2.1.9.1.2 LLWASAAD
Parameters Units
1. Wind direction “D” degrees
2. Wind speed “S” knots
3. Gust knots
This function calculates a gust string that displays centerfield wind data at the
bottom of the AAD.
The string format input determines the order and content of the gust string
output e.g. a string format of the form CF<DIR><SPD><G><GUST> would
produce the following centerfield wind display (<G> adds the character “G” if
a gust is currently valid):
Wind direction – Average wind speed – Wind gust speed
The gust threshold is a value set above the average wind speed. When the
calculated “peak” wind exceeds the average by more than the threshold, then
a gust value is displayed on the AAD.
2.1.10 Archiving / Playback
The Archiver application is used to independently store data from the remote
MetConsole servers. Two optional features are often installed with the
Archiver to provide a full archive & replay system:
• Media backup
• Data replay
One of a number of media backup options is available (i.e. Tape, optical disk,
removable disk drive).
The archiver application normally runs in the Windows task bar, and as such
is usually available from the bottom right of the screen (depending on any
personalised settings that may have been set up).
The displayed icon may change depending on the state of the archiver:
The archiver is connected to the hot server, and idle.
