Hello,
I just purchased the A350. I love this aircraft, but I thought the product was stable. First flight without any problems. Second flight: orange screens lit up (WASM)... and on the third and fourth flights: it was impossible to initiate a descent (T/D). If I engage vertical descent on autopilot... nothing happens, it maintains altitude. I fly the A320 (Fenix) regularly and don't encounter this problem. Can you help me with this T/D and autopilot issue? Maybe I'm missing something, but I don't understand why the autopilot doesn't respond when I switch to V/S manually.
