FAA Aircraft Dispatcher Knowledge Test (ADX) Practice Test

The FAA Aircraft Dispatcher Knowledge Test (ADX) consists of 80 multiple-choice questions, and you must achieve a score of at least 70% (56 correct answers) to pass. The test is administered via computer at FAA-approved testing centers. This practice test includes 171 questions to provide comprehensive coverage and repeated exposure to key concepts, increasing your likelihood of success.

No, a pilot license is not required to take the ADX exam. However, the FAA recommends that candidates have a strong understanding of aviation fundamentals, including meteorology, navigation, and aircraft systems. Many successful candidates come from backgrounds in aviation management, military operations, or intensive self-study programs. This practice test is designed to bridge knowledge gaps for candidates from diverse backgrounds.

The FAA Aircraft Dispatcher certificate does not expire, but you must complete recurrent training every 12 calendar months to maintain currency with a specific air carrier (per FAR 121.465). This training typically includes flight planning, weather, and emergency procedures. Additionally, you must pass a practical test (oral and practical) every 24 months to remain qualified. The certificate itself remains valid as long as you meet these recurrent requirements.

While this practice test is a powerful tool for self-assessment and reinforcement, it should be used in conjunction with official FAA publications, such as the 'Aircraft Dispatcher Handbook' (FAA-H-8083-10), the 'Aeronautical Information Manual' (AIM), and FAR/AIM guides. The practice test helps you identify weak areas and build test-taking stamina, but comprehensive study of the source material is essential for deep understanding and long-term retention.

Based on industry feedback, the most challenging areas include: (1) interpreting and applying METARs, TAFs, and SIGMETs for alternate airport selection; (2) calculating takeoff and landing performance using charts with temperature, pressure altitude, and wind corrections; (3) understanding ATC separation standards and airspace classifications; and (4) applying FAR Part 121 operational control and dispatch release requirements. This practice test emphasizes these high-difficulty topics to ensure you are fully prepared.
