Jeppesen FliteDeck 3 - Manual (Page 200)

Satellite Weather
203
Many pilots who must fly multiple legs and do not want extra clutter in the cockpit
connect to their weather receiver before takeoff. They then ensure they are getting
weather data, allow it to cache for approximately twenty minutes, or until all the
weather products display in JeppView FliteDeck, then disconnect the receiver and use
the cached data while flying. When they reach the next destination, they repeat the
process to get up-to-date information.
There are a few things to keep in mind if using this process to view weather in
JeppView FliteDeck:
• Because you are not seeing live weather from a satellite feed, the rate of
error is increased slightly. You are at your own risk when viewing cached data
from your hard drive. Even though the data is correct between the valid time
and expired time, you are not receiving constant updated information. Having
the correct time on your computer ensures that the data that is to expire
actually is removed from the FliteDeck display when it is supposed to.
• Make sure your computer clock is set to the correct time and time zone at all
times.
• View the weather legends to display the age of the data. When you first
connect to the weather receiver and start to display weather data in
FliteDeck, check the age of the data before disconnecting. The more recent
the data, the longer you might be able to display weather from the cache
directory. The weather data expires at various times depending on the
weather product. Some weather products are valid for many hours (such as
freezing levels and winds), and some data might expire in an hour (METARs).
Currently, there is no access within JeppView FliteDeck to display the times that the
weather products are to expire.
Advanced Configuration of the Jeppesen Weather Controller
This topic describes the following startup options of the Jeppesen Weather Controller
(JWC):
• Automatic
• Manual
• Disabling JWC
NOTE
You must be logged on as an administrator or a member of the
Administrators group in order to complete the procedures described
below. If your computer is connected to a network, network policy
settings might also prevent you from completing these procedures.
Automatic Startup
By default, every time your computer starts, JWC automatically initializes XmLink to
collect weather data from your receiver. If a receiver is not connected, the
XM2Nr
Error dialog box appears. The benefit of having JWC and XmLink start automatically
at startup is that weather data can be collected immediately when a weather receiver
is connected.
