The #FAA requires a 70% to pass #pilot licensing tests.
This appears to be, in large part, because the tests are absolute garbage. They are ambiguously-worded, they have questions about ratings you're not even trying to get, and the charts they provide have larger margins of error than the gap between answers.
If this test weren't so incompetently assembled, they could require 90% to pass and have more qualified pilots as a result.
I will literally never remember the difference between categories of aircraft with respect to the certification of aircraft and categories of aircraft with respect to the certification of airmen, which are somehow two totally different things.
