Smart Key Function

The fourth “smart” key performs special functions within

the FIS Function:

When the Selection Pointer is located in the first of the

three columns, the fourth “smart” key displays the label

“Clear”. When pressed, all messages for the currently

selected category will be flushed from the MX20. This

feature can be used to clear old, bad or corrupted data

received over the data link.

When the Selection Pointer is in the center-most column,

the fourth “smart” key displays the label “Sort.” See below

for how the sort option works.

When the Selection Pointer is in the right most column,

the fourth “smart” key displays the label “View.” When

pressed, the currently viewed message is presented in a

full screen mode. This feature provides a mechanism to

view large textual messages that do not fit within the

upper half of the display area. Some messgaes may be

longer than can be displayed in the full screen mode.

These are indicated by a small arrow at the bottom of the

area. Press the arrow keys to scroll the information.

Viewing Text TAFs

Pressing the “View” key when highlighting TAFs will

display a full screen with the text TAF at the top and a

graphic representation in the lower portion of the screen.

The Time column includes both date and time. The

METARs column displays active METAR information.

The Prev column displays prevailing conditions. The

Tempo column displays termporary conditions. The Prob

column displays probable conditions. Press the arrow keys
