Due to limited availability of class slots, I had to do my A330 ground school with a class start time of 2 AM. (This time is more suited for leaving a bar than being alert & receptive to technical instruction.)
However, reading some of the knowledgeable detailed technical discussions here, I’m having flashbacks, not to the information presented, but to the difficulty in trying to understand what it actually meant at oh-dark-thirty in the wee hours.
Now occasionally in my head, in imaginary digitized voice, I'm sure I will hear all these computers "broadcasting, receiving, requesting, acknowledging, discussing, granting and permitting".
(Previously I never gave it a second thought with the SS firmly, i.e. lightly, in hand.)
