Synthetic vision to find runways
ForeFlight's synthetic vision display is a pilot favorite. Its incredibly lifelike display of terrain and obstacles, combined with the responsive pitch and roll indications from the built-in Stratus AHRS, create a powerful situational awareness tool. But SV is good for more than just avoiding towers. We've found it to be invaluable for finding the runway on a hazy summer day, or knowing how to enter the pattern at a new airport. ForeFlight's realistic runway depiction, complete with runway numbers, is a confidence booster.
Getting up-to-date weather information is critical, but leaving your iPad screen on full time will run down you battery in a hurry. That's why Stratus Replay is so handy: when you're not using your iPad, turn off the screen and save battery life. When you turn it back on, Stratus automatically checks for any weather you may have missed while the screen was off, then sends it to your iPad. You preserve battery life but never miss a radar update.
All-Day battery life
All pilots have enough wires in the cockpit already; Stratus won't add to that mess. You can mount it out of the way and fly all day on a single battery charge (over 8 hours). This makes it perfectly suited for renters or flying club members, since it can easily move back and forth between airplanes. The built-in battery also makes Stratus a great backup, since it's completely self-contained.
Pressure altitude warnings
If you fly a pressurized airplane, or a turbocharged airplane that requires regular oxygen use, keeping track of your cabin altitude is literally a life-or-death matter. Stratus 2S makes a great backup to your panel equipment, with its built-in pressure altitude sensor. You'll see a pop-up reminder as the cabin passes through 12,000 and 25,000 feet. If you're flying a pressurized airplane, you should never see either warning, so it's an important alert that something may be wrong. If you fly an unpressurized airplane, these warnings are a good reminder to use oxygen and check that it's working properly.
Auto AHRS calibration
Backup attitude and synthetic vision are some of the most popular features of Stratus, and one reason is that the built-in AHRS just works. For most aircraft, no manual calibration is required - just mount Stratus and turn it on. As you taxi out, Stratus will automatically calibrate, so the unit does not have to be level. If you do need to fine tune the pitch or bank indications, it's easy to do this right in ForeFlight.
Flight data recording
Want to make your flying more precise? Use Stratus's automatic flight data recorder to log your flights, then replay those flights in Google Earth or CloudAhoy. You'll be able to see your ground track, altitude and even the attitude of the aircraft. It's great for reviewing instrument approaches, steep turns or ground reference maneuvers. Stratus is constantly recording your flight; just upload the recordings to ForeFlight after the flight.
Easy firmware updates
Stratus is never standing still. Appareo releases updates from time to time that add new features (like flight data recording), fix bugs or improve performance. Unlike some other electronics, updating Stratus is fast and easy because it's deeply integrated with ForeFlight. Each firmware update is automatically downloaded as part of a ForFlight app update. Just connect your iPad to Stratus's WiFi network, go to the Devices page and tap Update.
turn on when powered mode
For aircraft owners and homebuilders, Stratus can be connected to the aircraft's electrical system for full-time power. In some cases, though, the Stratus device may not be within reach of the pilot. This exact scenario is why Appareo and ForeFlight created "Turn on when powered" mode. When this is selected (from the Stratus Status menu), Stratus will automatically turn on when the master switch comes on and it receives power. It will automatically turn off when the master switch is turned off.
But what about an electrical failure, when you would want the Stratus to stay on and use its AHRS for backup? Appareo and ForeFlight thought of that too: if Stratus detects it is moving faster than 5 knots, it will stay on and run off its internal battery. This can be overridden by pressing the power button. This is a great feature for remote-mounting Stratus.
ADS-B Out system checks
If you're flying with an ADS-B Out transponder in your aircraft (like a Garmin GDL 88 or GTX 330ES), Stratus can even show you complete ADS-B system performance information. Tap on the Stratus Status menu, then Ownship ADS-B Out. You'll see your N number, ICAO address, GPS information and all kinds of other numbers. You don't have to know what it all means, but if you see green letters, you're good. It's a fast and easy way to make sure your ADS-B Out avionics are set up properly.
