Looks good.
The module tutorial I would hold off and re-do it with the new format for the next version.
Also, I noticed you do this:
$data = ACARSData::GetACARSData($cutofftime=120);
// it's just:
$data = ACARSData::GetACARSData(120);
That's in line with the PHP standards, it would be best to stay with that. There's alot of beginners too, wouldn't want them learning the wrong thing at first
Other than that, what I've seen looks great.
I think I'll upload the other tutorials over to YouTube as well, instead of hosting them there.
