Frequently Asked Questions
What is the FAA CBG Knowledge Test?
The FAA CBG exam is the official FAA aeronautical knowledge test required for obtaining a Commercial Pilot Certificate with a Lighter-than-Air category and Gas Balloon class rating under 14 CFR Part 61.
How many questions are on the official FAA CBG exam and what is the time limit?
The official computer-based exam contains 60 multiple-choice questions with a time limit of 2.5 hours (150 minutes). The passing score is 70% (42 out of 60 questions correct).
What flight experience is required under 14 CFR 61.129(h) for a Commercial Pilot Gas Balloon rating?
Applicants must log at least 35 hours of flight time as a pilot, including 20 hours in gas balloons, 10 flights in gas balloons (including 6 with an instructor), 2 flights of at least 2 hours duration, 1 ascent to 5,000 feet above the launch point, and 1 solo gas balloon flight.
What lifting gases are covered on the FAA CBG examination?
The exam covers Helium (He) and Hydrogen (H2), focusing on their molecular weights, net lift capacity per 1,000 cubic feet (approx. 65-66 lbs for helium vs 71-72 lbs for hydrogen under standard atmospheric conditions), safety handling, and thermal expansion properties.
Does the FAA publish topic weightings for the CBG knowledge test?
No. The FAA Airman Knowledge Testing Matrix publishes the test code, question count, minimum age, allotted time and passing score, but no percentage breakdown by subject. The content outline and percentages shown on this page describe how this free practice bank distributes its questions across the knowledge areas drawn from the applicable FAA testing supplement, Airman Certification Standards or Practical Test Standards, and the FAA handbooks for this test.
