CAAB AME B2 Exam study guide

CAAB AME B2 Exam · Work through your exam, one topic at a time.

The CAAB Aircraft Maintenance Engineer Licence - B2 (Avionics) is the Bangladesh Civil Aviation Authority's basic-knowledge qualification for engineers who intend to certify avionics and electrical/electronic systems work on civil aircraft. It is aimed at trainee and practising avionics maintenance personnel who need to demonstrate a broad, theory-level understanding before moving on to type-specific training and certifying privileges. The CAAB AME B2 Exam study guide has 10 sections and about 3,287 words.

01

Mathematics

Aviation mathematics is applied arithmetic, not abstract theory. You must handle fractions, decimals, ratios, proportion, percentages, powers and roots, simple algebra, geometry, and right-angle trigonometry.

296 words, about 1 min
02

Physics

Physics for avionics maintenance covers SI units, scalars and vectors, kinematics, Newton's laws, work, energy and power, momentum, pressure and density, fluid flow, temperature and heat, gas laws, basic optics, and wave motion. You should distinguish mass from weight, gauge pressure from absolute pressure, and static pressure from dynamic pressure.

349 words, about 2 min
03

Electrical Fundamentals

You must be confident with Ohm's law, series and parallel circuits, Kirchhoff's voltage and current laws, electrical power, and the behaviour of resistors, capacitors and inductors. In DC circuits, know how voltage divides in series and current divides in parallel.

339 words, about 2 min
04

Electronic Fundamentals

Electronic fundamentals covers semiconductor materials, PN junctions, diodes, rectifiers, Zener diodes, LEDs, bipolar transistors, field-effect transistors, operational amplifiers, filters, oscillators, power supplies and decibel notation. You should know that a diode conducts when forward biased above its threshold and blocks in reverse until breakdown.

322 words, about 2 min
05

Digital Techniques and Electronic Instrument Systems

Digital techniques includes number systems, binary arithmetic, two's complement, BCD, hexadecimal, logic gates, Boolean expressions, combinational and sequential logic, flip-flops, counters, registers, memory, buses, and analogue-to-digital conversion. You should understand the difference between serial and parallel data transfer, and between one-way and bidirectional buses.

332 words, about 2 min
06

Materials and Hardware

Materials and hardware covers ferrous and non-ferrous metals, alloys, heat treatment, corrosion, composites, fasteners, threads, rivets, bearings, cables, pipes, seals and springs. You must know the difference between strength, hardness, ductility and toughness, and why aluminium alloys are used with protective treatments.

322 words, about 2 min
07

Maintenance Practices

Maintenance practices covers safety, workshop practice, tools, calibration, torque, lockwiring, inspection, non-destructive testing, fault diagnosis and documentation. You must understand how to select and care for tools, why calibration is controlled, and how to apply torque correctly.

329 words, about 2 min
08

Basic Aerodynamics

Basic aerodynamics covers the atmosphere, standard atmosphere, airflow, lift, drag, thrust and weight, stability and control. You should understand the lift equation, the four forces in steady flight, and the difference between parasite drag and induced drag.

325 words, about 2 min
09

Human Factors

Human factors examines how people interact with aircraft, tools, procedures and each other. The SHELL model describes software, hardware, environment and liveware, with the central liveware representing the person.

318 words, about 2 min
10

Aviation Legislation

Aviation legislation covers ICAO standards, the EASA basic regulation, Part-21 design and production, Part-66 maintenance personnel licensing, Part-145 maintenance organisations and Part-M continuing airworthiness. You must know the privileges and limitations of a B2 licence, which covers avionics and electrical systems, and how it differs from B1 mechanical certification.
