 (12) The table below gives the conditions of display of the altitude information:
 -------------------------------------------------------------------------------| PARAMETERS | DISPLAY | |--------------------|--------------------------------------------------------| | Baro correction | - If standard altitude used (selected on FCU) : STD | | | cyan in a yellow box, flashing when actual altitude | | | is below transition altitude. | | | - If baro altitude used (selected on FCU) : QNH or QFE | | | (This last displayed in a white box ) white below | | | the correction value. | | | - The correction value is displayed in Hpa or inches | | | of Hg according to FCU selection (in cyan colour). | | | - The selected baro reference and the digital value | | | are both flashing when actual altitude is above | | | transition altitude. | |--------------------|--------------------------------------------------------| | Landing elevation | - brown ribbon on altitude scale when baro altitude | | (ground reference) | is used, landing elevation is valid and the | | | difference between landing elevation and actual | | | altitude is less than 570 ft. Moreover, landing | | | elevation is displayed only during flight phases | | | 7 and 8. | | Altitude digital | - Yellow when actual altitude is between the boundaries| | readout window | (sel alt. -250ft., sel alt. +250ft.). | | | - Pulsing in yellow when actual altitude is outside | | | the above interval, but gets closer to selected | | | altitude. | | | - Flashing in amber when actual altitude is outside | | | the above interval and the difference with selected | | | altitude increases. | |--------------------|--------------------------------------------------------| | Selected altitude | - Cyan if altitude is selected on FCU. | | | - Magenta if altitude constraint comes from FMGC. | | | When the value is within the boundaries (actual | | | altitude -575ft., actual altitude +575ft.), it is | | | boxed by the selected altitude symbol, in the same | | | color. | | | Out of these boundaries, the digital value is | | | displayed above or below the altitude scale according| | | to the difference with actual altitude. | | | Baro altitude is displayed in feet, standard altitude| | | is displayed in hundreds of feet. |
