View list of Compatible Apps.


Open ADS-B ModeNEW
Stratus 3 can be configured to work with other popular flight apps using the industry-standard GDL 90 protocol by enabling Open ADS-B Mode.

Smart WiFiNEW
Allows you to use your 3G/4G LTE cellular internet connection on your iPhone/iPad without needing to disconnect from your Stratus.

Auto Shut-offNEW
To preserve battery, Stratus 3 automatically powers down after flight by detecting when it’s idle or at less than a 3D GPS lock.

8-Hour Battery
Even with all these features, Stratus remains totally wireless. With its 8-hour battery life, you can fly all day without bringing along a charging cable. Just turn on Stratus and go flying.

Subscription-free in-flight weather
View in-flight weather on your iPad, including NEXRAD radar, METARs, TAFs, TFRs, AIRMETs, SIGMETs, NOTAMs and more. And still no subscription fees—ever.

Built-in AHRS
Stratus 3 includes a complete Attitude Heading Reference System (AHRS) for supplemental attitude information in the cockpit. It aligns itself automatically, so you can just turn it on and fly. Pilots who use ForeFlight’s Synthetic Vision will experience a visually stunning and high-performance hazard awareness capability.

Note: AHRS data provided by Stratus should be used for supplemental purposes only. Stratus is not certified for IFR operations.

Dual-band ADS-B Traffic
Stratus 3 includes a dual-band (978 MHz and 1090 MHz) ADS-B receiver and displays traffic information right in your flight app. See your aircraft’s relative altitude, climb/descent rate and projected track.
