SYSTEMS AND METHODS FOR DETECTING AND ALERTING MIS-SETTING OF BAROMETRIC ALTIMETER SETTING DURING A TRANSITION ALTITUDE

Systems and methods for producing an advisory if barometric altitude transition setting needs adjusting in an aircraft. In one embodiment, the method determines transition altitude, receives an uncorrected altitude, compares the uncorrected altitude to the transition altitude and to corrected altitude, and outputs a barometric altitude transition setting advisory based on the comparison between the uncorrected altitude and the transition altitude. The comparison determines if the uncorrected altitude is greater than the determined transition altitude and the advisory is output if the uncorrected altitude is determined to be greater than the transition altitude and the uncorrected altitude differs from the corrected altitude by a threshold amount. A delay is provided between the comparison of the uncorrected altitude to the transition altitude and the comparison between the uncorrected altitude and the corrected altitude.
