ABOUT AHRS
ForeFlight Mobile users can use Stratus 2S for backup AHRS (attitude,
heading, and reference system) to enhance situational awareness. For
the most accurate AHRS information, ensure the receiver is mounted
parallel with the centerline of the aircraft running front to back, and the
logo and LEDs on the device should face opposite of the direction of
ight.
Refer to the graphic on the bottom of the receiver for the correct
mounting alignment with the aircraft.
NOTE: AHRS and Synthetic Vision data provided by the receiver and
ForeFlight Mobile should be used for supplemental purposes only.
CALIBRATION
Stratus 2S is automatically calibrated to the position in which it is
mounted a few seconds after being powered on. Do not power on
Stratus 2S until it has been mounted.
If Stratus 2S is moved after being powered on, it can also be re-
calibrated to straight and level in ForeFlight Mobile. If your aircraft isn’t
straight and level, the alignment can be manually adjusted in the app.
