What software development requirements apply to engine-driven direct current generators/starter-generators that include a digital computer?

If the generator/starter-generator and associated voltage regulators include a digital computer, software development must comply with CS-ETSO, Subpart A, paragraph 2.2.

What specific marking information is required in addition to the general marking requirements for ETSO-C56b articles?

In addition to general marking per CS-ETSO Subpart A paragraph 1.2, the article must indicate: (1) whether it is a D.C. generator or D.C. starter-generator; (2) nominal power output (electrical voltage and watts); (3) mechanical power input requirements (pad requirements).

What environmental standard applies to engine-driven direct current generators/starter-generators under ETSO-C56b?

The environmental standard is specified in CS-ETSO, Subpart A, paragraph 2.1.

What airborne electronic hardware requirements apply under ETSO-C56b?

Airborne electronic hardware must comply with CS-ETSO, Subpart A, paragraph 2.3.

ETSO-C56b A1

Q: Which articles are subject to the requirements of ETSO-C56b?
