Ecco un sunto dei messaggi acars:
* at 3.5 hours before the main events, a 3831 event. Something concerning waste disposal (38 is water and waste, and 3830 is the waste disposal system)
* at 0210, a 2210 event: AP off (22 is Auto Flight and 2210 is the Autopilot system)
* at 0210, a 2262 event (22 is Auto Flight; I have no code 2260)
* at 0210, a 2791 event, flight control switch to alternate law (27 is flight controls; I have no code 2790 or 2791)
* at 0210, two 2283 events, flags raised on CAP and FO Primary Flight Displays (PFD) (22 is Auto Flight, I have no code 2283)
* at 0210, a 2230 event, autothrust off (2230 is the auto throttle system)
* at 0210, a 3443 event, a TCAS problem (34 is navigation; 3443 is the Doppler system. The Doppler system here is used to measure relative motion of another body, in this case another aircraft, for TCAS).
* at 0210, two more 2283 PFD flags
* at 0210, a 2723 rudder travel limiter fault (27 is flight controls, 2720 is the rudder control system). At higher airspeeds, the rudder travel is limited by the Rudder Travel Limiter; far less movement is allowed than at lower airspeeds.
* at 0210, a 3411 event with EFCS 2, reported by EFCS1 (3411 is the pitot/static system. I understand that on these airplanes, the system is divided into the pitot subsystem and the static subsystem).
* at 0210, a 2793 event involving EFCS 1. (27 is flight controls. I understand from colleagues that, on the A330, 2793 is the Flight Control Primary Computer, FCPC, also designated PRIM)
* at 0211, a couple more 2283 PFD flags
* at 0212, a 3410 event. A disagreement between the air data units, the AD part of the ADIRU (34 is navigation; 3410 is flight environment data). An “ADR disagree” can only occur when one of the three ADIRUs has already been designated as faulty by the FCPC, and the two remaining ADIRUs yield discrepant readings (this information from the Aircraft Operating Manual of the A330)
* at 0212, a 3422 event in the standby flight instruments (ISIS) (34 is navigation, 3422 is directional gyro and indicators)
* at 0212, a 3412 event involving IR2, the inertial reference part of ADIRU2 (34 is navigation; 3412 is the outside air temperature sensor and indicator). Reported by IR1 and IR3 and EFCS1.
* at 0213, two 2790 (EFCS) events, FCPC 1 and Secondary FCC (FCSC) 1 faults (27 is flight control; I don’t have the 2790 designator)
* at 0213, a 2283 event, reported by FMGKC1 (22 is autoflight, I understand from colleagues that 2283 is the Flight Management and Guidance Computer, FMGC)
* at 0214 a 2131 event (21 is the air conditioning, 2131 is the cabin pressure controller).
* at 3.5 hours before the main events, a 3831 event. Something concerning waste disposal (38 is water and waste, and 3830 is the waste disposal system)
