFD
CAT2 and flashes when the conditions stated above are lost.
The glideslope and localizer excessive deviation monitors are
independent. They conform to tolerances set by regulatory aviation
agencies for Category II ILS operations.
D
Outrigger Boxes – Aligned on each end the horizon line,
outrigger boxes emphasize position of the horizon.
D
Vertical Deviation Scale and Pointer – The vertical deviation
scale and pointer indicate LRN vertical deviation or glideslope
deviation.
When flying VNAV, the flight director computes the vertical path
based on either a short range navigation (SRN) or LRN waypoint.
The vertical deviation pointer represents the vertical displacement
from that path.
The white vertical deviation scale is displayed on the right side of the
attitude sphere. The source for this scale is either the ILS glideslope
or VNAV, and is selected using the display controller.
The pointer colors are as follows:
— Green for ILS
— Cyan when flying to VOR/DME or FMS waypoints
— Yellow when both pilots select the same navigation source.
When invalid information is displayed from the ILS or MLS receiver,
the pointer is removed and an
scale is removed for invalid FMS data.
NOTE: When a back course is armed or captured by the flight
director, the vertical deviation scale is removed.
D
Marker Beacons – The outer (O), middle (M) and inner (I) marker
beacon annunciators are displayed in a white box under the vertical
deviation scale. When the aircraft passes over each marker beacon,
the annunciator flashes continuously. Normally, only one annunciator
is displayed at a given time. When the display controller TEST button
is pushed, all three annunciators are displayed simultaneously .
