## Discrepancy

DOES NOT MAINTAIN THE PRESELECTED LOCAL AND REVERTS BACK TO 22XX.  IN THE EVENT OF A ROLL BACK OR MISCOMPARE, THERE IS NO AURAL WARNING OR CAS MESSAGE TO THE CREW.  THE ONLY INDICATION IS A SMALL YELLOW LINE BELOW THE BAROMETRIC PRESSURE SETTING ON THE PFD, WHICH IN TURN, IF OVERLOOKED, COULD RESULT IN ALTITUDE MISCOMPARE.  THIS COULD BECOME A SAFETY ISSUE IF THE CREW DOES NOT VALIDATE THE SETTING AFTER GENERATOR SELECTION OR BEFORE TAKEOFF. THIS ROLL BACK ISSUE HAS BEEN REPORTED BY 7 OTHER OPERATOR ARE CURRENTLY INVESTIGATING THE CAUSE OF THIS SITUATION AND WE WILL KEEP YOU INFORMED AS MORE DETAILS BECOME AVAILABLE.
