A:
Auto mode. Traffic will be displayed at the selected map range only
when alerting traffic is present, except that the map range will auto-scale to an
appropriate range to show the traffic on-screen.
Manual (M) or Auto (A) modes do not display non-alerting traffic.
Add following text if Data Link Weather is installed:
The SN3500 can display two types of weather information, precipitation and
lightning. Lightning may be displayed from two independent sources, WX-500
Stormscope
or a FIS-B data link receiver. Both sources of lightning may be
displayed simultaneously.
The SN3500 WX pushbutton selects the type weather to be displayed:
PL:
Precipitation & Lightning
P:
Precipitation only
L:
Lightning only
The ‘M’ pushbutton followed by the WX pushbutton selects the lightning display
data source, either WX500, WSI, or both. The number to the right of the WX
annunciation displays the time in minutes since the last FIS-B precipitation data
was received from the data link receiver.
Weather graphics depicted on the SN3500 data link weather display may differ
significantly from the on-board weather radar or from out of the cockpit
observations for one or more of the following reasons.
Vertical strata information is not provided by the FIS-B weather service.
The FIS-B weather data originates from NEXRAD ground based weather
radar observations that include weather measurements up to 30,000 feet
above the radar facility. The on-board weather radar is measuring returns
relative to the current flight level.
The FIS-B weather display is not exactly real time. Under certain
circumstances the time from when the NEXRAD radar observations were
made to when the data is displayed on the SN3500 can be as high as 40
minutes. During this time the position of the weather may have
significantly changed or moved relative to the aircraft position.
The graphic representation of precipitation is predicated on the level of
reflected energy from moisture in the air mass (the more moisture in the air
mass, the higher level of energy returned to the radar antenna). This may
result in graphic presentation of precipitation on the SN3500 display when
no visible moisture can be seen.
Virga precipitation: the precipitation may be at a higher flight level and
evaporating before reaching the current aircraft flight level.
