"The ACARS also contains protocols to support retry of failed messages or retransmission of messages when changing service providers."
Interfug asked if it's a complete list, So: How often does it retry? We know it got off what? 27 total faults and warns (including 3 mtc status wrns) for four minutes straight, so the acars system had normal DC and was functioning. I don't see how there could be any missing messages between 0210 and 0214z since ACARS breaks the info up into blocks (where's AVspook?, he probably knows the answer to this) This is the world of data bits and verification and secondary resends: only a real "TRON" can verify that when it's got a lock it's streaming fast. Wiki only says:
Its can be programmed for number of retries - This is the VHF ACARS they are talking about, on some AB's will ahve a dedicated provider eg SITA however you may alos have the option to swicth to another provider (Arinc) however it will keep interrogating the SAT until it offload its message.
The company i worked for the VHF had 3 goes at offloading the ACARS before switching to SAT , It figured if it missed 3 offloads it must be out of range of a Line of site VHF station & then switched to the more expensive SAT option.
No HF mesgs - no hf fault same for engines same for Inertial Data from the ADIRU teh ACARS Hit the SAT... It knew where the aircraft was (lat long) it knew where to find the SAT and it beam steered the Antennae to get that hit
at the Maintenance center for both Boeing (Aircraft Health Management option) and airbus (AirMan Option) the messages will pop up allowing access to order parts send repair info to the arrival station while the aircraft is in flight. The LAT/LON of the aircraft also used to show on the screen and on the AirMan option you could view a realtime globe of your fleet
