10.1 Rear Seat Device (LXNAV V7D)
In two-seat gliders it is possible to install the LXNAV V7D rear seat device. The V7D looks
almost identical to the V7. In fact it runs on exactly the same software as on first seat
device.
The basic idea of two-seat configuration is that both devices work independently from each
other with the possibility of automatically exchanging various pieces of data (Loudness, Mc,
polar…).
10.1.1 Data Exchange
All data is exchanged between front and rear unit. LXNAV V7 also exchanges data with GPS
and PDA. Change of MC, Bal, Bugs, Volume, polar settings,... on PDA, will have also
influence on LXNAV V7. Same will happen also in opposite way.
