Human Factors
Core concepts
Human factors questions test the SHELL model, error management, and the physiology of flight. Know the senses involved in spatial disorientation (somatogravic and somatogyral illusions), hypoxia types and symptoms, and the effects of noise, vibration, and fatigue. Understand the difference between slips, lapses, mistakes, and violations in error classification. Know the role of stress, workload, and situational awareness. Recognize the signs of fatigue and the countermeasures. Understand the concepts of threat and error management and how they apply to the flight engineer's role.
Traps in questions
A frequent trap is assuming a skill-based error is the same as a decision error. Another is confusing hypoxic hypoxia with hypemic hypoxia. Questions about disorientation often hinge on the 'leans' - the somatogravic illusion occurs during acceleration, not steady flight.
Worked example / rule of thumb
When a question describes a crew member misreading a gauge, classify it: if the action was correct but the perception was wrong, it is a mistake; if the action was skipped, it is a lapse. Rule of thumb: recognize, then recover - awareness is the first defense.
Crew Resource Management and Safety
Core concepts
CRM questions test communication, leadership, and decision-making in the cockpit. Know the concepts of assertiveness, briefing, and closed-loop communication. Understand the role of the flight engineer as a bridge between the pilots and the systems, and the importance of challenging a decision when safety is at risk. Know the meaning of situational awareness, shared mental models, and workload distribution. Understand the safety management system (SMS) and the difference between reactive, proactive, and predictive safety management. Know how to report hazards and how just culture supports reporting.
Traps in questions
A frequent trap is assuming CRM is only about personality - it is about behavior and process. Another is confusing a briefing with a checklist; a briefing sets the plan, a checklist verifies it. Questions may test who speaks first when an error is detected; the answer is anyone who detects it, using a clear challenge.
Worked example / rule of thumb
Use a structured challenge: state the concern, state the consequence, propose an action. Rule of thumb: if you see something, say something - early and specifically.
Communications
Core concepts
Communications questions test radiotelephony phraseology and the use of standard call signs and readback. Know the standard phraseology for taxi, takeoff, climb, descent, approach, and emergency. Understand the difference between VHF and HF, and the role of SELCAL. Know the phonetic alphabet, standard readback requirements, and the meaning of 'say again' and 'standby.' Understand the emergency frequencies (121.5 MHz) and the use of transponder codes. Also know how to pass a position report and how to relay a message.
Traps in questions
A common trap is assuming a readback is optional - for safety-critical clearances it is mandatory. Another is confusing 'wilco' (will comply) with 'roger' (received). Questions may test the correct phraseology for a go-around or an emergency descent.
Worked example / rule of thumb
When receiving a clearance, read back the items that change the flight path or altitude. Rule of thumb: if it changes where you go or how high you fly, read it back.
Instruments and Avionics
Core concepts
Instruments and avionics questions test the principles of pitot-static and gyroscopic instruments and the interpretation of electronic displays. Know how the airspeed indicator, altimeter, and vertical speed indicator work, and the errors that affect them (position, compressibility, lag). Understand gyroscopic rigidity and precession, and how they support the attitude indicator and heading indicator. Know the principles of the turn coordinator and the magnetic compass. Understand the meaning of glass cockpit displays, the flight management system, and the automatic flight control system. Know the significance of the master caution and warning system.
Traps in questions
A frequent trap is confusing a blocked pitot tube with a blocked static port. A blocked pitot makes the airspeed read like an altimeter; a blocked static makes airspeed and altitude unreliable together. Another is assuming the magnetic compass turns smoothly - it leads and lags during turns.
Worked example / rule of thumb
If the static port blocks, the airspeed indicator behaves like an altimeter and the VSI freezes. Rule of thumb: pitot affects airspeed; static affects all three pressure instruments.
Air Law and International Standards (ICAO Annexes)
Core concepts
Air law questions test the framework of international civil aviation under the Chicago Convention and the ICAO Annexes. Know the roles of ICAO, the Council, and the Assembly, and how Annexes become binding through national regulation. Understand the key Annexes: Annex 1 (Personnel Licensing), Annex 2 (Rules of the Air), Annex 6 (Operation of Aircraft), Annex 8 (Airworthiness), Annex 11 (Air Traffic Services), Annex 14 (Aerodromes), and Annex 19 (Safety Management). Know the meaning of standards and recommended practices, and the difference between them. Understand the freedoms of the air and the concept of nationality of aircraft.
Traps in questions
A frequent trap is confusing a standard (binding unless a difference is filed) with a recommended practice (desirable, not mandatory). Another is assuming an ICAO Annex applies directly - it applies through the state's regulation. Questions may test which Annex covers which subject.
Worked example / rule of thumb
When a question names an Annex, match it to its subject before answering. Rule of thumb: Standards are 'shall,' Recommended Practices are 'should' - and states must notify differences.
