Drawing on the success of their popular Stratus Automatic Dependent Surveillance-Broadcast receiver, the team of Sporty’s, ForeFlight, and Appareo Systems on July 7 announced a new model—or two. The Stratus 1S and 2S are evolutions of the market’s most popular route to subscription-free traffic and weather in the cockpit.

Sporty’s John Zimmerman said the lure of a new release is always to add more features, but with these updates the team decided to make improvements behind the scenes to better performance and reliability. And by stripping out certain features, the new 1S retails for $549.

There are a number of differences between the two models. Most important are traffic and synthetic vision. The 2S has dual-band traffic and the attitude heading reference system capability to display ForeFlight’s synthetic vision. The 1S has only single-band traffic and no AHRS. (For airplanes without ADS-B Out, dual-band traffic capability will show aircraft transmitting on both ADS-B frequencies, whereas single-band only shows those transmitting on 978 MHz.) The 2S also includes a pressure sensor that enables a cabin alert system and pressure altitude display in ForeFlight.

Both have hardware and software updates that result in better cooling and better connectivity.

A little-used feature for most GA users is new Wi-Fi encryption. This enhancement is a window into ForeFlight’s growth with corporate, airline, and military users, none of whom want unauthorized users to be able to access the device.

The new 1S and 2S are available now at, and retail for $549 and $899, respectively.
