AI Deep Dive explanations & Ace, your AI tutor

AI Deep Dive

Most apps just mark an answer right or wrong. AI Deep Dive explains why the correct answer is correct, why each distractor is wrong, and teaches the underlying aeronautical concept — so you understand the material instead of memorizing a letter. Every explanation cites its FAA sources, which you can open in the reference viewer.

AI Deep Dive: the correct answer, why the others fail, and the FAA sources behind it.

Ace, your AI tutor

Ace answers your aviation questions in plain language, grounded in our FAA materials, and cites the source it used. Ask things like "why does density altitude increase on a hot day?" and get a clear, referenced answer — or a polite "that's not in our materials" rather than a guess.
