ForeFlight Launches Sentry Plus ADS-B Receiver


ForeFlight is expanding its ADS-B product suite with the introduction of its new Sentry Plus portable ADS-B receiver. Device features include ADS-B In weather and traffic, WAAS GPS, carbon monoxide (CO) monitoring and alerting and AHRS pitch and bank. The Sentry Plus also offers a 1.3-inch OLED screen, G-load meter, high-performance flight data recorder and 18-hour battery life.

“We continue to expand the Sentry family of affordable ADS-B products with the most advanced portable receiver yet,” said ForeFlight President Tim Schuetze. “Sentry Plus combines the best of previous devices with new innovations to make flying and logging even easier—for every kind of pilot. We’re proud to offer the only device on the market combining so many powerful features in such a compact and affordable device.”

According to the company, Sentry Plus’ antennas are optimized for concurrent UAT and European FLARM reception. The device was developed in collaboration with and is manufactured by uAvionix. Unit price for the Sentry Plus is $799.

  1. FLARM may be of European origin but there are many FLARM-equipped gliders flying in the US as well. It’s becoming more and more common.

  2. I purchased the Sentry with CO detection (07/27/2020) and it is always going into false alarms. It was a problem right out of the box and continues to this day. I contacted Foreflight and then the manufacturer uAvionix for support. They requested I return the unit for recalibration which I did. The false negatives still persist. I also have problems with this unit periodically disconnecting from the iPad. I upgraded from the Sportys Stratus and I wish I hadn’t. Hopefully this version works better than the previous version.

  3. uAvionix has, or had a battery powered small unit that was In and Out. Was only about $600, but not legal in US. FCC wouldn’t approve it although FAA the time didn’t care. It could not be used to satisfy the ADS-B airspace requirements though. However, a great safety advantage for letting other aircraft see me in my non electric Aeronca. I used it, “just testing only” until I sold my Aeronca.

  4. I am sure not the only one not using Fore Flight. Between them jacking up the rates and only running Apple based platforms, I have no need for them or their products. I was given lip service too many times from them at the meetings I attended. I can do with their smug attitudes and arrogance as well.

  5. Wow, FF not popular on this site.

    I’m curious if anyone in the alphabets has ever pointed out the popularity of portable units and that it’s likely proof that the certification system is counterproductive.

    • The reason ADSB out has to be certified is that ATC and everyone else in the air is depending on YOUR ADSB out to provide accurate and reliable position reports. ADSB in does not have to be certified because if your unit screws up it’s just on you.

      • Andy, that’s all well and good, but it’s not just ADSB out, which obviously has to have the antennas tested. It’s everything.

        The price ratio of certified to not certified is stupid high. Way more than is explained by quality or fire safety. The likely result is that owners are accepting reduced functionality by not upgrading their aircraft, and reduced safety by using portables.

        If the juice isn’t worth the squeeze, the regulation is likely causing accidents because the aircraft are flying around without equipment.

        Let’s look at some new widget. Hypothetically, the Widget could save 1 fatal accident per million hours. OTOH, a non certified Widget might cause a fatality at .001 per million. Certified Widgets maybe prevent the .001 fatality, but cost so much that almost no one uses them.

        Conscientious regulators would look into what’s causing the cost increase of the certified equipment and adjust it. There was some movement on this a few years ago with glass cockpits that had become popular in experimental aircraft and putting them in certified planes. Sport Aircraft use ATSM standards, but are limited to very light, slow planes.

        The industry is dying, something needs to give.

        • The industry has been dying ever since I have been part of it and that is over 30 years, nothing new there. I use to be on the band wagon that it was due to over regulation but as it turns out that is simply not true. People are not inspired by the prestige it suggested as they once were. Maybe the new Top Gun movie will provide some new blood but I doubt it will provide much. I doubt anything “needs to give” it just simply has found its current equilibrium.

  6. No thanks. The Stratux I built for about $200 in parts from Amazon is still going strong after five years of use.
