The FAA ADX exam is an 80-question, 210-minute Airman Knowledge Test with a 70% passing score. As of March 2026, PSI lists the standard Airman Knowledge Test fee at $175. Passing ADX is only one step: applicants also need the practical test and either qualifying experience or graduation from an approved 200-hour dispatcher course under 14 CFR 65.57 and 65.61.
About the FAA ADX Exam
The FAA ADX Aircraft Dispatcher knowledge test is the written exam used on the path to an aircraft dispatcher certificate under 14 CFR Part 65. It tests the judgment and technical knowledge required for airline dispatch work, including operational control, meteorology, navigation, aircraft performance, dispatch releases, ATC coordination, abnormal operations, and practical flight-planning decisions in Part 121-style scenarios.

Frequently Asked Questions
How many questions are on the FAA ADX knowledge test?
The FAA testing matrix lists the ADX knowledge test at 80 questions with 3.5 hours allowed. The passing standard is 70 percent. The exam is delivered as a computer-based FAA Airman Knowledge Test through PSI.
Can you take the ADX knowledge test before age 23?
Yes. Under 14 CFR 65.53, you must be at least 21 years old to take the aircraft dispatcher knowledge test, but you must be at least 23 to be eligible for the aircraft dispatcher certificate itself. That distinction matters for candidates who want to complete ADX early while finishing experience or training requirements.
What experience or training do you need for the aircraft dispatcher certificate?
14 CFR 65.57 allows two main paths. You can present qualifying experience from the prior 3 years in approved aviation roles, or you can present a statement of graduation from an approved aircraft dispatcher course. The course itself must cover Appendix A topics and include at least 200 hours under 14 CFR 65.61.
Does the FAA publish official ADX percentage domain weights?
Not publicly in the same way many professional exams publish scored percentages. The FAA publishes the required knowledge areas in 14 CFR 65.55 and the broader dispatcher-course domains in Appendix A to Part 65, but it does not publish a public scored ADX percentage blueprint. For study planning, candidates should assume the heaviest emphasis falls on weather interpretation and practical dispatch decision making.
What is the current FAA ADX test fee?
PSI's FAA Airman Knowledge Testing site lists the standard Airman Knowledge Test fee as $175, with a note that price may vary by testing location. You schedule and pay through the FAA/PSI testing portal rather than directly through the FAA.
What changed recently for the ADX exam?
As of the FAA Airman Testing Community Advisory dated February 27, 2026, I did not find a new ADX-specific blueprint change announcement. The latest explicit ADX change I found in FAA testing advisories is the November 2024 special edition, which said 10 ADX questions were revised or replaced while the blueprint remained unchanged. That same advisory also referenced the incorporated-by-reference rule changes that became effective on May 31, 2024.
