About the Commercial test

The Commercial Pilot (Airplane) knowledge test covers advanced regulations, aircraft performance and systems, commercial operations, and aeronautical decision-making at a higher standard than the private test.

You take it if you are pursuing a Commercial Pilot Certificate, which allows you to be paid to fly and is the step toward professional flying jobs.

The Commercial Pilot, Airplane knowledge test has 100 questions and requires 70% to pass, which is 70 correct. It is a computer-based test given at a PSI test center for a $175 fee. You must pass with 70% or higher before taking the practical test (checkride) or oral and practical for your certificate.

Aviator IQ's bank for this test holds 1,461 practice questions across 37 categories, each grounded in Airplane Flying Handbook. Every question shows an explanation and cites the section it comes from, so a wrong answer teaches the rule rather than just marking you down.

A passing knowledge-test result is one requirement. A certificated instructor still endorses you, and the practical test or checkride is separate. Aviator IQ prepares the knowledge test so that step is behind you.

Common questions about the Commercial Pilot, Airplane Test

The Commercial Pilot, Airplane knowledge test has 100 questions and is delivered on a computer at a PSI testing center. The passing score is 70%, which means you need 70 correct. Our bank holds 1,461 practice questions across 37 subject categories, so you can drill well past the length of a single sitting.

A sitting at a PSI testing center runs about $175, and if you do not pass you pay that fee again for each retake. Aviator IQ Pro is $29 paid once, so the goal is to walk in ready and clear the 70% mark on the first attempt.

Every question is written from Airplane Flying Handbook and the other FAA source documents for this certificate. Each one carries a verbatim quote from the source, and that quote is checked against the document before the question ships, so a wrong answer teaches the rule rather than just marking you down. When the FAA reissues a handbook, the questions that cite it are pulled for review.

No. Aviator IQ is test preparation only and is not affiliated with the FAA. Under 14 CFR § 61.35 the authorization to take the official knowledge test comes from a certificated instructor or an approved course, not from a prep tool. The knowledge test is also only one requirement: the practical test or checkride is separate.

No. Pro is $29 paid one time and never renews. It unlocks every subject category, all practice runs, the full-length exam simulator, hints, and the readiness score. There is no monthly or annual charge.
