Ariane 5 Case Study
- Variable exceeds it's range...
e) At 36.7 seconds after H0 (approx. 30 seconds after lift-off) the computer within the
back-up inertial reference system, which was working on stand-by for guidance and
attitude control, became inoperative. This was caused by an internal variable related to the
horizontal velocity of the launcher exceeding a limit which existed in the software of this
computer.
