To request a NexRAD weather picture, press the WX 

key and select 

 in the menu.  If the current 

request settings are correct, simply press the Enter 

key. 

If you are connected to the 

satellite transceiver, the request 

will be sent to an ORBCOMM 

satellite and relayed to Echo Flight 

where a compressed data packet 

of weather will be sent back to you 

via satellite.  The satellite status 

indicator shows the current state 

of this process.  (See section 2.5).  

The NexRad layer will 

automatically display on the map when received.  This layer can 

be toggled on and off by pressing Enter from the map. 

: 

In Demo mode the NexRAD process is simulated.

 

Select the 

 option to set the diameter of the weather 

request area.  Use the Left and Right keys to decrease or 

increase the range from 75 and 500 Nm in 25 Nm increments.  In 

order to optimize your request, select only the range you require. 

(i.e. the distance to the next Waypoint). Transaction times can 

increase with larger requests.  The server may also be able to 

provide higher definition pictures if smaller request ranges are 

used. 

There are two NexRAD request modes, 360 and Ahead. The 360 

mode is for those times when you may want a full 360-degree 

NexRAD picture centered on your current position.  Remember 

that in 360 mode the request range is roughly half the forward 

distance.  The Ahead mode extrapolates the request from your 

current GPS location toward your target Waypoint so that most of 

the picture will be situated ahead of you, with only a portion 

behind you. The Ahead mode does not require you to be flying 

toward the requested Waypoint.
