ED Decision 2018/002/R
- 3.2 Specific
None.
3.2.1 Failure Condition Classification
See CS-ETSO, Subpart A, paragraph 2.4.
The failure condition classification appropriate for the equipment will depend on the intended use of the equipment in a specific aircraft. The loss of function and malfunction failure condition classification for which the equipment is designed should be documented, considering also obstructions to the pilot's field of view resulting from potential malfunction conditions.
