EASA Part 66 – Engineering CAT B2 – Question Bank

£99.99 / month

Module 1: Mathematics

Module 1 covers the basic arithmetic, algebra and geometry that lays the foundation for the equations used in the modules that follow (physics, electrical fundamentals and electronic fundamentals).

Module 2: Physics

The physics module provides knowlegde of matter (structure of atoms, molecules etc), mechanics (forces, movement, energy etc), thermodynamics, optics (light) and sound.

Module 3: Electrical Fundamentals

This module provides the fundamental electrical knowledge required for an aircraft maintenance engineer and the basis for the electronic fundamentals module that follows. The content includes electron theory, generation of electricity, capacitance, magnetism, inductance, transformers, generators and motors.

Module 4: Electronic Fundamentals

This module follows on from the electrical fundamentals module and covers components (diodes, transistors and integrated circuits), PCBs (printed circuit boards) as well as including information on different types of servomechanisms (also known as synchros). There are different versions of this module (B1 or B2) as the knowledge requirement is more in-depth for those studying towards a B2 licence.

Module 5: Digital Techniques / Electronic Instrument Systems

Module 5 includes data, databuses, logic circuits, microprocessors, fibre optics and typical digital aircraft systems.

Module 6: Materials & Hardware

This module begins by covering the wide range of aircraft materials in use today (such as alloys and composites) enabling students to apply their knowledge of atomic structure from the earlier physics module to understand of the characteristics and properties of these materials. The module then introduces components such as fasteners, pipes, springs, bearings, gears, cables and connectors which feature in the maintenance practices module.

Module 7: Maintenance Practices

This module focuses on typical aircraft maintenance activities that are performed such as the assembly, inspection and testing of components as well as the associated tools, safety precautions and engineering standards.

Module 8: Basic Aerodynamics

The basic aerodynamics module builds upon knowledge from the physics module and includes the atmosphere, aerodynamics and the theory of flight.

Module 9: Human Factors

Within a maintenance environment it is essential that human factors are taken into account. By understanding human performance limitations, social psychology, communication and the factors affecting performance we can minimise the likelihood of incidents attributable to human human error.

Module 10: Aviation Legislation

This module covers the aviation regulatory framework (such as the role of the ICAO and EASA), certifying staff, aircraft certification and international requirements.

Module 13: Aircraft Aerodynamics, Structures and Systems (Avionic) – COMING SOON

This extensive module builds upon the knowledge from earlier modules and provides explanations of aerodynamics and all the main systems found in modern civil aircraft to a level applicable for those studying towards B2 licences: general concepts of aircraft structures, autoflight, communication, navigation, electrical power, equipment & furnishings, flight controls, instruments, lights, onboard maintenance systems, air conditioning, cabin pressurisation, fire protection, fuel systems, hydraulic power, ice & rain protection, landing gear, oxygen, pneumatics, water & waste, integrated modular avionics (IMA), cabin systems and information systems.

Module 14: Propulsion

This module provides the knowledge of aircraft engines at a level applicable for those studying towards B2 licences (as they do not study the much more in-depth Module 15: Gas Turbines). It includes a general overview of turbine engines followed by explanations of engine indicating systems and starting & ignition systems.
