The example shows the altitude data output from the local ADIRU.
The digital signal can also be the bit data from a digital word. These are the data that shows on this page:
- LRU that the discrete word is from
- Discrete word label
- Word bits and name
-Bit values for systems A and B. The example shows the discrete word 270 from the autothrottle (A/T). NOTE: The A/T computer is deactivated so the A/T system is not
functional for this airplane.
