Is there a means to leave the transponder on? Ground radar is being
tested at
Providence now, and is likely going to be showing up at air carrier
airports
around the country soon requires the transponder on for any movement on
the
ground.

The G-1000 has a "squitter," (Is that the right term? Someone help me out
here...) a device that replies to Mode S queries from radar while on the
ground. It can also be manually switched to Mode A or C on the ground by
pushing a single button.
