A Stationary Front is a front with very little horizontal movement. The line
alternates with orange and blue sections which point in opposite directions to
symbolize little movement.
An Occluded Front is where a cold front has overtaken and merged with a
warm front. The line alternates with the blue triangle and orange half moon sym-
bols on the same side of the line pointing in the direction the front is moving.
Surface Data Viewing Range
The Surface Data Viewing Range option allows you to select the map range
where at and below that value Surface Data weather products will be shown on
the selected MFD Wx Data Link Map page (1, 2, or 3). When Off is selected,
Surface Data will not be shown. Where a value (such as 150 NM) is selected,
Surface data will be shown at map ranges of the selected value (150 NM) and
lower.

the displayed value. The next option will be highlighted.
3) Press the small MFD knob to cancel selection or to end editing and return to
the previously viewed page or turn the large MFD knob to the next option.

and City Forecast weather products will appear on the selected MFD Wx

current, 12, 24, 36, and 48 hours. The interval is selected by pressing the
