Detailed Operation
Text Display
FIS text messages are available on the text display and include METARs, TAFs, AIRMETs, SIGMETs, and TFRs.
Individual text messages are updated every five minutes and composed of four parts: message type, location,
time and message body.
Text Information Examples:
TYPE LOCATION TIME MESSAGE BODY
METAR KSLE Z METAR TEXT
METAR KMMV Z METAR TEXT
TAF KSLE Z TAF TEXT
The upper portion of the FIS Function page is used for displaying the contents of an individual FIS message
while the lower portion of the screen is used for categorization and sorting of different message types, such as
METARS, TAFs, SIGMETS, etc.
The lower portion of the screen is divided into three distinct columns to provide simple categorization of
received text messages. The columns are loosely defined as message type, location and time stamp to handle
the most common type of FIS up-link data.
The different message types and data content are fully controlled by the ground broadcast systems. The air-
borne system will automatically display any message type that is received.
US and Canadian text METARs, text and graphical TAFs are available at the same time when subscribed to
both US and Canadian products. US and Canadian METARs and TAFs use the same format as described below.
Selecting Text Data
Green colored Selection Pointers above the smart keys can be used to select an alternate message for display.
The selected line in the section above the smart keys is noted by a green circle with an “I” inside. The pilot is
able to move the green Selection Pointer within the lower portion of the page to select the desired category,
location and time that is of interest with the use of the arrow keys.
