From the Airbus response document: 4.3 During the aircraft manufacturing process, the ECF is embedded into a surfacing film which is then co-cured on to the CFRP. This means that the ECF layer forms an integral part of the airframe 21.4.1 (3) The memorandum found that the initial “crazing cracks” p...

Jump to postAs I said, the mesh has a layer of composite resin above it. This is beyond dispute.

Very little in aircr...

The mesh under normal conditions is covered by a composite layer and paint. The A350 uses HexPly M59XF expanded copper foil prepreg, that is on the outside of the structural components, there is no covering composite layer. The structural component is inside that, which is the reason when the mesh ...

In the US, Q Routes only require RNAV 1, which can be met by DME/DME/INS systems or GPS, but T routes additionally require GPS (to an RNAV 1 or better standard)or GPS/WAAS (which meets at least an RNAV 0.3 standard BTW).
