Detected malfunctions shall be annunciated and the malfunctioning display elements removed. \[Issue: CS-AWO/2] IR · AWO.A.EFVS.112 — CS-AWO · ED Decision 2022/007/R · CS-AWO Easy Access Rules · EAR revision 14 Aug 2026 AMC Acceptable means of compliance ## AMC AWO.A.EFVS.112 EFVS documentation The following minimum information should be provided in the AFM: \- (a) the approved limits established as a result of consideration of any other factor that the certification has shown to be appropriate; \- (b) the normal and abnormal procedures, including airspeeds; \- (c) the minimum required equipment; \- (d) any additional aeroplane performance limitations; \- (e) if appropriate, the type of approaches and the xLS navigation means (facilities external to the aircraft) and associated limitations (if any) which have been used as the basis for certification; \- (f) any related limitations and/or assumptions on the runway or aerodrome conditions that are affected by the use of the EFVS; for EFVS-L, this should also consider: - (1) runway elevation, - (2) approach path slope, - (3) touchdown zone slope, - (4) ground profile under the approach path; \- (g) the type and mode of operation/configuration of the approach lights (i.e. LED or incandescent) that have been used or assumed during the certification demonstration of the EFVS; \- (h) the demonstrated performance in accordance with CS AWO.A.EFVS.109; \- (i) wind speed limitations that are affected by the use of the EFVS; \- (j) any applicable assumptions that have been made during the certification demonstration of the EFVS. \[Issue: CS-AWO/2] Appendix 1 to the AMC to Section 3 of Subpart A EFVS compliance The following is a non-exhaustive list of certification specification in CS-25 that could be affected by an EFVS installation. Applicants for normal-category aeroplanes (CS-23) can use the list below to establish whether the equivalent aspects in CS-23 are affected and address them accordingly. Note: As of Amendment 5 to CS-23, the referenced CS-23 requirement numbers are reflected in the AMC to CS-23. | Certification specification | Description | | --------------------------- | ----------------------- | | 25.251 | Vibration and buffeting | | 25.301 | Loads | | 25.303 | Factor of safety | ED Decision 2022/007/R ED Decision 2022/007/R Easy Access Rules for All-Weather Operations (CS-AWO) | Certification specification | Description | | --------------------------- | --------------------------------------------------------- | | 25.307 | Proof of structure | | 25.561 / 25.562(c)(5) | Emergency landing conditions; head injury criterion (HIC) | | 25.571 | Damage-tolerance and fatigue evaluation of structure | | 25.581 | Lightning protection | | 25.601 | Design and construction - General | | 25.603 | Materials | | 25.605 | Fabrication methods | | 25.609 | Protection of structure | | 25.611 | Accessibility provisions | | 25.613 | Material strength properties and material design values | | 25.619 | Special factors | | 25.625 | Fitting factors | | 25.629(d)(8) | Aeroelastic stability | | 25.631 | Bird strike damage | | 25.771 | Pilot compartment | | 25.773 | Pilot compartment view | | 25.777 | Cockpit controls | | 25.1301 | Function and installation | | 25.1309 | Equipment, systems, and installations | | 25.1316 | Electrical and electronic system lightning protection | | 23.1308 and 25.1317 | High-intensity radiated fields (HIRF) protection | | 25.1321 | Arrangement and visibility | | 25.1322 | Flight crew alerting | | 25.1323 | Airspeed indicating systems | | 25.1329 | Flight guidance system | | 25.1353 | Electrical equipment and installations | | 25.1357 | Circuit protective devices | | 25.1381 | Instrument lights | | 25.1419 | Ice protection | | 25.1431(a)(c) | Electronic equipment | | 25.1459(e) | Flight data recorders | | Certification specification | Description | | --------------------------- | ----------------------------------------------- | | 25.1501 | Operating limitations and information - General | | 25.1523 | Minimum flight crew | | 25.1525 | Kinds of operation | | 25.1529 | Instructions for Continued Airworthiness | | 25.1581 | Aeroplane flight manual - General | | 25.1583 | Operating limitations | | 25.1585 | Operating procedures | \[Issue: CS-AWO/2] SECTION 4 -SYNTHETIC VISION GUIDANCE SYSTEMS (SVGSS) GENERAL AMC — CS-AWO · CS-AWO Easy Access Rules · EAR revision 14 Aug 2026 [All rules in SUBPART A -ENABLING EQUIPMENT SECTION 1 -AUTOMATIC LANDING SYSTEMS (ALSS)](https://avioverse.aero/regulations/easa/cs-awo/subpart-a) Consolidated from the EASA Easy Access Rules (revision 14 Aug 2026, extracted 13 Oct 2026) for convenience.
