A320 status showing in op systems without prior ECAM caution
Occasionally on MSN >6000 we get an ECAM status page showing
CAT3 SINGLE ONLY with CAT3 DUAL listed under inoperative systems, this without any kind of ECAM warning or caution. Only in the air. Anyone shed some light as to why this might be happening and how, technical speaking, Airbus pilots must treat this when determining landing requirements for an LVO approach?
