Mathematics for Aircraft Maintenance

This module contains instruction in basic mathematics for the aviation maintenance technician as prescribed by EASA Part 66/147 for the B1, B2 rating. For most students, this module is a review of the principles learned previously in life. Those being exposed to these mathematic principles for the first time may require remedial training.

There are many applications for mathematics in aviation maintenance. the goal of Module 1 is to review the basic mathematic knowledge that a certified maintenance professional will need.

This manual is presented in 3 chapters:

1] Arithmetic

Arithmetical terms and signs, methods of multiplication and division, fractions and decimals, factors and multiples, weights, measures, and conversion factors, ratio and proportion, averages and percentages, areas and volumes, squares, cubes, and square and cube roots

2] Algebra

a) Evaluating simple algebraic expressions, addition, subtraction, multiplication and division, use of brackets, simple algebraic fractions.

b) Linear equations and their solutions, indices and powers, negative and fractional indices, binary and other applicable numbering systems, simultaneous equations and second degree equations with one unknown, logarithms.

3] Geometry
