Hangar Hobbs

Ten minutes a day. The FAA knowledge, for keeps. A study game for student pilots, built from the documents the examiner uses.

Try a questionHow it preps you

Four-minute lessons

Ten exercises, mixed on purpose: recall, fill the blank, tap a real sectional, work out a number. Wrong answers come back before the lesson ends.

Built from the source

Every question is drafted from one passage of the AIM, 14 CFR, the PHAK or the ACS, with the passage attached. Not a recycled question bank.

Made to stick

Spaced repetition brings each item back right before you'd forget it. Your revs climb when you show you know it, staying Current is three days out of seven, and weekly leagues keep it lively.

The screens

Meet Ace, your co-pilot. He briefs you on the route, salutes a correct answer, and drops his goggles when you miss one.

Try one

A real question from the Airspace unit. Pick an answer, then Check.

Regardless of weather, what must you get before flying into Class B?
Check

What you're seeing:

  1. The question was written from AIM 3-2-3 and nothing else.
  2. The quote under the explanation is copied word for word from that paragraph.
  3. Every distractor has to be definitively wrong according to the passage, not just less good.

How it preps you for the Private Pilot test

The knowledge test and the oral both run off the Airman Certification Standards. Hangar Hobbs is organized the same way.

Mapped to the ACS

Every question carries an ACS code. Progress in the app is progress against the same checklist the examiner uses. The Pro mock test is 60 questions weighted like the real one.

Learn the rule, not the wording

The FAA keeps rewriting questions to break memorized banks. Learn it from the AIM and the regulations and a reworded question is still easy, and so is the oral when it drifts off script.

Beats decay

Ground school teaches airspace in week two. By week six, B, C and D blur together. Spaced repetition schedules each item to return right before it slips, ten minutes at a time.

The whole test, not just recall

The written asks you to read a sectional excerpt and pull numbers from the 91.155 table. So does Hangar Hobbs, on a real chart, checked against the regulation.
