interim report
Maybe the interim report will inform in details what exactly all those ACARS messages mean with the corresponding docs, including the lav (which lav ?) message.
I still would like to know what could generate that ISIS fault (comparison with ground speed data from the ADIRUs, and so on) and at what moment (realignment, initialization ?)
I also would like to know if discrepancy between pitots is detected directly or through the ADRUs
