Sentry Plus ADS-B (And Much More) Debuts

The "multi-function" part? The Sentry Plus is also a carbon monoxide detector, a Wi-Fi router, a multi-constellation global positioning receiver, and an inflight track logger. It also has built-in AHRS, which supports synthetic vision emergency attitude on the iPad and a display of G-forces---yes, it's a G-meter, too.

While the Sentry Plus is designed to integrate with your iPad, the built-in display will provide real-time system status, as well as Carbon Monoxide conditions, with dangerous CO levels annunciated on the display. Additionally, the integrated flight data recorder with G meter, like what is found in many aerobatic airplanes, will keep you appraised of G Loads as they happen. And with its up to 18-hour battery life, the Plus is a tempting step-up product for current Stratus owners or those just getting into the ADS-B world.

Just its global positioning receiver might be reason enough for some to step up. The multi-constellation receiver is virtually jam-proof, according to the manufacturer, offering accuracy to within 1 meter. For backup purposes, if the US GPS is jammed, the built-in receiver will switch to the European Galileo satellite constellation without manual intervention.

The Sentry Plus, which goes for $799, is available at Sporty's Pilot Shop.
