Stratus 4: Frequently Asked Questions:

1. Which aviation apps are compatible with Stratus 4? Stratus 4 features an "open" architecture, making it compatible with nearly every major aviation EFB on both iOS and Android. This includes ForeFlight, Garmin Pilot, Stratus Insight, FlyQ, WingX Pro, and FltPlan Go.
2. How do I find my Stratus 4 if I leave it behind at the airport? The Stratus 4 is the first ADS-B receiver to include Apple Find My™ integration. You can register the device to your Apple account and track its location on a map from your iPhone or iPad, just like an AirTag.
3. Is the battery really replaceable by the pilot? Yes. Unlike previous generations or competing models, the Stratus 4 features a user-replaceable battery. You can swap it out yourself without any tools, avoiding expensive factory servicing or downtime.
4. Does Stratus 4 require a monthly subscription? No. Stratus 4 receives subscription-free FIS-B weather and ADS-B traffic information from ground-based towers. There are no recurring fees to access NEXRAD, METARs, TAFs, or traffic data.
5. Can I use the Stratus 4 outside of the United States? While GPS and AHRS functions work globally, ADS-B weather information is currently only available within the United States, as it relies on UAT ground stations. Traffic can still be received air-to-air via the dual-band receiver.
6. Does it work with Garmin Pilot? Absolutely. Stratus 4 is now considered one of the best portable receivers for Garmin Pilot users. It provides reliable GPS, weather, and traffic data, and even allows you to view receiver health directly in the app’s status section.
7. How do I dim the screen for night flying? You can adjust the brightness of the full-color touch screen through the device’s main Settings menu or via the connected app (such as the Stratus Horizon Pro app) to ensure it doesn't interfere with your night vision.
8. Can more than one device connect to a single Stratus 4? Yes. Multiple iPads or iPhones can connect to the Stratus 4’s built-in Wi-Fi network simultaneously, allowing both the pilot and co-pilot to view the same weather and traffic data.
9. Does the Stratus 4 make me "ADS-B Out" compliant? No. Stratus 4 is an ADS-B In receiver. It allows you to receive data but does not fulfill the FAA’s requirement to transmit your position. You still need a certified ADS-B Out transponder for 2020 mandate compliance.
10. How should I mount the Stratus 4 for the best AHRS performance? For the AHRS and synthetic vision to work accurately, the device should be mounted securely and aligned with the larger side pointing toward the front of the aircraft. It can be placed on the dash or used with the included window suction cup mount.
