Note   Sufficient time data is required to permit determination of the relationship between recorded information and Universal Coordinated Time.

4 Minimum performance standard — signal characteristic
       All parameters of the FDRIU must be sampled, conditioned, and digitised or reformatted in such a manner as to meet ARINC 717-15 standard signal characteristic.

5 Minimum performance standard — failure condition classification minor
                   The FDRIU must have a design assurance level commensurate with the failure condition classification of "minor".
Note   The concept of failure condition classification is described in the appropriate certification specification guidance material. For example, EASA AMC 25.1309.

6 Minimum performance standard — environmental test
       The FDRIU must be tested in accordance with the test conditions mentioned in RTCA/DO-160F.

7 Minimum performance standard — software
       Software for the FDRIU must be developed in accordance with RTCA/DO‑178C to Level D as defined in section 2.3.3 of RTCA/DO-178C.

8 Minimum performance standard — electronic hardware qualification
       The electronic hardware for the FDRIU that is complex as described in section 1.6 of RTCA/DO-254 must be developed in accordance with RTCA/DO-254 to Level D as defined in Table 2‑1 of RTCA/DO-254.

9 Minimum performance standard — fire protection
       The materials used in the manufacture of the FDRIU, other than small parts that would not contribute significantly to the propagation of fire, must be self‑extinguishing in the event of fire and meet the requirements of Category C of section 26 of RTCA/DO-160F.

10 Minimum performance standard — marking
       (1)Subject to subclause (2), each component of the FDRIU must be permanently and
