 **ON A/C ALL
 The altitude scale presents the A/C actual altitude according to a baro setting reference. Different displays are presented depending on this reference (standard or baro corrected). The altitude value is transmitted by the ADIRU on label 203 (standard altitude) and on label 204 (baro altitude) on CAPT side or on label 220 (baro altitude) on F/O side.

 item (a) The altitude indication is provided by means of a tape moving up and down with respect to a window within which the A/C actual altitude is displayed. The tape of the scale is graduated every 100 ft. and digital values are displayed every 500 ft. in hundreds. The A/C actual altitude is provided by a counter located at the middle of the scale in which the actual value is displayed in green digits. The hundreds of feet are written in a large size whereas the tens and units are displayed by a drum operating as a classical mechanical altimeter. Small white marks are positioned in front of every number on the tape.
