Study for the FAA aircraft dispatcher knowledge test (ADX) and the flight dispatcher exams of Canada and the UAE: over 2,000 original questions, chart lessons, dispatch trainers and timed mock exams. Choose a region; each keeps its own papers, progress and mock exams.
United States: the aircraft dispatcher knowledge test
ADX — 80 questions, 3½ hours, 70% to pass. 706 original questions in 53 topics: Parts 65, 91, 121 and 135 and NTSB 830, meteorology and US weather products, navigation and charts, ATC and airspace, flight planning and performance, weight and balance, aircraft systems, aerodynamics, human factors and emergencies.
Three lessons on US products: a METAR and TAF, the prog charts and winds aloft, and a US NOTAM. A Go / Alternate / Delay trainer works from a Part 121 release folder: alternates, fuel and the TAF at the ETA.
Canada: two papers, tracked separately
FDOPS — 80 questions, 3½ hours, 70% to pass. Air law and ATS procedures, airframes, engines and systems, instruments, navigation and flight planning, radio aids, flight operations, theory of flight and human factors.
FDMET — 100 questions, 3½ hours, 70% to pass. The atmosphere, moisture and stability, air masses and fronts, lows and cyclogenesis, tropical weather, icing, thunderstorms, and the Canadian weather products a dispatcher works from.
Over 990 original questions in 88 topics across all nine subject areas of the Study and Reference Guide for Flight Dispatchers, each checked against the current CARs and TC AIM, with an explanation and a reference.
The dispatch desk: a new release every time
A computer flight plan with the full fuel block, a load and trim sheet with percent MAC, and a METAR, TAF and upper wind folder for a destination and its alternate, worked together from one tap on Home.
Learn to read the charts
Four lessons with numbered callouts: the GFA, the high-level significant weather chart, the upper-air analysis and a NOTAM, plus a GFA chart reader drawn fresh each time.
Go, alternate or delay?
Release as filed, change the alternate, delay or do not release, each decided by the rule it rests on.
UAE: GCAA flight dispatcher
312 original questions in 24 topics on the ICAO-based subjects of CAR II Chapter 6, Appendix I: air law and ATS, aircraft general knowledge, performance, planning and loading, human performance and TEM, meteorology, navigation, principles of flight, radiotelephony and operational procedures. A 60-question practice paper is scored at the 75% pass mark; its length and timing are our own, as the official structure is not published.
