Excellent review. One note on possible ATC delays: Published AARs on the OIS page represent best case for the given runway configuration and weather. On day of operation, Tower calls configuration and TRACON calls the rate, with a number of factors that can modify the published max rate for the configuration. Keep up the good work!

Hi Don - thanks for the note! If you're referring to the AARs found in the east/west directories, we're using historical hourly data (from ASPM) that reflects what was actually called. I really like the directories for a quick glance, but unfortunately it doesn't sound like they're being transitioned to the new site (despite feedback I submitted).

Yep, not on the new public site. I was a beta tester for the new site, and gave the same feedback to the team.

Thanks for making these free. I’m really enjoying learning about something I’ve never been exposed to before.

Quite welcome! In no small part, that's why we're writing.
