According to some Sheffield graduates, they highly recommend taking the FAA ADX knowledge test before attending Sheffield. Is this the same as the ATP written exam?
No. The ADX (Aircraft Dispatcher) Knowledge test is similar to the ATP (Airline Transport Pilot) Knowledge test, but is separate with regard to the licensing requirements. An applicant for an Aircraft Dispatcher Certificate must pass (>70%) the ADX test. An Airmen report of a passed ATP test is of no use to a Dispatcher applicant.
