ADS-B traffic and weather on ForeFlight with Sentry

Don’t Settle for a Slice - Get the Full Weather Picture

Knowing what’s around you is just as important as knowing what’s in front of you.

With Sentry you can access subscription-free FIS-B weather & data. Display animated regional and CONUS NEXRAD, METARs, TAFs, AIR/SIGMETs, PIREPs, textual winds and temps aloft, TFRs, NOTAMs, and SUA information on ForeFlight Mobile.

 
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.

Sometimes it’s as Simple as Knowing Where to Look

Get help in “seeing and avoiding” with dynamic traffic display in ForeFlight. Receive air-to-air traffic information from ADS-B Out equipped aircraft and rebroadcast traffic information from FAA ground towers (ADS-R / TIS-B).

Note that if your aircraft is not ADS-B Out equipped, your view of traffic may be limited.

Traffic Traffic
Inflight Traffic Alerts

ForeFlight doesn’t just show you where the traffic is, it tells you. Visual and audio alerts provide the distance, direction, and relative altitude of ADS-B traffic targets.

The Standard in Reliable GPS Technology

Pilotage meets the 21st century with Sentry’s highly-accurate WAAS GPS. See your aircraft position on ForeFlight’s moving map display and innovative Plates on Map feature. Sentry supports four GNSS systems (WAAS GPS, Galileo, GLONASS, and BeiDu), and can track three constellations concurrently for redundant location tracking. View a variety of inflight data, including ground speed, altitude, ETE, distance to destination, and more.

Built-In AHRS for Backup Attitude

Sentry’s Attitude Heading Reference System (AHRS) provides a real-time depiction of your aircraft’s pitch and bank in ForeFlight. Flexible calibration options allow you to get accurate AHRS data no matter where you mount Sentry in your aircraft.

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.

12 Hour Battery Life for Extended Operation

Sentry’s efficient power usage allows 12 hours of continuous operation on a single charge, providing non-stop situational awareness for the long haul.

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.

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.

LED Auto-Dimming Protects Your Night Vision

Sentry has a light sensor to detect the ambient light level and automatically adjust its LED brightness accordingly. You can also disable this setting to manually set the brightness.

Inflight Connectivity for Pilots and Passengers

Sentry’s integrated Wi-Fi network supports up to 5 devices.

Use ForeFlight’s Cockpit Sharing feature to quickly and easily share routes between all devices on Sentry’s network - perfect for your co-pilot and passengers to follow along as extra eyes on traffic and weather.
