ExploreAbout this exam
The ANAC Flight Engineer theoretical exam - Exame Teórico de Mecânico de Voo - is the knowledge test that the Brazilian civil aviation authority, ANAC, requires before a candidate can obtain the flight engineer licence (licença de mecânico de voo). The flight engineer is the crew member who monitors and manages aircraft systems in flight: engines, fuel, hydraulics, electrical generation, pressurization and air conditioning, and the associated abnormal and emergency procedures. The licence is associated with older large transport aeroplanes that carry a dedicated flight engineer station, so the candidate profile is usually an experienced maintenance technician or mechanic moving into a flight crew role. The exam is multiple choice and is organised around the ANAC syllabus, which spans aircraft systems and powerplants, flight operations, performance and weight and balance, maintenance and airworthiness, Brazilian regulations, meteorology, navigation, human factors, communications and avionics, and international air law. Preparation should follow the official syllabus rather than a textbook order: work domain by domain, use the current RBAC texts for the regulatory items, and drill systems logic - why a valve opens, what happens when a pump fails - rather than memorising schematics. Practising with timed mixed sets builds the pace you need. ANAC publishes the current question count, time limit, fee and pass mark on its website; confirm those figures there before booking.
What you'll study
About ANAC Flight Engineer Theoretical Exam (Mecânico de Voo) preparation
What is the exam format?
It is a multiple-choice theoretical exam delivered under ANAC supervision, covering the domains in the official syllabus. Each item has a single correct answer and there is no penalty for guessing beyond the pass mark, so answer every question. ANAC publishes the current number of items and the time allowed; check its site before you schedule.
How hard is it in practice?
Most candidates find the systems and performance items hardest, because they test reasoning rather than recall. Regulatory and air law items are easier if you read the current RBAC text directly. The exam rewards broad, even coverage: a candidate who is strong on engines but weak on weight and balance and meteorology usually struggles.
Can I retake it if I fail?
Yes, ANAC allows re-examination, but the rules on waiting periods, the number of attempts and how long a passed subject remains valid are set out in current regulation and can change. Confirm the present retake policy with ANAC or your approved training organisation before relying on a plan that assumes an immediate second sitting.
How much time should I plan for preparation?
Treat it as a multi-month project if you are studying alongside work. A common approach is to cover one syllabus domain per two to three weeks, with the last month reserved for mixed timed practice and review of weak areas. Candidates with recent maintenance experience on relevant types can compress the systems phase.
In what order should I study the subjects?
Start with aircraft systems and powerplants, since they underpin performance and abnormal procedures. Then take performance and weight and balance, followed by maintenance and airworthiness and the RBAC material. Meteorology, navigation and avionics can run in parallel as lighter daily sessions, and human factors and air law are efficient to finish last.
What are the most common failure modes?
Three recur: memorising diagrams without understanding system logic, so questions phrased differently defeat the candidate; skipping weight and balance calculations because they feel tedious; and studying regulations from outdated summaries instead of the current RBAC text. Poor time management in the exam itself also costs marks on longer calculation items.
Where do I confirm fees, dates and pass marks?
Only with ANAC. The authority publishes the current fee, the pass mark, the number of questions, the duration and the scheduling calendar on its official website and through its examination channels. Any figure quoted by a third party, including a training provider, should be verified against that source before you pay or book.
Does holding a maintenance licence help?
Substantially, especially for systems, powerplants and airworthiness items, because you already know how components behave in service. The gap is usually the flight-operations side: performance, weight and balance, meteorology and crew resource management. Budget extra time there rather than assuming your technical background covers it.
How should I use practice questions?
Use them to diagnose, not to memorise. After each set, write down why every wrong option was wrong; that reasoning is what the exam tests. Keep sets timed once you are past the halfway point of preparation, and revisit missed topics a week later to confirm retention rather than recognising the answer.
