And the answer to the question, "How many?"

About 1.5 million per year.


Thanks! It looks like individual messages are rarely more than one, under-80-character line long.

So we're talking, (1.5M * 80 bytes=) 120MB a year, uncompressed. (With the tiny controlled-vocabulary, maybe 6x compression possible?)

Every pilot could have a RAM-resident local queryable copy in a their commodity handheld devices.


This is great stuff, thanks! Can't shake the feeling a tiny team of professional modern software/system designers, paired with some aerospace old hands, could create a far-better (but also backward-compatible) system in short order.
