Deviate from RTCA DO-283A Appendix C section C.2.1 by using a different weighting-algorithm to select or exclude VOR stations, and secured with reasonableness checks.

Deviates from RTCA DO-283A Appendix C section C.2.2 by using a different algorithm to determine position from multiple (more than two) DME, and secured with reasonableness checks.

Deviates from RTCA DO-283A Appendix H section H.2.4.4.3 by using a different vertical guidance compatible of the vertical constraints.

Deviates from RTCA DO-283A Appendix H section H.2.7 by alerting 15 seconds instead of the minimum 30 seconds before the required vertical path change.

Deviate from RTCA/DO-229D 2.2.3.3.1 and provide the deviations relative to the first approach leg instead of the FAF.

Clarification on the limited validity of equation (A-22) and (A-22a) proposed by DO-229(A,B,C,D) for the ionospheric pierce point location computation and provision of a formula which does not have that limitation.

Deviate from ETSO‐C30c by not marking the minimum lamp candle power or lamp part number for lights using non‐replaceable light‐emitting component(s).

Deviate from ETSO-C80, Appendix 1, § 4.2.a, substituting the test fuel MIL-S-3136, Type III, with fuel Jet A1 for tests in the paragraphs: §7 Slosh, §8 Stand test, §10 Fluid resistance of exterior surface, and §17 Low temperature leakage.

Deviates from ETSO-C80, Appendix 1, § 7 Slosh test, specifically from § 7.1.15, performing slosh test without including water and dye in the test fluid as required by the test procedure.

Deviate from ETSO-C80, Appendix 1, § 7.1.3 performing slosh test at room temperature instead of at 135°±10° F.

Deviate from ETSO-C80, Appendix 1, § 11.0 Permeability, specifically from §11.1.2 Test Procedure, carrying out permeability testing at a relative humidity (RH) level of 50 +/- 5% instead of 40 +/- 5%.

Deviate from ED‐73E by not performing explosion test for these equipment limited to installation in nonexplosive atmosphere.
