The fast-locking, WAAS GPS aboard Stratus enables features like geo-referenced plates, moving map, and own-ship position on taxi diagrams. With WAAS, you will frequently see 1 meter accuracy or better.


When connected to Stratus, ForeFlight Mobile can display dual band (978 MHz and 1090 MHz) air-to-air, ADS-R, and TIS-B traffic. ForeFlight’s traffic system supports mixed-mode display of both directional and nondirectional targets.

Stratus is a top value.

Backup Attitude

Stratus 3 includes a complete Attitude Heading Reference System (AHRS) for backup attitude information in the cockpit. It aligns itself automatically, so you can just turn it on and fly. For Synthetic Vision subscribers, attitude information is displayed on top of terrain. Works in portrait or landscape, split screen and full screen.
