Carbon monoxide alarm

Carbon Monoxide Detector

A first for portable ADS-B receivers, Sentry provides a built-in carbon monoxide sensor and alerting system, with an audio and in-app alert when CO concentration reaches hazardous levels. The LED indicator also provides a visual indication of CO levels

Synthetic Vision

ForeFlight Synthetic Vision provides a backup glass cockpit on your iPad that can help you stay aware of your position and surroundings in normal and emergency operations. Combined with Sentry, Synthetic Vision provides super responsive pitch and bank in addition to terrain and obstacle depictions. Simple calibration supports mounting Sentry on the left window, dash, or right window.

12 Hour Battery Life

Sentry’s efficient power usage allows up to 12 hours of continuous operation on a single charge, providing non-stop situational awareness for the long haul. Recharges using included USB-C cable.

Integrated Weather Replay

With onboard memory supporting up to 30 minutes of FIS-B data, Sentry saves animated radar and other weather so data is available as soon as you connect. Turn off your iPad screen and save battery when not in use.

Fast & Reliable Mounting with Quick Release

Sentry’s quick release mechanism means you can attach and remove it in under a second. The popular RAM® suction cup mount ensures a long-lasting seal and high heat tolerance so you can leave it in the plane between flights.

Compact Form Factor

If you’ve got room for a deck of cards in your aircraft, you’ve got room for Sentry. Large enough to not get lost under the seat, yet small enough that it doesn’t block your view, and the internal battery makes charging simple and straightforward. Measures 2.25"w x 3.25"l x 1.25"d.

Easy Firmware Updates Through ForeFlight

Updating Sentry’s firmware is a non-issue thanks to fast over-the-air updates through ForeFlight. When an update is available, ForeFlight provides one-tap installation that finishes in seconds.

Essential Pilot Tools

Subscription-free weather

Sentry receives all the weather products transmitted by the FAA, including newer options like icing forecasts and cloud tops—and there is no monthly subscription for weather. As long as you’re in range of a ground station (usually by 500-1000 feet AGL), everything is regularly refreshed. ForeFlight makes it easy to overlay multiple weather graphics on your route of flight, so you can make informed decisions and stay safe.

Jam-resistant GPS

Sentry also includes a multi-constellation GPS receiver that is incredibly accurate and reliable. In addition to 1 meter accuracy, the built-in receiver will switch to the European Galileo satellite constellation if the US’s GPS system is jammed or unavailable for any reason. It’s a powerful bit of redundancy, and it’s all automatic.

AHRS for backup attitude

The built-in AHRS drives a real-time pitch and bank display in ForeFlight. If you subscribe to Synthetic Vision, you can even see a 3D view of the world, complete with airports, terrain, obstacles, and traffic. This is not intended for primary reference, but it’s a great backup, and it is also recorded for ForeFlight track log replay.

ADS-B traffic

Sentry has a dual band ADS-B receiver, so you’ll see traffic both directly from other aircraft equipped with ADS-B Out (air-to-air transmission) and from ground stations (TIS-B traffic broadcasts).
