Since last summer, GXRP has carried an Avidyne EX-500 MFD unit in its avionics stack. The MFD converses with the mothership across a radio data link to fetch weather and such info, and routinely transmits its position. Now Avidyne has added a new feature to the package: on-line flight tracking. People who receive a password from me can log on to a web site, and get a look at the position and planned track of the airplane, while still in the air. Soon they will be able to send/receive text messages to the flight. Cool cool cool.
