-------------------------------------------------------------------------------| FLAGS | DISPLAY | |--------------------|--------------------------------------------------------| | ATT | Red flag replacing the whole attitude display when | | | attitude is invalid, flashing during 2s then steady. | | | This flag disappears when DMC is supplied again with | | | healthy pitch and roll data. | |--------------------|--------------------------------------------------------| | FPV | Red flag under initial position of horizon line (has a | | | steady position and does not follow pitch and roll | | | variations). It is displayed in TRK/FPA mode when | | | attitude is valid but drift angle or flight path angle | | | are not valid. | |--------------------|--------------------------------------------------------| | FD | Red flag in left upper corner of upper sector of pitch | | | scale. It is displayed when FD pushbutton switch light | | | is on on FCU, attitude is valid and not excessive, and | | | besides, both FMGC are seen invalid or both FD are | | | disengaged. | | | This flag flashes during 9s then is steady. | |--------------------|--------------------------------------------------------| | CHECK ATT | Amber message under upper limit of upper sector of | | | pitch scale. It is displayed when there is attitude | | | discrepancy between CAPT and F/O PFD or discrepancy | | | between input and displayed pitch or roll. | | | This flag flashes during 9s then is steady. | |--------------------|--------------------------------------------------------| | SI | Red flag instead of lateral acceleration index when | | | lateral acceleration is invalid on the ground or | | | estimated side slip and lateral acceleration are | | | invalid in flight. | |--------------------|--------------------------------------------------------| | RA | Red flag on the lower sector when both radio altimeters| | | are invalid, altitude is not excessive and the aircraft| | | is in clean configuration. | |--------------------|--------------------------------------------------------| | DH | Amber message in lower part of attitude scale when | | | attitude is not excessive, DH and RA are both valid | | | and DH>RA. | | | This flag flashes during 3s then is steady. |
