Maybe the AF/D is not correct. I've come across errors in it before;
reality trumps theory.

There's a lot of places to look if you care. If you're not sure just
use "tower."


One of the more irksome errors is the TPA - if it is not listed in the
AF/D, it's supposed to be "standard". Well, standards have changed, but
practices haven't, so (for example) GBR (Great Barrington) had the TPA
unlisted, I assumed 1000 feet, but the locals use the old standard of
800 feet. Another aircraft right where I was got my attention real
fast, but I couldn't find her.

TPA is non regulatory, a suggestion only. I never bother to look at
TPA. I'm going to 1000 AGL at every airport unless there's some reason
not to.
