The Initial Point (IP) page provides edit access to the offset steering function
available for use to take an indirect approach to a waypoint or target. The IP page
permits the pilot to assign an offset to a designated waypoint in delta X and delta Y
Cartesian coordinates (X/Y IP) or polar (Bearing/Range) coordinates (B/R IP).
Selecting the IP page displays the windows associated with the initial point function
on the UFCP.

W1 - Displays the offset mode, either B/R or X/Y,
right-justified.
Upon selection of the OFS page, W1 displays the

pressing W1 toggles between offset modes B/R
and X/Y and displays on both crew stations.

W2 - Allows the pilot to enter either the across
track distance (for an X offset) or the offset
bearing (for an R offset).
For an across track distance, the label is displayed
as X and the data is a number with up to four digits
indicating the across track distance, which has an
allowable range of 0 to 999.9 nm.
When the across track distance is entered using
the alphanumeric keyboard, the decimal point is
automatically displayed in the second character
position from the right.
The across track distance also has a selection of L
or R for offset distances to the left or right
of the track; this selection is displayed in the last
character position and is toggled using the +/- key
when data entry is active.
For an offset bearing, the label is displayed as B
and the data is a three-digit number indicating the
offset bearing, which has an allowable range of
001to 360 and is always referenced to true north.
Pressing ENT activates this change.
Y NNNN
or BNNN
W3 - Allows the pilot to enter either the offset
along track distance (for a Y offset) or the offset
