HELP-button
Please bear with me!
I have already at least once before argued that the so called "memory item" to apply on triple airspeed disagrement perhaps should be preprogrammed with automatic execution on pressing some kind of Help-button.
However, I am still a little surprised about the lack of details on the automatic systems in the two BEA reports. Is pitot failure a priori assumed to be the main cause?
Another question that comes into my mind is the frequency of data transfers either by polling, by local timing in the various devices, or random (i.e. as soon as data are available and the bus is free to use for transmisson).
Is there a detailed system and program description (or specification) available somewhere?
