H. Display after pressing CANCEL UPDATE LSK:
MOD/" " (title):
MOD indicates an active flight plan modification has not been EXECuted yet; otherwise, the
field is blank.
REF [1L]:
This field displays the reference position. Successively pressing this LSK with an empty scratchpad,
the REF changes between the system position (FMS), and a waypoint ID entry prompt (----).
When the waypoint ID entry prompt (----) is displayed the user can specify a waypoint ID via the scratchpad.
When this page is accessed via the MARK key on the CARP PROGRESS page this field will contain the IP
identifier by default. When FMS is displayed the FMS computed position is used as reference. This is the default
state when accessed via the UPDATE POS 1/2 page.
BRG/DIST/XTK OFFSET [1R]:
This field displays the vector that is added to the REF ID position to generate
the UPDT POS position. Two formats are supported. Except when the reference is FMS, pressing the LSK with
an empty scratchpad causes the display to toggle between the two formats.
The default format is BRG/DIST: bearing (in degrees clockwise from North - either True or Magnetic depending
on setup page) and distance (in nautical miles). The default values for the BRG/DIST format are 0 with valid
range of 0 to 360 degrees and 0.00 to 99.9 nautical miles.
The second format is XTK OFFSET and is not available when REF is FMS: cross-track distance from the REF
position to the closest point along the path passing through the aircraft position and in the direction of the
heading. L indicates the aircraft is to the left of the ID point, R is to the right. The default value is R0 with valid
range from 000 to 999 feet.
UPDATE POSITION [2L]:
This field displays the position from which the marked FMS position is to be
subtracted to compute a position correction vector. Once the position update is completed and executed, this
position correction vector is subtracted from the CARP procedure waypoint positions. UPDATE POSITION may
be entered manually via the scratchpad; otherwise it is computed as the sum of the REF position and the
BRG/DIST or XTK OFFSET vector.
When entered manually, the REF and BRG/DIST fields are set to ----; otherwise
When the REF is FMS, this field changes value as the FMS position changes until the MARK LSK is pressed, at
which time it is frozen.
When the REF is a waypoint ID, this field is static.
MODE (4L):
This field displays the marked FMS navigation mode.
ACCUR (4L):
This field displays the horizontal position accuracy of the marked FMS position (in nautical miles).
