After the maneuver, all instruments and products will resume nominal production and distribution.


All ABI channels will experience navigation and product quality degradation for a period of time up to 30 minutes due to the Kalman filter reset.  There is no back up date for the yaw flip. It will be conducted during a critical weather day.
